problems with pfft~ in m4l. hearing "crackles" everywhere.
Hi,
im just getting started with fft and the pfft~object. i wrote a little patch that sounds just nice to me -most of the time. sometimes, without changing something in the patch, just by maybe opening or closing the editor, it has a extremely annoying tremolo effect. a slow tremolo, just in the range of the framelength. i am using big frames e.g. 65536 samples. it sound as if the window-functions where out of sync and amplify each other. can this accidently happen in a pfft~?
but the much bigger problem is, when i use a small buffer like 256 samples in live, i hear crackles everywhere, when my m4l-effect is on. even when it's track is turned off. the cpu-usage is at 5% without and at 7% with the effect on. so this shouldn't be an issue, but it sounds exactly like that old problem.
thank for any advices
so.. did you experience the same issues? or is this a problem, i have with the computer or so? this is getting pretty annoying, cause i am currently using live with 512 samples minimum. at 256 samples -even before i hit the playbutton, its enough to have my effect turned on- i couldn't even use itunes, without clicks and crackles evrywhere. i think it sounds, as if they come periodicly. probably in cycles of the framesize.
please help me!
