Audio editing software is any software or computer program which allows
editing and generating audio data. Audio editing software can be
implemented completely or partly as a library, as a computer
application, as a web application, or as a loadable kernel module.
Wave editors are digital audio editors. There are many sources of
software available to perform this function. Most can edit music, apply
effects and filters, and adjust stereo channels.

Audio editing software typically offer the following features:
The ability to import and export various audio file formats for
editing.
Record audio from one or more inputs and store recordings in the
computer's memory as digital audio.
Edit the start time, stop time, and duration of any sound on the
audio timeline.
Fade into or out of a clip (e.g. an S-fade out during applause after
a performance), or between clips (e.g. crossfading between takes).
Mix multiple sound sources/tracks, combine them at various volume
levels and pan from channel to channel to one or more output tracks
