Same distribution, same vlc-version, no clipping (checked with jkmeter). made a test file with a 30 Hz sine, range -1...1, in 16 bit wav format. generated in pd, recorded with $ jack_capture --bitdepth 16 --channels 2 --port system:playback_1 --port system:playback_2 30Hz.wav At 100% volume in vlc, jkmeter shows a peak value of -0.0, just as expected. Needless to say, but also jaaa/my ears didn't exhibit any indication of clipping-induced HF content (which clearly shows up at >100%). During the journey, I found in vlc: Tools -> Preferences -> Audio -> Replay Gain mode. That one should probably be set to the default 'none'. best, d _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
