Teensy Digital Delay using ADC and DAC
ฝัง

- Using the Teensy Audio Design GUI, let's make a digital audio delay effect with around 2 seconds of delay using internal memory, and potentiometers to control delay time and delay feedback gain.
Experiments include a sound sample stored in memory for quick testing with a button trigger and an ADC input to test with an mp3 player.

Brilliant! I may need to get one of these Teensy devices.
This is a great channel, thank you!
awesome video! it’s really nice to see the teensy 3.6 fritzing graphic i designed being put to good use :)
That fritzing part has been very helpful! I forget where I found it, I always just Google for parts not already in the libraries. Thanks for creating it!
Gadget Reboot i love fritzing for its ability to create breadboard views! it makes a project so easy to understand. it’s really nice to see your diagram :) keep on the great work with the excellent videos :)
Thank you for this video sir.. It help me a lot to understand my teensy 3.2 😊..
Helpful information. İ like your video
Fantastic! Just what I was looking for. After spending the last week trying to get a PT2399 wired up (epic fail) looks like this will do the same thing with a lot more flexibility and a lot less fiddling around with weird size capacitors and resistors. Thanks for all your hard work and sharing it with us.
Funny you should mention that, sometime soon I will be trying to get PT 2399 working. Maybe I should be scared! I don’t remember what kind of component values were needed but I may not have them and I may have to order stuff. I guess that means more mail bags!
You prolly dont care at all but does anyone know a method to get back into an instagram account??
I was stupid forgot the login password. I would love any tips you can give me.
@Orlando Wesley instablaster =)
@Dorian Marley Thanks so much for your reply. I found the site thru google and im in the hacking process atm.
I see it takes a while so I will reply here later when my account password hopefully is recovered.
@Dorian Marley It worked and I finally got access to my account again. Im so happy!
Thanks so much, you saved my ass!
great
Very interesting. Is it possible to create a sort of instant replay using this type of setup? Say you're listening to a radio station and someone says "what did they just say?", you could press the button and have the last 10 seconds of audio play over again. I would imagine you would need to store the audio in a circular buffer that is large enough to store 10 seconds worth of audio. You would always be recording so the circular buffer would always have the latest 10 seconds of audio in it. The output would be the live audio until the button was pressed, at which time the recorded 10 seconds would then replay. That would be really cool.
External memory can be added for longer storage and then it sounds like it would be straightforward enough. people add external memory for guitar effects projects.
Does it use flash memory for buffers? How long it would take to wear out the memory if u use this kind of unit as a everyday on-board effect?
Just want to make my own reverb effect pedal for my guitar😅
That's pretty rad but it takes the fun out of doing it on a circuit level without code. Well if you're into electronic music. The teensy would be cool to use as a multieffect. The 4.1 can have up to 16 gb of ps ram I believe. Too bad they've tripled in price. I regret not buying one. It'll be cool when we have sbc boards that enable us to make something like a neural dsp haha
How well does it block dc in the on board filter?
I still need to get a PT2399 echo circuit wired up, have the parts, now need the time. I also wanted to try analog chorus or flange with separate chips for A/D, D/A, memory.
I think it's been a year and a half since I used Teensy so I can't remember much but don't recall anything problematic. I've been dabbling with ESP32 and I2S audio as well so I'm all over the place.
@@GadgetReboot its crazy how people keep exploiting the different feature sets in that risc v chip. If they had paid for a couple more logic blocks for floating point units in the substrate the sky would be the limit eith them. Cool stuff man. Keep it up. Experimenting with different things is great ehh
I would like to build a delay for control voltage signals. Can I discuss somehow with you.
Remind me again: why haven't I started with my Teensy? :)
Speed soldering takes up so much time with all the training requirements... There’s barely any time left over for any other projects!
@@GadgetReboot I should do some slow soldering then!
Can you stop using new chips and boards in you video's. Now i'm going to have to get one of these boards to play with. :)
Your channel is giving too many things to do :) keep the output coming i'm sure I'll find the time to keep up.
Yeah I think I bought this module at least three years ago if that makes any sense I’m not even sure when it came out and it was sitting around for probably a year and a half before I even touched it so now I’m playing catch-up! Luckily I can’t afford to go out and buy a whole bunch of other new modules so we are all safe from more diverse content on here!
Hello sir maybe you could make a video tutorial of freeverb on teensy 3.2.. Im a newbee so hopefully you could make one, to help more newbee like me 😊.. Thank you again sir..
I will see if I can make it work
@@GadgetReboot thank you so much for making the freeverb video tutorial genius sir.. 😊 your channel is a big help for us newbee 😅

@Bramskee Balag this sketch works for the freeverb. The input and output are the same as shown here: github.com/GadgetReboot/Teensy_Digital_Delay/blob/master/Teensy_Delay_Schematic.jpg
