Really great video! The biggest difference between the 301 and 361 are the fact that the time constants are the same with all bands with the 301, but with the 361s the two top bands are different, faster I believe. The second biggest difference is the 301 uses germainiums while the 361 uses FETs. Folks with these units and all the subsequent aftermarket hardware and plugins overlook that there are really great uses with decode as well. It can be a fantastic expander and fixative tool. Try it on an overly compressed drum bus, or as a way to bring life to a boring Ableton loop
Check out this bit from an old SOS article on the making of REM’s Murmur, super clever use by Don Dixon I would guess. "For some reason, Bill played his hi‑hat really loud in those days, and when we got into the tracks we realised it was everywhere. Hi‑hats can be like that - we even had hi‑hat in the bass drum, way beyond what we could handle. So, we started doing some really funny things with Bill's drums, like decoding the mic input through a Dolby A unit as a sort of high‑frequency dynamic expander. This got the hi‑hat out of the bass drum, and although it was heavy‑handed, it worked.”
Right on! There’s Dolby options inside of Universal Audio’s Sound City Studios plugin, a favorite effect (when not used for NR!) by house engineer Keith Olsen. We were able to borrow his 301 and 361 units for study!
I used to engineer at Maison Rouge in London and was lucky enough to record my bands tracks in studio down time. We'd recorded a track on one weekend, then came in the next to mix. Only problem was the studio had hired out all the Dolby SR modules we'd used to record. Can't remember why we had to mix that weekend but I said maybe I could do something with the track on the SSL with some filtering and gating. The sound of the track was virtually out of control, all the expansion and hf boost you're talking about. But it gave the track an energy and a liveness that really worked! I'm trying to remix that track now (in the box) and it just doesn't have the same energy... So I'll be looking for a solution to replicate that undecoded Dolby effect somehow...
@@cristouk That’s a great story about how an obvious problem becomes the magic! Maybe grab a Dolby plug-in and parallel it on…. …everything? Might be reckless, but also might be fun!
@@davidpetersmusic I've tried a few things to recreate it, the closest I got was the Uhe Statin plugin which lets you encode a track and turn decode off (Dolby A sim). Not quite the same - the Dolby SR without decode "pumped" more IMO. If I don't find anything it's almost worth hiring a studio for day and printing everything with Dolby off.
What an incredibly delightful video. Absolutely the best video I've seen on the Dolby trick, and I'm so happy to see that you did it with two versions of the original hardware and those super awesome looking standard audio stretch devices. It's almost impossible to find a Dolby trick video using the actual hardware in a way that's not just a playthrough of a little bit of program material. Instead you have us a full expose of the history and the considerations and the possibilities. It took me two years to finally find a Dolby 365 and get some cool mod cards. It's such a delightful device, really great to see that that Stretch device is able to capture so much of the original! Thank you so much for this. It's literally a perfect TH-cam video, and is what this platform was created for.
One of the best education and demonstration videos I have seen. The A/B comparisons as well realtime adjusting controls while playing tracks were clearly audible and connected to your explanations perfectly. I loved the lizard and the humour (kudos to your animator😊). Thanks for sharing your knowledge and the work that entails ✌🏻
I found this video researching the Dolby A301 and how to get that sound! This is officially the most informative resource on the internet about it. Subscribed. I would love to see more videos like this that teach us about the technology of yesteryear and how to use these techniques in a modern setup! It beats the heck out of these other channels that mostly review new gear/plugins. I really like the learning aspect of this.
I live for feedback like this! Thank you very much. That is one of the goals of these videos, to cover the uncovered and unique. If you haven't already, check out the Level-Loc video. It's very similar. I'm also about to start working on a video all about running things through vintage transformers. Stay tuned.
@@davidpetersmusic I totally understand that. I produce videos for a living and I'd love to start a channel, I just never seem to have enough time to get something up. Thanks for sharing what you can. I love your approach. You've got a great vibe.
