Is there a command line tool for Windows 7 or Linux that given an m3u file, converts each file into one long file in a given format?

I have looked at avconv but it seems like it does not have this option. All files are wave audio file

The easiest way to do this is to take a player that can output to stdout and then have sox read from stdin and convert appropriately.

mpg321 -s -@ playlist.m3u | sox -t raw -r 44.1k -e signed -b 16 -c 2 - output.mp3
