@@eltonwild5648 Hey! You might have figured this out already but getting into sound design can depend on what you want to create sounds for. I'd say the three broad types are for video (movie/tv/animation/ect.), video games (same techniques as video but implementing them into video games takes special knowledge), and for software tools (where coding languages such as the above video come in handy). I am not as familiar with sound design for software tools (one of the many reasons I'm on this video) but for video and video games, the main tools you'll want are this: 1. A DAW (Digital Audio Workstation) such as Pro Tools, Ableton, Adobe Audition, Logic, Reaper, ect. - This is your main workstation, your canvas if you were painting. Every sound that you have recorded will be put into here to edit/manipulate and your virtual audio tools (VSTs usually) will be integrated with this. 2. Field Recorder/Audio Recording Equipment - Most sound designers manipulate audio that they record themselves. Don't feel the need to buy fancy expensive audio recording equipment if you're just starting, smartphone audio recording is a great way to get started. - Field Recording Equipment is used when you're outside of a controlled studio environment (EX: Recording ocean waves, Vehicles, ect.) - Studio Recording Equipment is probably a better choice to start with since you can record anything you bring into your studio and it will be as controlled as the environment you choose to record in (Bedroom, Basement, Home Built Studio, ect.). For this you'll want a microphone and an audio interface (microphone plugs into audio interface, audio interface plugs into computer. You can then record directly into your DAW) 3. Free audio websites (Freesound is my favorite website and probably the most popular for practical sound effects such as crowds, explosions, car engines, ect.) - These are great resources for when you don't have any recording equipment but you want to get started in sound design ASAP. it's also a great resource when there is a sound that you have no way of replicating/recording. Once it gets beyond just a hobby and becomes professional, then this resource gets a little dicey since you're using someone else's work. But getting paid to do sound design might be harder than learning sound design lol believe me. 4. Audio Middleware is used for implementing your sound design into video games I would recommend working on your sound design skills for video before attempting this. A good way to practice with video is taking a movie/tv/animation scene and removing all of the sound. Then you can put your video into a DAW (some DAWs aren't nice with video, might take some configuration) and record and manipulate sounds to redesign the sound for that scene. If you want to attempt video games, then you would want these tools: - Audio Middleware (Wwise and FMOD are the two most popular software though there are probably others) - Wwise works very well with Unity game engine from my experience, while I've noticed FMOD is often used with Unreal Game Engine. I don't have much experience outside of Wwise/Unity though, so other combos probably work well too. - Basic C# can be helpful when working with Game Engines though it's not required if you're working solely in an audio middleware. But if you're doing this project completely by yourself, then you'll need C# knowledge for the video game engine scripting . This is why I don't recommend starting with this. I hope this helps, there are a lot of great resources/communities on reddit, facebook, and other forums. I would also search on TH-cam for how your favorite movies, tv shows, video games did their sound design. There's often behind the scenes videos or interviews with the sound designers where they show their process. And if you need to create a specific sound, many TH-camrs have created videos showing their process of how they created those sounds. Some googling can do wonders once you know what to even Google. Lastly, remember to HAVE FUN or else this isn't worth pursuing. It's a lot of hard-work and takes technical skills, but you need to keep your creativity because this is still a creative hobby/profession. You are the one imagining what worlds sound like for an audience and it can be an amazing feeling when they feel like they've been sucked into the world you helped create. EDIT: I totally forgot about sound design for live productions such as theater. The same principles apply as with video, but you'll need equipment to trigger the sounds while a live production is going on. I would google equipment that can do this as I don't have a ton of experience with a live setting.

