Abstract
A method and apparatus are described for aligning cross-faded audio signals using beats. In an embodiment, a controller includes a cross-fade module having at least first and second audio inputs and an audio output port to provide an audio output signal to an external audio reproduction system. A control signal determines whether to provide the first or the second audio signal to the audio output, and the cross-fade module cross-fades the audio output signal from one audio signal to the other audio signal. A beat alignment module determines a delay between a first beat of the first audio signal and a second beat of the second audio signal, and a delay module delays either the first or the second audio signal to compensate for the delay into the cross-fade module.
