ADAPTIVE MICROPHONE SAMPLING RATE TECHNIQUES |
| 摘要 |
An apparatus for adjusting a microphone sampling rate, the apparatus including an input to receive an audio signal from a microphone and a front-end processing module. The front-end processing module is to generate a plurality of frames from the audio signal received by the microphone, determine a noise profile using the plurality of frames, and adjust a sampling rate of the microphone based on the determined noise profile. |