Acoustic guitars on some Eagles records were done this way, one track normal, one track with EnCoded Dolby A, blend to-taste,. It brights out brightness on the low-level stuff while keeping back brightness on anything loud.
I didn't know that! ...but it makes sense. I like a touch of the dolby on things like finger-picked acoustics, mandolins, etc unless they were tracked overly bright. But a ribbon mic plus a little dolby can be quite nice.
@@davidpetersmusic I dug a little bit online... S.A. declares the Stretch "inspired by modified noise reduction units from the 1970’s and 80’s"... I understand 361, rather than 301...In fact in your video the 301 has such a vibey sound to it (maybe overloaded?) that the other two units simply don't have. Thanks again for the great test!!!
Brilliant! JUst by happenstance I stumbled on your channel and love your approach and vibe. Being a somewhat "age-challenged" audio engineer, I have used the Dolby units for the exact purpose you demoed. Found out about this in the 90's from one of Mutt's techs, and you are indeed correct in regards to his use of the same. Great demos. I look forward to hearing more from you.Peace!
@@brucema12 Glad you stumbled in! If used well, age simply becomes wisdom. I’d rather be age-challenged than wisdom-challenged! Thanks for the comment and support.
Just discovered your channel, subscribed after the first few minutes. Love the concept of "misusing" bits of equipment in a creative manner, versus just reaching for the latest "flavour of the month" plugin.
Thanks! I'll be misusing another piece of kit in the next video as well. All of these are well-established misuses, but that shouldn't stop us from searching for new ones!
@@davidpetersmusic Completely agree. I often misuse DSP algorithms for interesting audio effects. An example, the Dolby dBx A and B NR systems used in the 70s and 80s, I have a pretty good approximation as a plugin I wrote and have made provision for variable de-emphesis. It can go from completely over the top and sibilant to a more gentle setting of just adding some "air" to a track or mix.
How strange the universe can be. I was randomly thinking, “man, a comprehensive video on the Dolby Noise Reduction technology would be super interesting”. There isnt a lot out there that breaks it down in a technical way. With Dolby Atomos, it got me thinking about Dolby as a company and how long they have been around. That was just a few days ago. Then bam! You release this video. How cool. Absolutely love your setup there by the way. Great choices
My favorite piece of studio kit is the implant I put in your brain! But really, thank you, I sincerely appreciate the appreciation. I was thinking the topic might already be covered more than enough, but I noticed there was no demo of a 301 or the Stretch. I should do a video on those studio choices. They took a long time to figure out.
That's awesome. If you are interested in making some quick bucks, let me know what your rate is and I'll be glad to send some kick, snare and tom stereo stems and full drum mix. I would love to mix those back in parallel to my projects.
Great video. This was a fairly standard technique in film and TV for dialogue for years. Many dub stages in LA had a kind of DIY rig with a small fader box patched up to a card cage. Really great on soft spoken voices. Easy to over do…
Thanks! I think I included a photo of one of those boxes you mentioned with the card cage, but I didn't remember it was a film-centric thing. This is why TH-cam can be fun, collecting additional insights!
Afaik, in film there was a commercially available regular product called Dolby Cat43A, that was this fader box mentioned. It was not DIY. Anyhow, many people built something similarly for themselves, surely.
Such a killer piece of hardware, the software versions aren't too bad too. Slate Digital came out with something similar in their Virtual Mix Rack but I feel it's a bit overcooked compared to the hardware units displayed in this video. As you mention, it's very easy to overdo :D It's like an instant 'that sounds nice' button and you can get carried away. Amazing content, high quality, sharing your knowledge in a digestible manner. Keep up the great work David!
Very interesting! There was a Dolby system, though newer than these versions, on the Studer in the studio were I interned a million years ago. Man, I wish I could have seen the faces the owners would have made if I tried experimenting with it in this manner! I have the Waves Abbey Road Saturator plug-in, and it seems to do a similar sort of thing. Just discovered your channel tonight in my studio and man, this is the type of stuff TH-cam really lacks as far as production and engineering for many genres of music. Keep it up!
