The sox7.linux.tar.Z contains sox 7.0 adapted to play and record sound files under Linux. sox is a program for converting sound files between several formats such as .au, .snd, .voc and .wav. To use the recording and playback feature under Linux, create the following symbolic link: ln -s /dev/dsp /dev/dsp.sbdsp Playing is possible by using the /dev/dsp.sbdsp as the output file. For example sox sound.wav /dev/dsp.sbdsp The sox7.linux.tar.Z contains the complete source. If you already have the sox 7.0, you may use the sox7.linux.diff to patch your own copy. Sox is created and maintained by Lance Norskog (thinman@netcom.com). I have just adapted it for Linux (see sox7.linux.diff). Hannu Savolainen hsavolai@cs.helsinki.fi
