Puppy already comes with sweep installed, (v0.9.1), but I've compiled this version, (with pup2.16), in response to a query by Djof, here:Sweep is an audio editor and live playback tool for GNU/Linux, BSD and compatible systems. It supports many music and voice formats including WAV, AIFF, Ogg Vorbis, Speex and MP3, with multichannel editing and LADSPA effects plugins.

I know nothing about sweep, or it's usage, apart from knowing it's a sound editor, but was surprised that when I fired it up with a .wav file, it died with a seg-fault. Hence this attached package, which at least loads the .wav file...whether it fulfils all the other functionality is a question only users can answer.
I've only packaged as a tar.bz2 because, if you extract this to /, it will use the existing menu entry for sweep.
(N.B. oddly this version lists libtdb as a requirement, although with v0.9.1 ldd /usr/bin/sweep doesn't include libtdb. Anyway libtdb files are included with the archive)