43:30 [Part 5] Quick Tip for everyone wondering how to do that on Windows in Visual Studio (I use 2017) : In the Solution Explorer panel, right-click on the Project "[plugin name]_VST3" > Properties. Then go to "Debugging" and set Command to the path of your AudioPluginHost's DEBUG (!) Build executable (change "$(TargetPath)" to, for example, "C:\Juce\AudioPluginHost\Debug\AudioPluginHost.exe"). Set this Command for every configuration (Debug/Release) of PluginName_VST3. Attention: This only affects the [PluginName]_VST3 project, not _StandalonePlugin. When you click Debug, VS will run whatever project is set as the main Startup project for this solution (by default it's _StandalonePlugin = the one printed bold in Solution Explorer), so run _VST3 directly via Right-Click>Debugging>Start (or assign _VST3 as the main Startup project). This way, Visual Studio will launch the AudioPluginHost.exe (which IIRC automatically loads the last saved .filtergraph file) and go into debugging mode - so breakpoints, logs etc should work, too.
To all those getting an error at around 1:12:40--I fixed it by going to the ChainSettings struct in PluginProcessor.h and changing "int lowCutSlope" to "Slope lowCutSlope". I suspect Matkat accidentally cut out the part where he did that haha
Just one thing. I don't recommend to use developer branches to install dependencies (frameworks os libs), because master would be always the best choice, since master branch reflects the latest version, without any insecure or testing features, refactorings or any kind of thing that is not validated to be in production.
@Dsus man, the master branch should be the latest stable. Evertything that is in release or dev branches are implementations in a QA or even dev stages and in a serious projet you never want to be in the risk of breaking something because you are relying your project to something that is not done yet.
Your courses (both free and paid) have been incredibly valuable to me! Imagine how it feels to learn the knowledge and gain the confidence to design and build your own audio plugin. Thanks again!
@@MatkatMusic Hey weird question but what color theme are you using here? Also thanks so much for this tutorial! Currently about halfway through it working along and it's been incredibly informative.
as an computer engineer, I never delved into much graphical C++ but not only does this look awesome, I can say that your choice of GUI really gives insight into what you're doing to the entire frequency range and would even be a cool tool for those learning about network analysis and frequency response curves for circuits! much more informative than those little sliders or pre-selected stock equalizers
^^ this me right now, but also I'm building this as a precursor to learning to build analogue synths. I'm in EE and kinda dream of just building my own whacky things for people to geek out over.
Just started looking into audio programming last week and this pops up. Incredible. *Edit: this is a really well made and high quality tutorial. Thank you!
This is an A+++ video. Thank you! I have run into a few little snags. For example, gotta know to click that button in Juce screen to open the project in xcode (as someone commented below). Also, the audioPluginHost kept crashing when I tried to scan for plugins. Just need to change the scan mode to out of process or something like that (bottom right of the screen). I am about 45 minutes into this video and loving it!!! Have been wanting to find something like this for months.
Sweet Tutorial! Really fun to build out. Instead of creating 2 functions to create both the high and low pass coefficients, you can create one function and pass in a pointer to the butterworth method ie. Have a parameter juce::ReferenceCountedArray(*func)(float, double, int) and the argument would be &juce::dsp::FilterDesign::designIIR[Low/High]passHighOrderButterworthMethod
This is great, though I can see most people still getting lost in the very verbose and exacting syntax of C++. Make sure you get a strong handle on strong typing, and understand C++ style classes, namespaces, pointers, and inhertance well or your brain will explode at some point. Expecially if you come from a scripting language background
Hi rob i am learning dsa in c++ and i can say i have a good hold of c++ if not data structures. I was looking for some projects for my resume and i don't know if these projects put off recruiters. I have no connections with my seniors since we are in a pandemic. What do you recommend? Should i build this or pass?
Just a minor thing. When Projucer starts and you switch to XCode to start looking at the code, you don't show the users who've never used JUCE how to switch. You eventually do when changing the language to C++17, and then hit the icon to save and launch the IDE, but not before that. I know it is minor, but every step counts in these tutorials. There are so many bad ones out there that some users give up at the first sign of something not working or being glossed over. Having said that, I think this is going to be a great tutorial and a God-Send for me. Thank you for this :)
@@MatkatMusic Yep, I am going through the 7 day trial right now and all of the explanations are there. I definitely recommend it for new subscribers, before starting this course. The quality of the content is remarkable.
