> fixed it, should be working now. I translated your program into C, ran it, and get a nice constant vibrato. If you want to have a look (if you read C): http://pastebin.com/pJKA10Ub It spits floats, the 2s of vibrato followed by the 2s with no vibrato. You can compile: gcc ex.c -lm then run ./a.out | aplay -r 44100 -f FLOAT_LE (it works on my x86_64 computer, it should work on any little endian thing, I guess) I tried your python version and get weird results. I don't know what's wrong. Translating line by line into C gives a nice vibrato... weird... Sorry, I can't help more. > > > https://gist.github.com/3815747 _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
