#!/bin/sh
# Shell script to record sound files from unix style sound devices.
# Should auto detect most supported systems and record the file for you.
#
# Originally developed by Chris Bagwell (cbagwell@sprynet.com)
#
# Change History:
#
# June 1, 1998 - Chris Bagwell (cbagwell@sprynet.com)
# Kjetil Torgrim Homme <kjetilho@ifi.uio.no> sent in a neat patch to
# attempt an educated guess on how to rec sound on sun hardware.
# There is probably a better way to do it in the actual software though.
#
# Use the parsed out volume flag to have sox change the volume. Yes, its
# better to use the audio devices hardware mixer to adjust volume but some
# way is better then no way. Its still parsed seperately so people may
# optionally pass the parameter to a mixer.
#
# September 7, 1998 - Chris Bagwell (cbagwell@sprynet.com)
#
# Updated usage checking a little more so that only one filename can
# be given.
#
# January 9, 1999 - Chris Bagwell (cbagwell@sprynet.com)
#
# Quoted $filename so that files with spaces in their names can
# be given.
# Arnim Rupp patch file to work with multiple sound devices via
# command line option.
#
# Set up path so that it can find Sox if user's path doesn't already
# include it.