40:13 [Part 5] Quick Tip for VS2017 (Windows) if AudioPluginHost doesn't find your .vst4 : VS saves the .vst3 file only to its [...]\x64\Debug folder. You have one of 3 options: 1) In AudioPluginHost, add this directory when scanning for new VST3 files / 2) Copy the file by hand to a common VST3 directory (C:\Program Files\Common Files\VST3) / 3) In Solution Explorer Panel, right-click the project [PluginName]_VST3 > Properties > Build Events > Post Build and set "Command" to, for example, [ copy /y "$(TargetPath)" "C:\Program Files\Common Files\VST3\$(TargetFileName)" ] Attention: Post-build copy command will fail if the .vst3 file is locked (e.g. because it's currently being used by AudioPluginHost.exe)
In my Debug folder there is Shared Code folder and Standalone Plugin folder. I can't find any .vst3 file in my project. Is there some initial setup I have to do in VS for it to build this .vst3 file like do I have to install the VST SDK or is it just some setting I have to change?
@@jeremiedsouza6703 Is there a VST3 project in the Solution Explorer inside VS? If NOT, you probably 1) made an Audio Application (make a new Projucer project and select Audio *Plugin*) or 2) unchecked VST3 in the project settings (gear icon inside Projucer > Plugin Formats). If there IS a VST3 project, you probably just need to right-click > Build it from inside Visual Studio's Solution Explorer panel.
You explanation is to MAC justified,..if I'm going to pay for the class it'd be nice if you gave more info for the PC end,...I shouldn't have to decipher this myself,...all respect. This is all very intriguing and I'd like to participate if I could on Windows.
WOW WOW WOW WOW WOW WOW WOW WOW WOW WOW WOW WOW I can't believe this. Is it real What the Hell LOOOOL Always dreamed of programming audio tools but didn't know where to begin. This is the best thing that ever happened so far this year!!! Thank you very much Gilfoyle
Awesome tutorial. The best part is showing the end result in the beginning before coding everything from scratch, fast forwarding code typing and the regression testing by demo. Anything not perfect?, well on a personell matter I prefer to avoid the variable name "i" since it is so closely resembling a "1", I prefer a "n" especially in dsp-code for indexes. and some speaker audio is sometimes doubled and even delayed, not a biggie. and there is a cat distraction, very refreshing :-), Trixie?
See, I always imagined that programmers had to program and engineer exactly how audio is converted, and what it actually is. All that stuff is underneath the implementation of it, and there does not seem to be a whole lot of designing or work at that lower level. My conception of programmers was way way off - kind of - because they did actually have to do that but it appears that those are solved problems by now, thus "standing on the shoulders of giants", but I cant shake the feeling that Im not a "real" programmer unless I get down into machine code.
On OS X Sonoma 14.2 and Juce 7.0.9 (develop branch) if you get a codesign error while building the VST3 target, make sure to Enable the "Use Hardened Runtime" option in the project's Projucer / Xcode (macOS) settings and tick the relevant "Hardened Runtime Options" then export to Xcode and build again.
This is an awesome tutorial. As a professional C++ programmer I am very happy that you are both refactoring code, and using template functions to do so. I am always disappointed by software developers who cannot refactor, especially in tutorials, but I see it in the professional world all the time as well, and many cannot work with template functions at all. Thank you for spreading the word about good practices in coding :)
@@MonsterDAW Refactoring is the process of simplifying code by factoring out repetitions, and abstracting the code to make it more reusable. The techniques for doing this require some time and practice.
@@glitchgatsby4290 I prefer the term good practices, it is hard to judge what is best. The application of a particular practice may be good, or bad, or the best way to do something. This is somewhat subjective and depends upon the situation. There are many books that discuss best practices, and each company has its own set of them. It is hard to say what source would be good, but if you do a search for software best practices you will find many.

