mpg321 doesn't convert mp3 to wav properly

[adamdaughterson]

Hi. The command that I am using is:

mpg321 -b 10000 -s songname.mp3 | sox -t wav -r 44100 -s -w -c 2 - songname.wav

mpg321 seems to create the file, but it is not creating the RIFF header properly. The error output is "sox failed reading -: WAVE: RIFF header not found.
Also when I try to open the file using any multimedia app (XMMS, grecord, etc...) the errors are the same. Is there something I am missing? There don't seem to be a great deal of references on Google about mpg321, does anyone know where there might be good examples of it working to perform mp3 to wav conversion?
cheers,

Everything is as it should. The thing is that mpg123 doesn't create WAV files; it creates raw files (ie. no header at all). Also, no buffering is necessary when just converting, so just run this instead: "mpg123 -s song.mp3 | sox -t .raw -r 44100 -sw -c 2 - output.wav".
(Hint: mpg321 is aliased to mpg123, and mpg123 is more common, since it's the name of the original application. You might have known that, I just mentioned it in case you didn't.)

Ahh... I see. I was trying to pass a *.wav to sox, but it was just the datastream. That makes sense now. Thank you for you tip!
