Why you cannot capture Reverb Pedals?

Quad Cortex

Hi all

I got a stupid question. Why you can not capture reverb pedals with the QC? I mean the technology is there for convolution reverb, with a frequency sweep and all. Is this due to to the modulation or pitch of certain pedals? As a first step to capturing reverb, wouldn’t it be cool to get a test frequency within the QC to capture room reverbs (convolution)?

Cheers

The QC cannot capture any time based effects. No current capturing technology will capture time based effects etc.

Yeah i got that but WHY?

Assuming they would also need to develop a convolution reverb device and software for the device to create an impulse response for it. Probably more involved than they would want.

But could be cool!

A lot of time-based effects captures are HUGE files, digitally, so they don’t make sense to use as captures but rather to just reproduce in software versions. A solid reverb IR would be like 10x the filesize of a cab IR, for example.

Digital reverbs are massive, complicated algorithms that change at every point along the decay of the reverb in terms of EQ, volume, density, etc. There’d be no way to accurately “capture” this with a static setting of the target reverb. They’re not just a filter that the sound passes through like a drive or amp. They’d be more like a filter feeding into a filter feeding into a filter … feeding into a filter, each with variables adjusted for each iteration.

I’m sure someone will eventually make it happen, but I suspect it would take active participation on the user’s behalf, following instructions (now, turn the decay all the way up. Now, turn the mix all the way up, etc.)

Interesting idea, though!

Digital reverbs have been recreated with IR’s for many years now actually. Plugins such as this have existed since the mid 2000’s - https://www.sweetwater.com/store/detail/Altiverb8--audio-ease-altiverb-8-convolution-reverb-plug-in-download

Yes the convolution reverbs exist for a long time now. I am not speaking about adjusting the decay or any parameter. I talk about a static IRs of a Room. I get that is too complicated with modulation and such.

The QC is locked at 21ms (or so) for IRs = 1024 samples @ 48khz.
21 ms is way too short for a reverb IR (even a simple room reflection).

…sadly
