Audio mixing

A process or technique used to combine a number of recorded sounds, such as speech, atmosphere, sound effects and music, into one or more tracks. Usually, the intention is to blend the sounds in such a way as to create the illusion that they were all recorded together.

Nowadays, most audio mixing can be done using specialist computer software called a Digital Audio Workstation (DAW).

Effects such as reverb and delay can be added using plugins, particularly when mixing music. Processors can change the audio signal, causing sounds to ‘fade in’ and ‘fade out’, or altering dynamics and frequency at various points. Background noise and a musical soundtrack can be added.

Audio tracks can be mixed in mono, stereo or surround sound. Mono creates a single channel of sound, stereo is designed to be played back by two speakers (left and right), whereas surround sound uses a larger number (usually five, although it can incorporate sixteen or more), and creates a more three-dimensional environment.

Live audio mixing can be done while a performance is actually taking place, for example at a concert.
