摘要： Systems, methods, and devices for processing an audio signal with two or more channels into a monaural signal are provided. For example, an electronic device configured to perform such techniques may include audio signal processing circuitry, which may receive a first audio channel signal and a second audio channel signal. Based on these signals, the audio signal processing circuitry may output a monaural signal as a sum or a difference of the first and second audio channel signals, or as a combination thereof, depending at least in part on a phase relationship between the first and second audio channel signals. Additionally or alternatively, the audio signal processing circuitry may adjust a timing relationship between the first and second audio channel signals depending at least in part on the phase relationship, before combining a proportion of the first and second audio channel signals.

摘要： Methods and devices to enable efficient beat-matched, DJ-style crossfading are provided. For example, such a method may involve determining beat locations of a first audio stream and a second audio stream and crossfading the first audio stream and the second audio stream such that the beat locations of the first audio stream are substantially aligned with the beat locations of the second audio stream. The beat locations of the first audio stream or the second audio stream may be determined based at least in part on an analysis of frequency data unpacked from one or more compressed audio files.