Q is called bandwidth and it's units are expressed as decibels per octave or dB/oct, just the same as the slope on the low and high cut filters are. They are fundamentally the same mathematical function except the peak band has a mirrored high/low cut around it's centre frequency.
Man I'm all too excited about this video just from watching the intro!!!!!,.... I thought I was this cool guy who plays the guitar,....am I really a geek?
This is just great. Really, thanks! I hadn't been doing any serious development since the days of Win 95, and in the mean while focused on different flavors of audio engineering. Finally set up in a decent flat with a room to spare for a home studio, and I want to DIY as much as humanly possible due to budget constraints, but, more importantly, for the sake of customization. I'm no slouch with the soldering iron & oscilloscope, but thanks to your excellent introduction to this new skill set I feel like my horizons have widened by orders of magnitude... Keep up the good work!
Ouch this hurts a lot, i recently wanted to make a plugin as a present fo a friend who is interested in music making but i had no clue what to do so it took me a whole month to learn the basics and now this course comes out :(
I'm glad someone recognized it! The mic sounds awesome! It's a shame ScreenFlow has bugs normalizing the audio when you chop up a 5hr video into 10,000 clips and produces clipping audio!!
@1:15:04 aww man I was thinking this the whole time but decided not to do it cause I was under the impression that actually using fallthrough on a switch statement was a C++ cardinal sin lmao. It makes it look cleaner definitely but I'd imagine it might make it a little harder to understand if you don't immediately notice the missing breaks.
@@ilearncode7365 FL is pretty great. It did get that reputation back when it was bundled with sound cards, though. Mostly because of it's colorful UI. Sounds like you haven't researched DAWs in a while.
I forgot to add, FL is developed in Pascal (I believe specifically Embarcadero's Delphi). Pascal is a lovely language and can do what C does. Nowadays it's called "Modern Pascal" or "Object Pascal". Delphi is near enough the same, but proprietary. Free Pascal compiler, and Lazarus are excellent alternatives. I highly recommend everybody give it a decent go in 2021. You might be very surprised. The free Pascal compiler is still updated to this day. So is free basic (although I haven't played with that). I've sold a couple of marketing applications I developed with Pascal and Lazarus.

@@MatkatMusic Hey weird question but what color theme are you using here? Also thanks so much for this tutorial! Currently about halfway through it working along and it's been incredibly informative.
God Bless this man, and the internet. Wonderful times we are living in.👏🏽
as an computer engineer, I never delved into much graphical C++ but not only does this look awesome, I can say that your choice of GUI really gives insight into what you're doing to the entire frequency range and would even be a cool tool for those learning about network analysis and frequency response curves for circuits! much more informative than those little sliders or pre-selected stock equalizers
^^ this me right now, but also I'm building this as a precursor to learning to build analogue synths.
I'm in EE and kinda dream of just building my own whacky things for people to geek out over.
Just started looking into audio programming last week and this pops up. Incredible. *Edit: this is a really well made and high quality tutorial. Thank you!
You're welcome!
I wish i had an attention span long enough to watch these tutorials. They look great.
lmao same
This is wild. It makes sense to a degree im a more than a newbie, but what a world to live in that we can get access to this type of material.
finally a C++ tutorial that realizes a visual project is necessary for us visual learners. THANK YOU!!!
Finally modern C++ and an interesting project.
This is an A+++ video. Thank you! I have run into a few little snags. For example, gotta know to click that button in Juce screen to open the project in xcode (as someone commented below). Also, the audioPluginHost kept crashing when I tried to scan for plugins. Just need to change the scan mode to out of process or something like that (bottom right of the screen). I am about 45 minutes into this video and loving it!!! Have been wanting to find something like this for months.
I needed this info! Thank you
Sweet Tutorial! Really fun to build out. Instead of creating 2 functions to create both the high and low pass coefficients, you can create one function and pass in a pointer to the butterworth method ie. Have a parameter juce::ReferenceCountedArray(*func)(float, double, int) and the argument would be &juce::dsp::FilterDesign::designIIR[Low/High]passHighOrderButterworthMethod
This is gonna be awesome, I love tools development especially for games. But never have a chance to use cpp. Now is the time, you are awesome dude
Thank you for checking it out!
