xACT stands for X Audio Compression Toolkit. It is a GUI based front end written in AppleScript Studio for the Unix applications Shorten, shntool, monkey's audio compressor, flac, and cdda2wav with paranoia support. It also uses a modified md5sum and sox. It does the basic commands of these applications and adds a few features to speed up productivity in creation of etree.org standard filesets.
JETCURIEUX Excellent app. Concise and to the point. Makes transcoding a snap. Plus now LAME is integrated. To sum up in one word. Indespensable. (Version 1.62)
