Smack My Batch Up is a
software tool for generating new sounds by
processing old ones with VST plug-ins. The
processing is automated so you can leave it running
(once it has been set up) leaving you free to go and
do other things. You can give it a folder of sounds
and it will pass each one in turn through the
effects and record them back onto your hard disk,
ready for when you get back.
Smack My Batch Up is available as a
free download for Windows or Mac.
