mhwaveedit (edit, play, and record sound files)
mhWaveEdit is a graphical program for editing, playing, and recording
sound files. It is lightweight, portable, user-friendly, and handles
large files very well.
The program itself has only simple editing features such as cut'n'paste
and volume adjustment, but it can also use Ladspa effect plugins and
the effects provided by the SoX application. It can also support
additional file formats besides wav through libsndfile and mp3/ogg
import and export through lame and oggenc/oggdec.
lame, jack[*], and portaudio are optional dependencies.
[*] If jack support is included, this package uses POSIX filesystem
capabilities to execute with elevated privileges (required
for realtime audio processing). This may be considered a
security/stability risk. Please read http://www.slackbuilds.org/caps/
for more information. To disable capabilities, pass SETCAP=no to
the script.
