Hi Romain,
I do the test with a simple script:
audio = audio_to_stereo(single("/tmp/test.wav"))
output = output.icecast(%mp3(bitrate=128), host = "127.0.0.1", port = 8000,
mount = "audio", audio)
first I tried with a 32khz mono wav file -> bad sound quality
Then I resample the original audio file with Sox ("sox test.wav -r 44100
testSox.wav"), and I run the same LS script with the new Sox file -> good
quality
These are the logs for the resample version

Could also paste the next lines? We should see something like:
2012/02/04 16:16:28 [audio.converter:4] Using libsamplerate converter
You need to set log level to 4:
set("log.level", 4)
