Abstract
A device includes a memory buffer configured to store additional audio data during a reduced power state. The device also includes audio processing circuitry configured to operate in accordance with the timing criteria of a voice call by alternating between a processing enabled state during a first time period and a reduced power state during a second time period. During each processing enabled state, the audio processing circuitry is configured to obtain audio data from the memory buffer in shared memory of the device, concurrently process the audio data and voice data obtained from a microphone and associated with the voice call, and generate output audio based on the audio data and the voice data.
Claims17
A device comprising:
- a memory buffer configured to store additional audio data during a reduced power state;
- and
- audio processing circuitry configured to operate in accordance with timing criteria of a voice call by alternating between a processing enabled state during a first time period and a reduced power state during a second time period;
- wherein, during each processing enabled state, the audio processing circuitry is configured to:
- obtain audio data from the memory buffer in shared memory of the device;
- concurrently process the audio data and voice data obtained from a microphone and associated with the voice call;
- and
- generate output audio based on the audio data and the voice data.
A device comprising:
- a memory buffer configured to store additional audio data during a second time period;
- and
- audio processing circuitry, coupled to the memory buffer, and configured to transition between
- (a) a processing enabled state during a first time period recurring according to timing criteria of a voice call, and
- (b) a reduced power state during a second time period defined by the timing criteria;
- wherein, while in the processing enabled state, the audio processing circuitry is configured to:
- obtain audio data from the memory buffer of the device;
- process, during the first time period, the audio data concurrently with voice data obtained from a microphone and associated with the voice call;
- and
- generate output audio based on the audio data and the voice data.
