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, methods, and devices for noise profile determination for a voice-related feature of an electronic device are provided. In one example, an electronic device capable of such noise profile determination may include a microphone and data processing circuitry. When a voice-related feature of the electronic device is not in use, the microphone may obtain ambient sounds. The data processing circuitry may determine a noise profile based at least in part on the obtained ambient sounds. The noise profile may enable the data processing circuitry to at least partially filter other ambient sounds obtained when the voice-related feature of the electronic device is in use.

摘要： Various techniques relating to the buffering of a live audio broadcast on an electronic device and the subsequently playback the buffered data are provided. In one embodiment, the playback speed of the buffered data may be increased relative to the actual speed at which the data was originally broadcasted. If the buffered playback (using the increased playback speed) synchronizes or catches up to the live broadcast, the electronic device may disable buffering and output the live stream instead. This decreases processing demands by lowering processing cycles required for buffering (encoding, etc.) and playback of the buffered data (decoding, etc.), thereby reducing power consumption.

摘要： An embodiment of a system to synchronize data streams is described. During operation, the system receives a first data stream having a first data type and performs a sequence of operations on at least a portion of the first data stream. Next, the system stores metadata associated with the first data stream one or more times during the sequence of operations. Metadata can include a time stamp, data-stream information associated with the portion of the first data stream, and event information associated with the occurrence of one or more events during the sequence of operations. Moreover, the system provides a notification based on the stored metadata, the notification to facilitate synchronizing the first data stream with a second data stream having a second data type.
