Mark has written a great bpm scanner:
bpm-tag (C) Copyright 2012 Mark Hills <firstname.lastname@example.org> Usage: bpm-tag [options] <file> Tag an audio file with tempo (in beats-per-minute, BPM) -f Ignore existing BPM value -n Display BPM only, don't tag -m Minimum detected BPM -x Maximum detected BPM -h Display this help message and exit
The bpm-tag script in bpm-tools works on one file at a time.
To batch tag in the current directory do this:
find ./ -type f -print0 | xargs -0 -n1 bpm-tag
If you want to scan annother directory replace
./ with the folder you want to scan.
If you have a multicore machine try this, it will run 4 instances in parallel:
find ./ -type f -print0 | xargs -0 -n1 -P4 bpm-tag
