Unable to export 24 bit audio wave

[luciolepri]

I need to export from Avidemux an H264 video with a 24 bit audio wave... is it possible?
I imported the .mp4 video and the 24 bit wave track without any problem, but when I export them, without any recompression, in an AVI or MKV container, the audio is just noise...

Tryed Audacity ? It should import audio sections from video files. I don't remember if it's needed ffmpeg plugin (info and link in Audacity site).