Thanks for watching and for all the support. I'm trying to cover the less-covered stuff. The videos take a long time so I feel I should make them count!
Very nice! Does this also work with DBX noise reduction units? Incidentally, back in the day, some musicians, producers and engineers preferred DBX to Dolby because DBX worked across the whole frequency spectrum. Vangelis was noteworthy for having DBX units in his Nemo Studio, which can be verified on the Nemo Studios website. However, he did use Dolby A for the final stereo master after the multitrack DBX tapes had been decoded. Apparently he liked the sound the DBX units gave his recordings.
AudioThing Type A is one of them. There are more out there I'm sure. I use a 361 patch on the Acustica Audio Nebula platform often. I'm not sure if that's still available out there though.
Great video. Next up could be the history of the Aphex Aural Exciter. I own two of the mid-earlier units, being the Broadcast II. Afaik there were at least two models before these, each sounding quite different. The earliest had a tube amp stage!
Great video, I've been a fan of the Gem Audio Dopamine for years. Please do a walkthrough of how to get those settings on your MB compressor to get the sound.
@@KevinSimpson031 Thanks! It’s hard to know exactly what Dolby was doing in there, but if I wanted to approximate a 361 I believe the crossover points are 80Hz, 3k and 9k. I’m not sure how much they boosted them or the attack/ release settings, though I believe they are quite fast. However, I’m not sure the exact settings are the important thing. It’s more about the concept. Boost highs on a multi-band compressor, compress them aggressively, then blend to taste in parallel. It doesn’t need to sound just like the old units to be a successful approach.
I just winged it on the ProMB examples. I think the Dolby units crossover at 80Hz, 3k and 9k. If you search the internet a little you might find the approximate curves of each band. I think you can create your own settings to taste though! Just push some level and compress anywhere 3k or higher. The basic idea is simply blending in compressed high end.
Interesting side fact: the Dolby 360 and 361 frame that holds those actual Cat-cardriges, has a significant influence in the units overall tone. I've got both, and whilst they only differ slightly in circuitry, they deliver very different HF tonality when swapping the Cat22 card between them. Might be a combination of silghtly different output transformer plus different PSU?
Agreed! The Input and Output stages in each chassis has a big influence on the tone, and the tone influences how each blends in the mix. It might seem subtle on the surface, but in context you really notice it.
@@davidpetersmusic yes very much so. I’m going to pick up the standard audio stretch because of your demo. I was looking into the 361s but with the added features of the stretch (and blend control) I have found what I’ve been looking for. Thanks.
@@Glasside These strings were recorded almost 15 years ago now. I did this particular arrangement myself and it was played by a quintet of fantastic LA film score players. I’m in the middle of remixing this collection for release in the coming months. LOTS of strings all over it, and some of them arranged by people who are far better arrangers than I am! Access to players like these has been one big benefit of LA.
The original Dolby units that use Dolby B I think. Are they worth modding or trying this trick.i have two. One is for a two track tape deck or reel to reel. The other is for an eight track.
@@kellymichael9567 I wish I had experience I could share but I’ve never used Dolby B in this way. That said, I’m guessing all the units do some version of the same thing. You can always try plugging in a Dolby B unit and just encoding with that and see if you like it. I often use mine with no mods, so it’s just like plugging in anything else.
Hi! If you mean "original" in the style of the 301 as seen in David's video, I had a chance to pick one up years ago but it did not work the way the 301 does. According to the manual, its principle of operation is different. But hey... give it a go. You might like what it does.
What a great video! And you released it almost the same time with the new tape-emulation plugin from AirWindows (it's free and from independent developer), which has built-in flexible encoding-decoding stages of his variation of Dolby system. So it was nice to hear these real life examples of actual hardware units in this context, as well as your thoughts on it. I'm new to your channel, and seem like it's really great! Subscribing:)
Another excellent post, David, I'm impressed with all the vintage Dolby hardware you assembled to compare, what a sonic and visual treat. Audio tools never cease to amaze me, and this was a new angle with nice results. The trick reminds me a little of the Aphex Aural Exciter, which were originally designed to add sparkle back to analog tape that had lost some luster. I'm surprised there isn't an Aural Exciter in your studio yet, would love to hear your take on those.
