I have a large number of .RAW audio files (unsigned 8-bit PCM with no-endianness) which I want to convert to .WAV files. What command-line tool (windows or linux) can I use
MPlayer should be able to convert your audio;
$ mplayer \ -quiet \ -vo null \ -vc dummy \ -af volume=0,resample=44100:0:1 \ -ao pcm:waveheader:file="file.wav" "file.raw"
It's available in most linux distributions package managers.
