#!/bin/sh# Shell script to play sound files to unix style sound devices.# Should auto detect most supported systems and play the file for you.## Originally developed by Chris Bagwell (cbagwell@sprynet.com)##   TODO:  Put each set of fopts and filenames on an array and then #          play each filename back with the given effect.h## 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 play 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.## Set up path to sox so that it can find it if user's path doesn't already# include it.PATH=$PATH:/usr/local/binexport PATHhelp(){  echo "play v1.4 - front end to Sox"  echo ""  echo "Usage: play [ fopts ] infile [effects]"  echo  echo "fopts: -c channels -h -r rate -t type -v volume -s/-u/-U/-A -b/-w/-l/-f/-d/-D -x"  echo  echo "effects: avg/band/chorus/copy/cut/deemph/echo/echos/flanger/highp/lowp/map/mask/phaser/pick/polyphase/rate/resample/reverb/reverse/split/stat/vibro"  echo ""  echo "See sox man page for more info on required effects options."}if [ "$1" = "" ] ; then  help; exit 1;fiwhile [ $# -ne 0 ] # loop over argumentsdo case $1 in   avg|band|chorus|copy|cut|echo|echos|flanger|highp|lowp|map|mask|phaser|pick|pred|rate|resample|reverb|reverse|split|stat|vibro)     effects="$@"     break     ;;   -c)     shift     fopts="$fopts -c $1"     ;;   -h)     help;     exit 1;     ;;   -r)     shift     fopts="$fopts -r $1"     ;;   -t)     shift     fopts="$fopts -t $1"     ;;   -v)     shift     volume="-v $1"     ;;   -)     filename="-"     ;;   -*)     fopts="$fopts $1"     ;;   *)     if [ "$filename" = "" ]; then       filename="$1"     else       echo "Filename already give.
