Julien send me a MP3 of a modern pop song, so I guess the MP3 did reach 0dbFS, I didn't check it and I already deleted the file. However, it can't be more than 0dBFS, so I expect that at 100% it should be +- 0dB and shouldn't cause clipping. If you push it up to > 100% than clipping would cause distortion, that's ok. However, IMO something is fishy, if I need to decrease it to around 90%. I've got meters provided by hdspmixer. -- Install pulseaudio, don't use jack http://lists.alioth.debian.org/pipermail/d-community-offtopic/2013-March/000195.html _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
