Codec2 Bash Scripts

Here's a bash script to round-trip a 8000Hz, 16-bit signed raw audio file through codec2. It takes the input file name and output file name as arguments:

CODEC2_HOME=/home/brucerob/codec2-2010-11-11/src
TFILE="/tmp/$(basename $0).$$.tmp"
$CODEC2_HOME/c2enc $1 $TFILE
$CODEC2_HOME/c2dec $TFILE $2

Here's a sox command to get a wav file (or whatever) into the proper raw format for codec2:

sox input.wav -r 8000 -t raw -s -2 output.raw
