Subject: Bug#179764: 8-bit audio samples incorrectly played back
Package: xmms-flac
Version: 1.1.0-3
All flac packages {flac, libflac4, xmms-flac} are Debian Sid release
1.1.0-3. xmms is Debian 1.2.7-1.1 .
When decoding from an 8-bit sample resolution audio file (8-bit .wav
-> .flac), the audio upon playback is severely clipped; heard, as
well as seen with visualization plugins. The problem persists even
with --no-replay-gain given to the encoder, and is present in both
mono and stereo audio files. Sample rate (eg, 11khz, 22khz, 44khz)
seems to be irrelevant.
16-bit flacs are played back properly.
flac -d (to decode) writes a properly-scaled .wav as expected.
steps in brief:
assuming "snd_8.wav" is, for example, a 44100 stereo 8-bit Microsoft
WAV (PCM) file...
1. flac snd_8.wav
produces snd_8.flac
2. flac -d -osnd_8_2.wav snd_8.flac
outputs: snd_8_2.wav, from snd_8.flac
3. xmms -e snd_8.flac snd_8_2.wav
snd_8.flac waveform-clips severely, but snd_8_2.wav plays fine
