I mean, if, for example, ALSA buffer length is 1024, and FFT lengthis 8192, then 7 of 8 ALSA buffers the plugin is ding practically nothing,just copies data into input FFT fifos, and after the 8-th ALSA bufferFFT is lauched for every of the 6 channels. So, the CPU load is quite uneven. ... Well, the above is almost true - due to oversampling FFT is launchedrather every 4 ALSA buffers, not every 8, which means twice the load,but more evenly distributed, but still, uneven. If you can, try to play with ALSA buffers at system level - forthe case of 8192 length FFT I'd suggest 4096 samples long ALSA buffers,so FFT will be performed upon arrival of every ALSA buffer, and CPUload will be even. And I do not know how to change ALSA buffers length at systemlevel - to tweak asound.conf ? Or to create .asoundrc in your home dir and set buffer lengths in it ? > Best regards,> Sebastian> --Sergei. P.S. Since a bug was found and fixed, I'm thinking about a followuprelease, and the example of mbeq_119700 has just proved yet anothertime that developers can not be trusted testers when it comes to testingtheir own stuff, so, will you help me testing the next release ? I think that the Perl part you've apparently used to configure theplugin will remain the same - the pieces intended for configuration,I mean. So it will hopefully won't take long to configure and test. -- Visit my http://appsfromscratch.berlios.de/ open source project. -------------------------------------------------------------------------Take Surveys.
