Hi, I have a patch that is using rfft, similar to the phase-vocoder tutorial patch. It is operating accurately and reliably until I use a large window size while have a number of instances running at once. Then I start getting crackling sounds that sound to me like audio dropouts.
When I use the cputime object, it looks like I'm well below the threshold for where I would expect problems (hovering around 20%). Activity Monitor/Task Manager shows about 20% as well, and the total cpu load is low.
I am not surprised that there are artifacts when I have too many instances of the patch running at once, but I'm surprised that it doesn't show up as cpu overrun. Are there other diagnostic tools I can use that would help me predict when I will start to hear arifacts?
