Title: paudio
Version: 0.1
Entered-date: 13JAN98
Description: paudio, or /proc/audio, is a file that
when read from, will return the data that is
currently being written to the audio device
(/dev/audio or /dev/dsp). This is useful if an
audio application doesn't allow you to save an
audio file. Note that to use this effectively,
a moderate knowledge of Linux modules is needed,
as well as a moderate knowledge of digital audio
techniques. Feel free to email me with
questions (although I gaurentee no answers!).
