Short Convolution (Guitar Cabinet Modeling)

#21

can you share your cab impulses? or a link?

@lokki

I got a bunch from this site, though I havent converted any of them to "Axoloti format" yet:

Just let the site load. It start out with scrolling far down a site in a bit odd manner. Just let it scroll and you will get to the cab files. The ones I have checked are all random sizes, so they probably have to be stretched individually.

Also this site:

I would like to know:
1. How much is the algorithmic latency? (That is, if the impulse response were an undelayed dirac pulse, which delay value for a [delay/echo] would be equivalent?)
2. Does it only work with 16-bit resolution for the impulse response?
Thanks in advance!

  1. The current implementation has 2 samples algorithmic latency
  2. Yes, it works only with a 16 bit impulse response. The internal accumulator is 64 bit though. 32-bit resolution requires a different implementation, and would load the processor much more. I do believe that a this is an acceptable compromise in most cases.

Sorry to bring up an old thread but I'm very confused as to how you can convert a impulse response in wav format into an axoloti table.

Can someone please explain this?

Thanks
