Snd is a sound editor modelled loosely after Emacs. It is highly programmable, supports a variety of audio and sample file formats, includes a complete implementation of Common Lisp Music (CLM), and can be run sans GUI as a scripting engine. This script build against the Motif toolkit primarily because Snd's GTK+ interface doesn't seem as well-tested (tending to crash unexpectedly on this maintainer's x86_64 machines), but also because it supports OpenGL rendering of spectrograms. Comment out the "--with-gl" line in snd.SlackBuild if you don't want this.
