On any ARC cluster, check the installation details
by typing "module spider sox".

SOX requires that the appropriate modules be loaded before it can be run.
One version of the appropriate commands for use on NewRiver is:

module purge
module load gcc/5.2.0
module load sox/14.4.2


The following batch file takes a 20 second recording of Bach and extracts
a 10 second clip starting 5 seconds from the beginning.

#! /bin/bash
#PBS -l walltime=00:05:00
#PBS -l nodes=1:ppn=1
#PBS -W group_list=newriver
#PBS -q open_q
#PBS -j oe
module purge
module load gcc/5.2.0
module load sox/14.4.2
sox bach20.wav bach10.wav trim 5 10
