fft size limits for pfft

July 8, 2012 | 9:36 am

this doesn’t seem to be documented, and I was wondering if there are any hard limits to the fft size argument in a pfft object

I’ve used 16384 and it seems to work– also interested in the other extreme– but I guess 8 or 16 would be the practical limit

it does not say anything.

FYI, I just used 32,768 in an experimental scenario (i.e. not really a finished patch, so no UI or other things that might impact practical performance) and it was no problem. I probably could have been able to push it a little further. For my interest, I’ve found much larger sizes than seem to be typically used produce a much more useable result, so It’s worth experimenting with.
