BTW, this actually works for me. I can see the 19 kHz tone with all models from 0 to 4, created as such: > ffmpeg-20140908-git-f044fc0-win64-static\bin\ffmpeg.exe -f lavfi -i > "sine=frequency=19000:sample_rate=48000:duration=5" -c:a libtwolame -psymodel > 4 test.twolame.p4.mp2 Using model "-1", I see no tone though, just like with ffmpeg's native mp2 encoder.