This is great, though I can see most people still getting lost in the very verbose and exacting syntax of C++. Make sure you get a strong handle on strong typing, and understand C++ style classes, namespaces, pointers, and inhertance well or your brain will explode at some point. Expecially if you come from a scripting language background
Hi rob i am learning dsa in c++ and i can say i have a good hold of c++ if not data structures. I was looking for some projects for my resume and i don't know if these projects put off recruiters. I have no connections with my seniors since we are in a pandemic. What do you recommend? Should i build this or pass?
@@vidit9024 what kind of job you searching, in what field ?
Just a minor thing. When Projucer starts and you switch to XCode to start looking at the code, you don't show the users who've never used JUCE how to switch. You eventually do when changing the language to C++17, and then hit the icon to save and launch the IDE, but not before that. I know it is minor, but every step counts in these tutorials. There are so many bad ones out there that some users give up at the first sign of something not working or being glossed over. Having said that, I think this is going to be a great tutorial and a God-Send for me. Thank you for this :)
Thanks. I probably edited out the process of clicking that button by accident.
@@MatkatMusic Yep, I am going through the 7 day trial right now and all of the explanations are there. I definitely recommend it for new subscribers, before starting this course. The quality of the content is remarkable.
he did say the other way. you go to builds and open the xcode file in ur finder. this is one of the first things he taught.
Im using vs code and currently stuck on this part.
40:13 [Part 5] Quick Tip for VS2017 (Windows) if AudioPluginHost doesn't find your .vst4 : VS saves the .vst3 file only to its [...]\x64\Debug folder. You have one of 3 options:
1) In AudioPluginHost, add this directory when scanning for new VST3 files /
2) Copy the file by hand to a common VST3 directory (C:\Program Files\Common Files\VST3) /
3) In Solution Explorer Panel, right-click the project [PluginName]_VST3 > Properties > Build Events > Post Build and set "Command" to, for example,
[ copy /y "$(TargetPath)" "C:\Program Files\Common Files\VST3\$(TargetFileName)" ]
Attention: Post-build copy command will fail if the .vst3 file is locked (e.g. because it's currently being used by AudioPluginHost.exe)
In my Debug folder there is Shared Code folder and Standalone Plugin folder. I can't find any .vst3 file in my project. Is there some initial setup I have to do in VS for it to build this .vst3 file like do I have to install the VST SDK or is it just some setting I have to change?
@@jeremiedsouza6703 Is there a VST3 project in the Solution Explorer inside VS?
If NOT, you probably 1) made an Audio Application (make a new Projucer project and select Audio *Plugin*) or 2) unchecked VST3 in the project settings (gear icon inside Projucer > Plugin Formats). If there IS a VST3 project, you probably just need to right-click > Build it from inside Visual Studio's Solution Explorer panel.
@@nbase2652 Thank you! Yea I just had to to right click and build xD
Thank you ❤
always wondered for 5 years what plugins are after using them for guitar effects and you explained it in 5 hours. thank you
You explanation is to MAC justified,..if I'm going to pay for the class it'd be nice if you gave more info for the PC end,...I shouldn't have to decipher this myself,...all respect. This is all very intriguing and I'd like to participate if I could on Windows.
WOW WOW WOW WOW WOW WOW WOW WOW WOW WOW WOW WOW
I can't believe this. Is it real What the Hell LOOOOL Always dreamed of programming audio tools but didn't know where to begin.
This is the best thing that ever happened so far this year!!!
Thank you very much Gilfoyle
this is quite literally God-sent content to me: I've been wanting to learn more about audio plugins for months now!
🔥🔥🔥
all this is really free on TH-cam, what a time we live in! Gotta suck up as much knowledge as I can fr
Awesome tutorial.
The best part is showing the end result in the beginning before coding everything from scratch, fast forwarding code typing and the regression testing by demo.
