While I don't doubt the calculations could be done in that time, I assumed they would still have to use the same size buffering as jack, so even if it was all done internal to one effect there would still be at least 2.67ms in the example above. 2.6ms each if they each hit jack in between. TBH, I have used my netbook as a guitar effect with 128f/p and no noticable delay. -- Len Ovens www.OvenWerks.net _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
