Schroeder AUv3 Reverb by Jorge Reales
https://apps.apple.com/app/id1527402838
Description:
Early Schroeder reverberators consisted of the following elements:
A series connection of several all-pass filters.
A parallel bank of feedback comb filters.
A mixing matrix.
The all-pass filters provide colourless high-density echoes in the late impulse response of the reverberator. These all-pass filters may also be referred to as diffusers. While all-pass filters are colourless in theory, perceptually, their impulse responses are only colourless when they are extremely short (less than 10 ms or so). Longer all-pass impulse responses sound similar to feedback comb-filters. For steady-state tones, however, such as sinusoids, the all-pass property gives the same gain at every frequency, unlike comb filters.
The parallel comb-filter bank is intended to give a psychoacoustically appropriate fluctuation in the reverberator frequency response. A feedback comb filter can simulate a pair of parallel walls, so one could choose the delay-line length in each comb filter to be the number of samples it takes for a plane wave to propagate from one wall to the opposite wall and back.
Thus, one may choose the comb-filter delay-line lengths more or less arbitrarily, and then use enough of them in parallel (with mutually prime delay-line lengths) to achieve a perceptually adequate fluctuation density in the frequency-response magnitude. In four such delays are chosen between 30 and 45 ms, and the corresponding feedback coefficients are set to give the desired overall decay time.

Nice one.
Sounds great with Noir.
If you want to use this with vocals, I recommend putting it in a send channel with its own LowPass filter.
Some high frequencies get exaggerated so much that even a de-esser won’t help.
Wooow. Nice little app. I literally love it😎
Any videos out there? Upcoming?
Only $0.99 which is tempting, but I gotta stop buying Fx when I need to grab TB Reverb and TB Barricade. This is me talking out loud to myself. Lol.
The description is way too technical for me.
Does this do anything the other 5-6 reverbs I own (the usual suspects) can’t do already?
@Poppadocrock same.. need to stap. btw TB Barricade is a must buy heh
A good article from ValhallaDSP about the Schroeder algorithm.
https://valhalladsp.com/2009/05/30/schroeder-reverbs-the-forgotten-algorithm/
"The reason this is notable is that real rooms and acoustic spaces have an echo density that increases with time, while the parallel combs and series allpass reverberators have a constant echo density. By placing the allpasses in a feedback path, a much more natural reverberation decay is created."
"The idea of putting allpasses inside of delayed feedback loops is fundamental to the algorithms of Lexicon, Alesis, and other high end reverberator manufacturers, and is still used to this day."
I for one am a complete reverb nerd and love having a new one come out that isn't tainted with a 'shimmer' algo.
Yes but it costs $1 to find out what that might be and it will be different for each of us.
This is from the developer that had the rough launch of his "OB-Xd AUv3 synth" ($7) which has since gotten stable. He also has a simple scope app for $1.
Indeed, been holding off on those 2 TB apps for way to long. I’m basically on the verge of getting them, since it’s pay day. Hooray.
I feel this is the kind of Reverb that divides people into those who like it and those who don’t.
Personally I like it and put it in the same ’category’ as the Ratshack Reverb from AudioDamage
I like it. Somehow it doesn’t give me the retro vibe Ratshack reverb did. But it’s a long time since I tried that and this one has to be tested more.
And it is just plain simple!!
I quite like it too, it’s a bit raspy, dirty and simple...
I always really appreciate Jorge's prices. Sure the interfaces of the synths, the preset browsers etc could use some work, but they sound great and are good value for money. Haven't tried this yet, but am definitely intrigued.
That‘s the simple side of the coin - the other is the tricky and complex implementation to make it sound good or even great.
seconded 200%
Just a quick visual comparison between Ratshack and Schroeder (thanks to Blue Mangoo) will show that the response is very different
Great. I'm going to get a lot of use out of this oscilloscope.
What’s wrong with ApeMatrix’ own oscilloscope?
To be honest, I have completely forgotten about this oscilloscope from ApeMatrix that is excellent too. Here is a comparison with another Schroeder response (that is very artistic on its own)
Those are beautiful lines. Very artistic. Maybe blue mangoo’s is more visually appealing? Could be used to make the visuals to a track.
It doesn’t do spectrogram
Ok, thanks.
What do you think this kind of reverb sounds good on, folks? It definitely seems to have some lingering notes that might sound good in the right context or might be jarring otherwise.
I’m enjoying it on my Dixie sequencer so far...
Are you using it with low decay times or high? Definitely if I do high I get a lot of a kind of one note feedback sound, but if I don't put the decay high, it's quite thin.
Yeah keeping it quite mellow as it does seem to get out of hand quite easily
Hard to put a finger on it but I'd say very experimental stuff.
The frequencies go all over the place so it's more like an untamed beast of some kind?!
@Samu with higher decay settings I'm getting absolutely BRUTAL digital clipping. Is that the way this kind of reverb behaves or might that be some kind of bug?
I think it's by design or something?!
We'll see what happens, lately the developer has been pretty quick to fix issues if they are actual issues and 'not by design'
I've emailed Jorge so I'll see what he says. Thnx
Here's my walkthrough on OPL and also the Schroeder reverb
