The Sound-Recorder/Editor utilities (also called SoundEdRec) are graphical front-ends (GUI's) for existing sound utilities that are already present on most Linux PC's. Although everything could be done from the command-line, it is often helpful to have a tool like Sound-Rec/Ed to accomplish frequently-repeated command-combinations by merely pressing buttons. The Sound-Editor tool also provides some visual editing capabilities. SoundRecEd's initial configuration defaults to commonly available record, playback, and conversion tools. It is easily configured to use any alternative tools that you prefer.
Without SoundRecEd, you could record audio from a live event using the ALSA arecord function on the command-line. At some point you may wish to pause the recording. Or, you wish to split the recording into separate files by resuming recording into a new sequentially named file. However, it would take some time to manipulate the command-line to do this. In the meantime, you miss incoming material, and/or accidentally overwrite an existing file. At the same time, to conserve disk space, you may wish to initiate conversion to OGG or MP3, followed by deletion of the WAV file. The Sound-Recorder GUI will do all these things automatically by pressing buttons: record, stop, pause, split,... record, etc., similar to using a tape-deck.