Anything not perfect?, well on a personell matter I prefer to avoid the variable name "i" since it is so closely resembling a "1", I prefer a "n" especially in dsp-code for indexes.
and some speaker audio is sometimes doubled and even delayed, not a biggie.
and there is a cat distraction, very refreshing :-), Trixie?
Gee! Always was wondering about the approach of creating own pluggins. This course is REALLY well made and underrated
Thank you!
See, I always imagined that programmers had to program and engineer exactly how audio is converted, and what it actually is. All that stuff is underneath the implementation of it, and there does not seem to be a whole lot of designing or work at that lower level. My conception of programmers was way way off - kind of - because they did actually have to do that but it appears that those are solved problems by now, thus "standing on the shoulders of giants", but I cant shake the feeling that Im not a "real" programmer unless I get down into machine code.
On OS X Sonoma 14.2 and Juce 7.0.9 (develop branch) if you get a codesign error while building the VST3 target, make sure to Enable the "Use Hardened Runtime" option in the project's Projucer / Xcode (macOS) settings and tick the relevant "Hardened Runtime Options" then export to Xcode and build again.
I will be probably still only using the plugins, and started this course to learn the workflow/git, but man - thank you for making this tutorial!
This is an awesome tutorial. As a professional C++ programmer I am very happy that you are both refactoring code, and using template functions to do so. I am always disappointed by software developers who cannot refactor, especially in tutorials, but I see it in the professional world all the time as well, and many cannot work with template functions at all. Thank you for spreading the word about good practices in coding :)
Can u explain in layman's term about "refactoring code"? Thanks
Any other material on best practices you'd suggest checking out?
@@MonsterDAW Refactoring is the process of simplifying code by factoring out repetitions, and abstracting the code to make it more reusable. The techniques for doing this require some time and practice.
@@glitchgatsby4290 I prefer the term good practices, it is hard to judge what is best. The application of a particular practice may be good, or bad, or the best way to do something. This is somewhat subjective and depends upon the situation. There are many books that discuss best practices, and each company has its own set of them. It is hard to say what source would be good, but if you do a search for software best practices you will find many.
@@LagDaemonProgramming Thanks for the enlighten 🙏
Actually I'm not here to follow the tutorial but just to watch you writing c++ code. I just enjoy watching it. I don't know why.
Te gusta mucho C++++>
as a musician trying to learn to code, i can say this is best video i saw ever on coding topic. thank you very much
how did it go? have you been making your own plugins?
@@Thoracius 2yrs passed by and i ended up developing in typescript and node mainly, got my job in IT so yay! But no plugins yet, but ill get back to it once! 😁
“You Linux users know what to do with make file I don’t have to talk about that” - one of my proudest moments.
Hey guys, what is the alternative to the AuAudioFilePlayer in Windows? 42:34
Thanks.
Are you going to make some more tutorials about audio plugins ? That is amazing
There is something epic about this introduction and music in the background! I come back to this video every now and then just to listen to it :)
To everyone who has completed this wonderful tutorial, did anyone manged to make this part 4:37:55 ? I'm new to C++ and by reading the documentation at the hitTest() function I don't understang how this has to be done...thank you :)
Hi! Did you fix the issue? I'm running into the same thing right now.
I have had Matkat music course bookmarked on my phone forever. It's so cool to see it here on YT as well.
If it wasn't for my time constraints, I would have taken the course already. I will take it as soon as I can.
Thank you for this content!
You're welcome!
Check out the new course that I uploaded! It's a three band compressor.
Q is called bandwidth and it's units are expressed as decibels per octave or dB/oct, just the same as the slope on the low and high cut filters are. They are fundamentally the same mathematical function except the peak band has a mirrored high/low cut around it's centre frequency.
Man I'm all too excited about this video just from watching the intro!!!!!,.... I thought I was this cool guy who plays the guitar,....am I really a geek?
