Abstract
A music and audio playback system enables an operator to control an audio effect for transitioning an audio output signal from a first audio source to a second audio source by using a single cross-fader control. The transition audio effect combines the two incoming sources using a function that depends on the current position of the cross-fader control. Effects include cross-fading the frequency range, band-ducking, vocoder effects, and beat-cutting effects. The technique is especially advantageous in DJ performance systems in which audio effect-based transitions can add excitement and variety to a performance. Dedicated transition effect preset buttons located near the cross fader facilitate rapid selection by the DJ of the cross-fader controlled transition audio effect.
