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： Systems and methods are disclosed for the management of memory used in a crossfading operation in an electronic device. In one embodiment, a processor is used to alternately decode two audio streams, one which is being faded out and one which is being faded in to implement a crossfade. The two audio streams may be encoded in the same or different formats and may be alternately decoded such that resource usage is reduced. The amount of decoded data of both audio streams and other parameters may determine which audio stream is to be actively decoded. In certain embodiments, the decoded data may be stored in a circular buffer, and a delta is determined between the decoded data and the empty space of the buffer.