@@JackNance22 I have never tried an Aural Exciter here! …or at least it’s been a long time. I have a goal of reducing my setup as much as I can without compromising what I can do and also doing as little processing in the box as possible. Simplicity is my new ‘thing’, but it’s a complicated journey to pull all that off!
@@davidpetersmusic I hear you on reducing setup. Vintage Aphex gear can sell for super cheap and sounds awesome, that's why I still buy it. It's my only hardware that says "Made In Los Angeles" on it too, I dig that;)
I think the 363 uses the "SR" processing cards instead of the "A" processing. Being newer, the SR was probably better for noise reduction, but maybe not as cool as an outboard effect. ...but, I've never tried it!
@pb3662 just chiming in here as a total non-expert who's had the SR and 22 cards for just a few weeks. It seems that only the 22 cards are typically modified; the 22 ones that I have are switchable modified so that you can click in and out the various Dolby tricks amongst the bands. But the SR cards that came with this 365 are not modified, and I don't really see any information about modifying the SR cards in the same way that the 22 cards are modified. I have played through the SR cards and in my decidedly inexpert opinion they sound like a more sophisticated and polished version of what David played through with his unmodified Cat 22 card. I actually *really* like the SR effect blended in parallel, it seems to bring up detail but not squash the perceived dynamic range as much as the Type A Cat 22 cards.
You should absolutely try the sr cards, they are amazing on drums, i actually prefer them than the cat22 cards for drums, in parallel obv cause they're quite drastic! Got the a301 too, love it too.
@@davidpetersmusic Cat No 300 modules are both SR/A selectable by a toggle switch and work in the 363 chassis. I tend to use mine for their designed purpose but have experimented in the past. The A is useable but the SR I find to artifacty.
@@stubbadubs I just guessed on the ProMB settings to roughly illustrate visually what’s happening. I believe the Dolby A crossover points are 80Hz, 3k and/or 9k. The compression also seems pretty fast and aggressive. Think of it as regular parallel compression but with only the highs active and boosted.
@@davidpetersmusic Fostex B-16 for Dolby C and my studio partner reminded me we got the E-16 soon after and that the Dolby S was a lot better and breathy. We never told anyone we’d used it. I learned it from a studio course with Dolby A for “air” and iirc he learned it from someone who worked with John Fryer of NIN etc notoriety
@@Blackgreywhitegold Sounds like the Dolby process itself was pretty consistent and could do the same basic job across revisions. Perhaps just the curves, crossovers, number of bands, etc, were adjusted over time.
@@analoguewings That trick became pretty common in the day I imagine. But also, you can pin the highs on an EQ when you’re working with tape and get away with it a lot more.
I even think this trick was used on almost everything pop/rock in the 1970s - the top studio scene is pretty small and engineers and producers had an incentive to get top notch results every time - it was big money. All this 70s bubble gum pop has some of it for sure. I was thinking if regular multiband compressor wouldn’t give similar results wit lower bands disengaged.
I think you could definitely get similar results out of parallel multi-band compression on the top bands! I almost included that, but it just ended up being too much for one video. Part of the magic in the Dolby units is the audio transformers, especially in the big 301. That that shouldn't stop you from using the concept with any multi-band, hardware or software!
great video! would be interesting to hear the same source material through a plug in version (gem dopamine or pro-mb?) vs the hardware. when doing my own comparisons, some hardware v software differences are negligible while others not at all (e.g. level-or v devil-loc). not in to cut into the sponsorship $ dolby is giving u (haha, i make joke). much love!
