Audio editing software is software which allows editing and generating of audio data. Audio editing software can be implemented completely or partly as library, as computer application or as a loadable kernel module.

A digital audio workstation (DAW) can consist to a great part out of software. are usually software suites composed of many distinct software components, giving access to them through a unified graphical user interface using GTK+, Qt or some other library for the GUI widgets.

Audio data can be characterized as digitized audio signal, cf. digital audio.


For use with music[edit]

Editors designed for use with music typically allow the user to do the following:

  • 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
  • Apply simple or advanced effects or filters, including compression, expansion, flanging, reverb, audio noise reduction and equalization to change the audio
  • Playback sound (often after being mixed) that can be sent to one or more outputs, such as speakers, additional processors, or a recording medium
  • Conversion between different audio file formats, or between different sound quality levels

Typically these tasks can be performed in a manner that is both non-linear and non-destructive.

For use with speech[edit]

Editors designed for use in speech research add the ability to make measurements and perform acoustic analyses such as extracting and displaying a fundamental frequency contour or spectrogram. They typically lack most or all of the effects of interest to musicians.
