Audio editing software

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 save the recording
• Edit the start time, stop time, and duration of any sound on the audio timeline
• Fading into/out of or in-between audio clips.
• 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 non-linear. Each time the edited audio is played back, it is reconstructed from the original source and the specified editing steps.