I agree! I did actually have some of that in the video initially but it got too long and complicated and direct comparisons were a challenge with level matching, etc. That said, the ProMB can do a nice job at consistent top end, but lacks the particular flavor (if you dig it). I've never tried the Dopamine plugin but I do have Nebula captures of the 361 which I've used a lot and like.
So many people I meet say they know someone who looks just like me! I've even had people stop me thinking I was someone they knew. Have you ever watched the early 2000s remake of Battlestar Galactica? I could be a Cylon copy.
Really great video! The biggest difference between the 301 and 361 are the fact that the time constants are the same with all bands with the 301, but with the 361s the two top bands are different, faster I believe. The second biggest difference is the 301 uses germainiums while the 361 uses FETs.

"Crispy" is a good word for it, especially if using the mod version.
Nice work.
Thank you much! Trying not to suck at these.
Excellent video, big like
@@Zenvo-uu9tm Big thanks in return!
What are these PlugIns that does that trick would be very helpful to know…. Thanks…👍
AudioThing Type A is one of them. There are more out there I'm sure. I use a 361 patch on the Acustica Audio Nebula platform often. I'm not sure if that's still available out there though.
Hey thank you so much for answering so quickly! Good video as well ! Thank you so much 🙋🏻♂️🎈🐺
Keep going man! Loving your channel
It all depends on how many more dragons my kid is willing to animate! ;-) Thanks for the channel love. More to come!

Great video. Next up could be the history of the Aphex Aural Exciter. I own two of the mid-earlier units, being the Broadcast II. Afaik there were at least two models before these, each sounding quite different. The earliest had a tube amp stage!
I've never owned one or even heard one! Perhaps I can find one to borrow. I'm borrowing for the video I'm working on now, and I'm glad I did!
awesome stuff david!
@@fastpeak Thanks! I’m so happy it’s landing!
Great video, I've been a fan of the Gem Audio Dopamine for years. Please do a walkthrough of how to get those settings on your MB compressor to get the sound.
@@KevinSimpson031 Thanks! It’s hard to know exactly what Dolby was doing in there, but if I wanted to approximate a 361 I believe the crossover points are 80Hz, 3k and 9k. I’m not sure how much they boosted them or the attack/ release settings, though I believe they are quite fast. However, I’m not sure the exact settings are the important thing. It’s more about the concept. Boost highs on a multi-band compressor, compress them aggressively, then blend to taste in parallel. It doesn’t need to sound just like the old units to be a successful approach.
Very cool, never knew about this! Would love to grab those proQ presets 😅
I just winged it on the ProMB examples. I think the Dolby units crossover at 80Hz, 3k and 9k. If you search the internet a little you might find the approximate curves of each band. I think you can create your own settings to taste though! Just push some level and compress anywhere 3k or higher. The basic idea is simply blending in compressed high end.
I have the Dolby Spectral Processor 740. Is that similar?
I have no idea! That's a new one to me!
I liked the ''Sever-en'' joke so I subscribed
This is my new favorite reason to subscribe. I appreciate it!
Interesting side fact: the Dolby 360 and 361 frame that holds those actual Cat-cardriges, has a significant influence in the units overall tone. I've got both, and whilst they only differ slightly in circuitry, they deliver very different HF tonality when swapping the Cat22 card between them. Might be a combination of silghtly different output transformer plus different PSU?
Agreed! The Input and Output stages in each chassis has a big influence on the tone, and the tone influences how each blends in the mix. It might seem subtle on the surface, but in context you really notice it.
Awesome video! ❤
Glad you liked it!!
@@davidpetersmusic yes very much so. I’m going to pick up the standard audio stretch because of your demo. I was looking into the 361s but with the added features of the stretch (and blend control) I have found what I’ve been looking for. Thanks.
Very cool! The easy presets and blend knob make them very effective indeed.
Overloud Dopamine is a very good plugin emulation.
I shall check it out!
Virtual Mix Rack by Slate Audio has an emulation of the 361!
