Reverb designs by T. Erbe

um… I did actually download it and would be happy to post it back up providing tom or uscb were happy with that… although it does beg the question of why it was taken down.

on a related note, he is also currently putting up various patches from a course he is teaching, which is a killer resource for anyone interested in pd or sound design (or both!)

the archive link on the seminar page is a 404. maybe the video is not really taken down. it’s perhaps just a technical problem ?

I sent him a message asking if it’s unavailability was deliberate and if sharing the video was ok, will report back if I get an answer.

@pxxlhxslxn Very nice patches there, thanks!

Tom replied that I should check with UCSB and just got a reply from them.

@beo figured it out, the old MAT seminar web site had to be taken down because of problems with the server and will be back up once they move to new hardware in a couple of months, so it’s only a matter of time.

Would also love to watch this! Looked around but sadly couldn’t find it anywhere else.

charlieroberts · 2019-07-13T23:17:36.092Z

I wrote the IT manager for UCSB MAT to check. I was at the original talk, but definitely would like to check it out again!

… and it’s back up! had to be converted from Flash to mp4.

That’s awesome, had totally forgotten about this, thanks!

This is great, thanks!!

@charlieroberts After seeing @qype 's comment from May I emailed the same day you did. I’m glad they followed up this time and reposted! I’ve been looking forward to watching this, especially after listening to the Art + Music + Technology podcast interview w/ Tom recently as well.

yay - does anyone know if the actual patches are anywhere ?

answer: I think this is it: http://tre.ucsd.edu/wordpress/wp-content/uploads/2016/05/pdreverb.zip

oh and slides for the visually oriented ! http://tre.ucsd.edu/wordpress/wp-content/uploads/2018/10/reverbtopo.pdf

all bases covered here

on nice he’s got max too: https://drive.google.com/file/d/0Bx0dmnQfzlhlclYzUTlzNGNYVlE/view?usp=sharing

Wow - amazing. Thanks so much for posting. I’ve been wanting to get my head round reverb in Max for a while now and this could be the base.

andrew · 2019-07-16T14:30:59.162Z

yea feel you, kinda always been intimidated by it. been wanting to take apart the convolution reverb from m4l essentials too.

voidstar · 2019-07-16T19:27:25.537Z

Not sure if it’s been posted here already, but the white paper for Erbeverb is great!

3.4 Random time modulation

The Erbe-Verb also contains a random modulation scheme which is inspired by Gordon Mumma’s piece [7] “Stressed Space Palindromes.” In this piece, the room size and shape is changing randomly and quickly from sound to sound. My scheme uses four layer granular/raised cosine envelopes on each delay line, with each grain selecting a random delay time, constrained by the modulation depth. The modulation speed is the grain creation speed. This type of modulation is effective at breaking up resonances and pulsing, without adding any chorusing or doppler shift. At extreme settings (when the modulation depth is high) it imparts it’s own characteristic sound. At a slow modulation rate one can easIily hear the space change size, and at a high modulation rate it quickly adds noise sidebands to all harmonics.

Really love this approach of taking inspiration from works, rather than other gear / established techniques.

I’m very interested in this borderline area where sound imparts reverb-like characteristics, but is not just a traditional reverb sound.

This really is one of my favourite parts of the Erbe-Verbe’s character. Just went through the video this afternoon and found it very interesting to know what was under the hood.

If it’s the same one as I’m thinking of, it is the HISS tools externals inside, so there is not much there to look at in terms of the workings. Having said that the externals are easy to use and sound great.

Wondering if a Max Reverb Studies thread would be a good idea?

andrew · 2019-07-17T13:54:25.673Z

ahhh yes this is true. could always look at the external source tho.

bradfromraleigh · 2019-07-17T14:50:01.849Z

Just wanted to say thanks to all that posted here. I unwittingly spent 3 hours last night building a reverb patch in Max and comparing my patch to Erbe’s examples, adding more components, tweaking. Then the power went out and I lost it all. Such is life… maybe the universe’s way of telling me to go to bed.

Anyway, I’m a Max newbie and this gave me just the information and inspiration I needed to sit down and make something with it.

andrew · 2019-07-17T18:12:33.990Z

definitely share whatever results come out of it ! (when power is restored)
