Abstract
This disclosure describes techniques that include aligning processing of audio samples collected by multiple audio sensors or microphones. In one example, this disclosure describes a method comprising detecting a transition by the second microphone from a disabled state to an enabled state; after detecting the transition, performing phase alignment between audio samples collected by the first microphone and audio samples collected by the second microphone by introducing a delay in starting processing of the audio samples collected by the second microphone; and processing the phase-aligned audio samples.
Claims18
An artificial reality system comprising a first microphone, a second microphone, and an audio processing system, wherein the audio processing system is configured to:
- detect a status change associated with the artificial reality system requiring a more robust audio processing;
- responsive to detecting the status change, initiate a transition of the second microphone from a disabled state to an enabled state;
- detect a transition by the second microphone from the disabled state to the enabled state;
- after detecting the transition, perform phase alignment between audio samples collected by the first microphone and audio samples collected by the second microphone by introducing a delay in starting processing of the audio samples collected by the second microphone;
- and
- process the phase-aligned audio samples.
A method comprising:
- detecting, by an audio processing system in an artificial reality system having a first microphone and a second microphone, a status change associated with the artificial reality system requiring a more robust audio processing;
- responsive to detecting the status change, initiate a transition of the second microphone from a disabled state to an enabled state;
- detecting, by the audio processing system, a transition by the second microphone from the disabled state to the enabled state;
- performing, by the audio processing system and after detecting the transition, phase alignment between audio samples collected by the first microphone and audio samples collected by the second microphone by introducing a delay in starting processing of the audio samples collected by the second microphone;
- and
- processing, by the audio processing system, the phase-aligned audio samples.
A non-transitory computer-readable storage medium comprising instructions that, when executed, configure an audio processing system of an artificial reality system to:
- detect a status change associated with an artificial reality system requiring a more robust audio processing, wherein the artificial reality system includes a first microphone and second microphone;
- responsive to detecting the status change, initiate a transition of the second microphone from a disabled state to an enabled state;
- detect a transition by the second microphone from the disabled state to the enabled state;
- after detecting the transition, perform phase alignment between audio samples collected by the first microphone and audio samples collected by the second microphone by introducing a delay in starting processing of the audio samples collected by the second microphone;
- and
- process the phase-aligned audio samples.