Have you checked out Gem Dopamine plugin? I think it's emulating the Dolby 361
I have not had a chance to hear it yet. I have used an Acustica Nebula patch of the 361 I liked a lot though.
Where did the music with the strings come from? It was nice.
It's a song of mine I'm re-releasing soon called Flags. Thanks for asking!
@@davidpetersmusic May I ask who wrote/played the strings? They sound great
@@davidpetersmusic Song sounds wonderful by the way
@@Glasside These strings were recorded almost 15 years ago now. I did this particular arrangement myself and it was played by a quintet of fantastic LA film score players. I’m in the middle of remixing this collection for release in the coming months. LOTS of strings all over it, and some of them arranged by people who are far better arrangers than I am! Access to players like these has been one big benefit of LA.
Nice video. Thanks for all the hard work. Is that unit mono? so if you wanna use it on mixbus or something, you will need 2 unit?
Thanks! The 361's and Stretch units are each mono, but I have two of each in the video. The big A301 is two channels.
@@davidpetersmusic 🙏
thank You!
Thank YOU!
The original Dolby units that use Dolby B I think. Are they worth modding or trying this trick.i have two. One is for a two track tape deck or reel to reel. The other is for an eight track.
@@kellymichael9567 I wish I had experience I could share but I’ve never used Dolby B in this way. That said, I’m guessing all the units do some version of the same thing. You can always try plugging in a Dolby B unit and just encoding with that and see if you like it. I often use mine with no mods, so it’s just like plugging in anything else.
Hi! If you mean "original" in the style of the 301 as seen in David's video, I had a chance to pick one up years ago but it did not work the way the 301 does. According to the manual, its principle of operation is different. But hey... give it a go. You might like what it does.
What a great video!
And you released it almost the same time with the new tape-emulation plugin from AirWindows (it's free and from independent developer), which has built-in flexible encoding-decoding stages of his variation of Dolby system.
So it was nice to hear these real life examples of actual hardware units in this context, as well as your thoughts on it.
I'm new to your channel, and seem like it's really great! Subscribing:)
Big thank you! This is the second comment about the fortunate timing of this video. The stars must be aligning in Dolby-World!
What's the plugin from AirWindows called?
@@TheAzurefang ToTape7
And also he has Dolby as a separate plugin if you don't need other features, it's called Dubly2.
@@TheAzurefang toTape7
Another excellent post, David, I'm impressed with all the vintage Dolby hardware you assembled to compare, what a sonic and visual treat. Audio tools never cease to amaze me, and this was a new angle with nice results. The trick reminds me a little of the Aphex Aural Exciter, which were originally designed to add sparkle back to analog tape that had lost some luster. I'm surprised there isn't an Aural Exciter in your studio yet, would love to hear your take on those.
@@JackNance22 I have never tried an Aural Exciter here! …or at least it’s been a long time. I have a goal of reducing my setup as much as I can without compromising what I can do and also doing as little processing in the box as possible. Simplicity is my new ‘thing’, but it’s a complicated journey to pull all that off!
@@davidpetersmusic I hear you on reducing setup. Vintage Aphex gear can sell for super cheap and sounds awesome, that's why I still buy it. It's my only hardware that says "Made In Los Angeles" on it too, I dig that;)
I've always been impressed when I heard the vintage Aphex stuff.
Can you provide any more info on the Dolby 361 vs 363 please?
I think the 363 uses the "SR" processing cards instead of the "A" processing. Being newer, the SR was probably better for noise reduction, but maybe not as cool as an outboard effect. ...but, I've never tried it!
@pb3662 just chiming in here as a total non-expert who's had the SR and 22 cards for just a few weeks. It seems that only the 22 cards are typically modified; the 22 ones that I have are switchable modified so that you can click in and out the various Dolby tricks amongst the bands.
But the SR cards that came with this 365 are not modified, and I don't really see any information about modifying the SR cards in the same way that the 22 cards are modified.
I have played through the SR cards and in my decidedly inexpert opinion they sound like a more sophisticated and polished version of what David played through with his unmodified Cat 22 card.
