I’m fairly sure that you meant to say “Shimmer reverb” there. That’s OK, I understand, we all make mistakes sometimes. Shimmer reverb. Yes. It could be Massive.
One step at a time… First an algorithmic reverb, second an auto-leveler in the same vein as the “Jünger Audio Level Magic”, third a LUFS meter with one-click conforming to peak, momentary max, short-term max or program loudness, and then…drum-roll…a shimmer verb.
I’m not particularly knowledgeable in this area, but audio blogs say that reverbs that aren’t convolution, don’t use impulses and instead calculate reverb internally are called algorithmic
This tutorial shows how to make something like that. The pitch shift is at the beginning of the effects chain, not in the feedback loop. I thought that was what you meant at first, but if an octave shift was in the feedback of a delay it would shift out of audibility in just a couple of loops through the delay wouldn’t it? In any case this particular flavor puts the pitch shift first, then
pitch shift->reverb->delay->EQ
Doesn’t seem too difficult to build up in that form.
That doesn’t have the feedback loop to the reverb.
The idea is that you keep sending a progressively more pitch shifted signal through the reverb.
You can fake similar results without the feedback loop (one trick I’ve seen done with Live is two reverbs stacked on either side of the pitch shift/delay units) , but it’s not actually the same thing.
I keep thinking that I should add a shimmer algorithm to Dragonfly Reverb. From what I can tell it doesn’t seem too hard to do… but… aren’t we getting off topic here? This thread is about the LSP Plugins release.
I’m pretty sure that you cannot build this with separate digital effects running at a large block-size. You even run into unwanted side-effects if you do a feedback loop with 1 cycle delay in a modular, apart from that, digital pitch-shifters usually introduce latency.
I also expect you need a rather high quality pitch-shifter, too. Perhaps LSP can provide that one day.
