Abstract
Methods and systems for selecting audio recording and playout sample rates for a media device so as to optimize performance of audio processing components of the device. Audio recording and playout sample rates are selected using an algorithm based on a prioritized set of factors and the particular characteristics and capabilities of an applicable audio device. The factors considered when selecting recording and playout sample rates carry an assigned weight or priority with respect to one another such that the sample rates are selected to improve the audio quality processing and performance on a given device.
Claims20
A method for selecting sample rates for audio recording and playout on an audio device, comprising:
- selecting a first recording sample rate of a plurality of recording sample rates for recording audio on the device;
- determining the device supports the first recording sample rate;
- and
- responsive to determining the device supports the first recording sample rate, selecting a playout sample rate based on the first recording sample rate.
A method for determining audio recording and playout sample rates comprising:
- selecting a first recording sample rate of a plurality of recording sample rates for recording audio on an audio device;
- determining whether the audio device supports the first recording sample rate;
- responsive to determining the audio device supports the first recording sample rate, selecting a playout sample rate based on the first recording sample rate;
- responsive to determining the audio device does not support the first recording sample rate, selecting a second recording sample rate of the plurality of recording sample rates, wherein the second recording sample rate is less than the first recording sample rate;
- and
- responsive to determining the audio device supports the second recording sample rate, selecting the playout sample rate based on the second recording sample rate.
A system for selecting sample rates for audio recording and playout comprising:
- an audio device configured to record audio using one or more of a plurality of recording sample rates and playout audio using one or more of a plurality of playout sample rates;
- and
- an audio device driver in communication with the audio device, the audio device driver configured to:
- select a first recording sample rate of the plurality of recording sample rates;
- determine the audio device supports the first recording sample rate;
- and
- in response to determining the audio device supports the first recording sample rate, select a playout sample rate of the plurality of playout sample rates based on the first recording sample rate.