Oh that’s looking juicy, gonna dive in for week or so, won’t lie hope it would work when I’m finished.
Wish me and I wish you luck 🎸
How do you guys know i wanted to learn modern c++?? Thats amazing. 😂😂😂😂
This is just great. Really, thanks! I hadn't been doing any serious development since the days of Win 95, and in the mean while focused on different flavors of audio engineering. Finally set up in a decent flat with a room to spare for a home studio, and I want to DIY as much as humanly possible due to budget constraints, but, more importantly, for the sake of customization. I'm no slouch with the soldering iron & oscilloscope, but thanks to your excellent introduction to this new skill set I feel like my horizons have widened by orders of magnitude... Keep up the good work!
At 41:15 can anybody tell us what we have to do in windows as there is no option for Apple->AuAudioFilePlayer for initiating Audio input
I've been looking for something like this for very long!
Ouch this hurts a lot, i recently wanted to make a plugin as a present fo a friend who is interested in music making but i had no clue what to do so it took me a whole month to learn the basics and now this course comes out :(
u are a good friend
I am going to use it to create my own music Player!
This is great! Easy to follow. My C++ short hand needs help but I could follow this. Ty.
the mic is chandler limit. probably the best mic for CS tutorial
I'm glad someone recognized it! The mic sounds awesome! It's a shame ScreenFlow has bugs normalizing the audio when you chop up a 5hr video into 10,000 clips and produces clipping audio!!
@1:15:04 aww man I was thinking this the whole time but decided not to do it cause I was under the impression that actually using fallthrough on a switch statement was a C++ cardinal sin lmao. It makes it look cleaner definitely but I'd imagine it might make it a little harder to understand if you don't immediately notice the missing breaks.
Now I will make my own FL Studio instead of "pirating" it. 😂🤣
I thought the whole reason why FL was trash was that it was freeware. They expect people to PAY for it? lol
@@ilearncode7365 What is trash about FL?
@@ilearncode7365 FL is pretty great. It did get that reputation back when it was bundled with sound cards, though. Mostly because of it's colorful UI. Sounds like you haven't researched DAWs in a while.
I forgot to add, FL is developed in Pascal (I believe specifically Embarcadero's Delphi). Pascal is a lovely language and can do what C does. Nowadays it's called "Modern Pascal" or "Object Pascal". Delphi is near enough the same, but proprietary. Free Pascal compiler, and Lazarus are excellent alternatives. I highly recommend everybody give it a decent go in 2021. You might be very surprised. The free Pascal compiler is still updated to this day. So is free basic (although I haven't played with that). I've sold a couple of marketing applications I developed with Pascal and Lazarus.
@@jr2media635 object pascal is a great language for GUI and other types of development , it also compiles to native code !
THANK YOU FOR THIS
There aren't many good audio related coding courses.
*QuickTip* if anyone is doing this on Windows, there is another JUCE C++ Equalizer video done by MatKat where he sets everything you need (specifically at around 40:00)
ow yes, I was looking for a Juce tutorial for a long time
You're a modern day hero!
As a first year in CS, came for motivation and left with depression
Dmbfck ur in first year. Stop acting like a snowflake and learn it
welcome to impostor syndrome, youll get used to it
The app was crashing after completing around 52:00 for me. The issue was the names in `getRawParameterValue` didn't completely match the strings in `createParameterLayout`. I had a typo.
This comment helped me Thanks Bro
Cheers!
Brother man!! Thank you!! Wow.
You are one of the greatest
Just finished my plugin with this tutorial, great vids! I hope to see more free tutorials like this one :D
Can u please tell me , i just have basic knowledge about C++ will it be enough to dive n make this project? Man i need to level up my resume .