I actually *really* like the SR effect blended in parallel, it seems to bring up detail but not squash the perceived dynamic range as much as the Type A Cat 22 cards.
You should absolutely try the sr cards, they are amazing on drums, i actually prefer them than the cat22 cards for drums, in parallel obv cause they're quite drastic! Got the a301 too, love it too.
@@beyondgrooveproductions Great insight on the SR, I’ll have to try that!
@@davidpetersmusic Cat No 300 modules are both SR/A selectable by a toggle switch and work in the 363 chassis. I tend to use mine for their designed purpose but have experimented in the past. The A is useable but the SR I find to artifacty.
Wow, best video on Dolby processor ❤
Thank you, sir! Pete the Dragon gets all the credit though.
do you have the PRO MB presets perchance? best
@@stubbadubs I just guessed on the ProMB settings to roughly illustrate visually what’s happening. I believe the Dolby A crossover points are 80Hz, 3k and/or 9k. The compression also seems pretty fast and aggressive. Think of it as regular parallel compression but with only the highs active and boosted.
Wait🤔 So they used OTT in the 70's too?! 🙃😋
Used Dolby C for vocals too
@@Blackgreywhitegold Interesting. Is there are particular machine you used?
@@davidpetersmusic Fostex B-16 for Dolby C and my studio partner reminded me we got the E-16 soon after and that the Dolby S was a lot better and breathy. We never told anyone we’d used it. I learned it from a studio course with Dolby A for “air” and iirc he learned it from someone who worked with John Fryer of NIN etc notoriety
@@Blackgreywhitegold Sounds like the Dolby process itself was pretty consistent and could do the same basic job across revisions. Perhaps just the curves, crossovers, number of bands, etc, were adjusted over time.
@@davidpetersmusic B to C was a big jump in character. Tapeheads is probably a good source for graphs and ratios. The info you seek is out there! :)
Pete should be an industry standard
@@mhdighermuntazar Everybody needs one!
Anyone know if Ace Frehley used the dolby trick on vocals? His vocals on Kiss songs have this really cool toppy but not harsh sound
@@analoguewings That trick became pretty common in the day I imagine. But also, you can pin the highs on an EQ when you’re working with tape and get away with it a lot more.
I even think this trick was used on almost everything pop/rock in the 1970s - the top studio scene is pretty small and engineers and producers had an incentive to get top notch results every time - it was big money. All this 70s bubble gum pop has some of it for sure. I was thinking if regular multiband compressor wouldn’t give similar results wit lower bands disengaged.
I think you could definitely get similar results out of parallel multi-band compression on the top bands! I almost included that, but it just ended up being too much for one video. Part of the magic in the Dolby units is the audio transformers, especially in the big 301. That that shouldn't stop you from using the concept with any multi-band, hardware or software!
Wow, RCA 44 + A301 without the card is istant john lennon's Alan White drums
There ya go! It's a fun sound.
It sounds compressed and brighter, lol.

Many thanks! More stuff to come as time allows.
great video! would be interesting to hear the same source material through a plug in version (gem dopamine or pro-mb?) vs the hardware. when doing my own comparisons, some hardware v software differences are negligible while others not at all (e.g. level-or v devil-loc). not in to cut into the sponsorship $ dolby is giving u (haha, i make joke). much love!
I agree! I did actually have some of that in the video initially but it got too long and complicated and direct comparisons were a challenge with level matching, etc. That said, the ProMB can do a nice job at consistent top end, but lacks the particular flavor (if you dig it). I've never tried the Dopamine plugin but I do have Nebula captures of the 361 which I've used a lot and like.
@@davidpetersmusic check out gem it's cool. never had the chance to compare to real hw hence my interest :)
Be cool to hear Overloud’s Dopamine plugin compared to these
That's been a popular request. I have not heard it yet myself. I do have an Acustica Nebula patch that works pretty well.
@@davidpetersmusic what's the name of this patch?
