I use the following script to perform compression and normalization on e-mailed voicemails. I put the script in as /usr/local/bin/sox and pre-pend /usr/local/bin to the PATH before asterisk runs in the startup script.
The values for the compressor are not scientific, I monkeyed with them until I thought it sounded like a good volume, YMMV. Daniel #!/bin/sh # # $1 = -v # $2 = number # $3 = inFile # $4 = outFile # REALSOX="/usr/bin/sox" if [ "$1" != "-v" ]; then $REALSOX $* exit $? fi INFILE="$3" OUTFILE="$4" # # Perform the gain adjustment. # $REALSOX "$INFILE" "$OUTFILE" compand 0.1,0.3 -60,-60,-30,-15,-20,-12,-4,-8,-2,-7 0 0 0.2 On Jun 26, 2009, at 7:44 AM, Adam Moffett wrote: > We generally get our voicemails emailed to us from asterisk, but some > people's messages are extraordinarily loud or quiet.
