IPP and convolution questions
-
@crd Hmm, 2.5 seconds is nothing and shouldn't cause dropouts. What machine do you use for testing and how is the buffer size / sample rate?
-
6 core Mac Pro 2013, Reaper, and 512 buffer size, 24 bit 48k.
I'll put everything through it's paces more properly tomorrow. If I don't go do xmas stuff now my family will disown me. :) -
@christoph-hart Okay I am getting the same sort of playback issue with multithreading engaged. The errors in the debug log have changed. The log is here:

The issues go away entirely when I replace the convolution reverb with the algo reverb.
-
Bump to see if anyone has any ideas about why the convolution module would be giving me these pops and clicks? Here is a wav of what is happening:
The wav file corresponds to the debug files I linked earlier.
The issue goes away when I replace the convolution reverb with the algorithmic one.

@crd Does the problem occur with any other convo reverbs?
-
@d-healey I am going to test now with some of the IR you posted on the forum a while ago and see. It seems to only happen with my largest IR (which isn't very large 2.5 sec).

No I meant have you tried the same IRs in a different convolution reverb effect?
-
@d-healey I have not. I am borrowing these IR from altiverb before I make my own but will throw them into ReaVerb later today to double check it isn't an issue with the IRs.
-
I am still having these performance issues with the convolution reverb.
Is anyone else getting pops and clicks like this?
-
@crd Did you get the same issue in another convolution reverb effect? Did you post the problem IRs in this thread?
-
@d-healey It doesn't seem to be the IR's. It seems to be a performance issue with the convolution reverb module.
-
@crd I wanted to know if you'd posted the IRs in this thread so I can test them. I've been using the convolution for years in several projects and haven't noticed any issues.
-
@d-healey I haven't posted them. I'd rather not share the specific IR's. I've tested using your hall IR and gotten the same results. It doesn't seem to be about the IR but the voice count. The issue is only happening in the compiled vst.
The pops and clicks disappear when I limit the voice count using the settings comobox, Max Voices, which is strange since my sampler's are already set to Amount, 30 and Soft Limit, 29. Good news, setting the Max Voices to 128, 64 or 32 fixes it. I'm not sure what the exact relationship is between voices and the convolution engine or the max voice setting but it's working.
