#!/bin/bash
# ./menu.sh
#
# David Rowe
# Created August 2009
#
# Presents a menu of sound files, press 1 to play file1, 2 to play file2 etc
#
# The aim is to make comparing files with different processing easier than
# using up-arrow on the command line. Based on cdialog.
#
# usage:
# menu.sh file1.raw file2.raw ........ [-d playbackdevice]
#
# for example:
#
# ../script/menu.sh hts1a.raw hts1a_uq.raw
#
# or:
#
# ../script/menu.sh hts1a.raw hts1a_uq.raw -d /dev/dsp1
