I was mixing my project, no longer needed to track anything, so I raised the buffer size to lighten the load on my CPU.
Something sounded not quite right and I narrowed it down to metalizer insert effect I had placed on an fx track…
Changing the buffer size on my audio interface (Tascam US-16x08) changes how the metalizer effect sounds…I was under the impression that once everything is in the box, the buffer size should not have any effect on the sound?? (well, technically I know the buffersize is used by the vst effect code but the point is that it shouldn’t affect the sound if it’s coded properly)
I’ve attached an example:
1st segment original sound.
2ndst segment is buffer size @ 128 samples (oddly, this sounds ok here once I export the track but it sounds different/broken on live playback within project)
3rd segment @ 1024 samples
4th @ 2048 samples.
One can clearly hear the difference.
is it broken? Anyone have a good explanation as to the artifacts?