@@muskanmohabe2749 sorry i just saw this! I wouldn't recommend it to be honest if your C++ is weak since he goes pretty fast through the code and it can be easy to miss many small details!! But its not impossible if you try anyway! If you push through you will learn so much
@ 1:02:22
- may get compile error:
Conversions between enumeration and floating point values are no longer allowed
'static_cast': cannot convert from '_Ty' to 'Slope'
- i used a nested cast to resolve this error
- casting to int first
settings.lowCutSlope = static_cast(static_cast(apvts.getRawParameterValue("LowCut Slope")->load()));
settings.highCutSlope = static_cast(static_cast(apvts.getRawParameterValue("HighCut Slope")->load()));
thanks. i was wondering if i could try something like this
thaaanks maaan, you saved me!!
I'm three years late... but HELL YES!
6:50 sameeee :D Great vid btw
My producer friends will love this
There is not a lot stuff about JUCE to find,thank you.
This was an amazing project to build, definitely going to do more!!! Thank you FreeCodeCamp and MatKat Music
You are a real hero for making this video
Create a video for PySide6 and also how to compile and deploy that app.
I also want to know how desktop apps push software updates since there are a lot of dlls and other things for windows
Finally, real world C++ application with my other passion!
That beat at the start is 🔥🔥🔥
FANTASTIC !!!!!
I love C++. Coding some Voice Recognition Software here myself. Which can identify the correct waveform...
Wow...didn't expect this, amazing, thank you!!!
Amazing Job
WOW, this looks killer! Cannot wait to dive in!!!
U guys always rocksss
Wowowowowowoowowowowow im waiting for years for this Video
Worked it out now by watching the video! This plugin it really good and very well thought out - Really appreciate your efforts here SUBSCRIBED!
Thanks for watching! What do you do at Roland/Boss? Are you a hardware engineer or something? That must be a cool job!
@@MatkatMusic I was the senior electronics service engineer at Roland UK, but then set up Delatronics and eventually serviced and repaired practically all makes of electronics equipment including Fender, Yamaha, Sennheiser and Korg. I have met a lot of famous people and had a great and varied job. I had a motorcycle accident 8 yrs ago and now I have retired. I am trying to learn from you in order to maybe get another string to my bow. I am altering the colours on your EQ plugin just to try and understand how to modify, but I want to change the knob colour from purple to Ivory & I am struggling a little!
29:58 it's actually line 440 you just add // before jassert (wrapperType == wrapperType_Undefined || param->getVersionHint() != 0); and I got it to work
Dude thanks for taking the time to post this comment, MUCH APPRECIATED lol
I know what I'll be doing this weekend
when you think there´s nothing more to be done with C++, here it is an audio plugin.
separating this video to watch it later.
congrats!
thats what i want, more of these pls
WOW this is rare course, hardly you can find real world software projects in c++
lol minecraft is also built in c++
MC is written in Java,
@@janmsavage Java edition(the original) is written in Java. Bedrock edition is C++.
Guys, let's commit to one thing:
Maybe not today, but everyone watching this has to do one audio Plugin in his/her life and make it open source! Who is with me?
I'm with you. I have a ton of ideas relating to ambient music.
This is really an incredible tutorial. It's refreshing to see good code explained well.
(SOS)
1.) how to set standalone mode(Visual studio).
2.) How to load music to AUDIO plugin host(window)
Just in case someone is struggleing at 1:00:10
In the juce_FilterDesign.h file is missing the following declaration (v7.0.11):
static ReferenceCountedArray designIIRHighpassHighOrderButterworthMethod (FloatType frequency, double sampleRate, int order);
You are welcome
I was following this fantastic tutoria but I have a problem, I arrived to (0:38:55) Part 5 - Setting up Audio Plugin Host, but I am in windows and I don't have an audio player already installed. Where can I found a Juce audio player to load inside the Audio Plugin Host?
Amazing, great work!!!
MORE PROFESSIONAL C++ VIDEOS please.
this is everything ive ever wanted. thank you @Matkat Music
No way you just did this. Perfect!
amflearning by doing your tutorial so cool and awesome bro, i love it so much, it turn ourselves make an video tutorial using old and modern c++ in our channel, once again thanks alot
short nice intro and you got sub, thnx
Wow, I never thought it was this easy
