BEAMFORMING FOR A MICROPHONE ARRAY BASED ON A STEERED RESPONSE POWER TRANSFORMATION OF AUDIO DATA - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240381025 titled 'BEAMFORMING FOR A MICROPHONE ARRAY BASED ON A STEERED RESPONSE POWER TRANSFORMATION OF AUDIO DATA
The patent application describes techniques for providing beamforming for microphone arrays based on a steered response power transformation of audio data.
- Receiving audio data from multiple audio capture devices, including at least one microphone array within an audio environment.
- Generating a steered response power transformation of the audio data, which includes a set of weights for a spatial coordinate grid representing the audio environment.
- Performing beamforming steering or beamforming selection based on a signal-to-noise ratio estimate associated with the steered response power transformation for the microphone array.
Potential Applications: - Audio processing in smart devices - Speech recognition systems - Noise cancellation technology

Original Abstract Submitted
techniques are disclosed herein for providing beamforming for at least one microphone array based at least in part on a steered response power (srp) transformation of audio data. examples may include receiving audio data from multiple audio capture devices comprising at least one microphone array located within an audio environment. examples may also include generating an srp transformation of the audio data. the srp transformation may comprise a set of srp weights for a spatial coordinate grid representing the audio environment. examples may also include performing, based at least in part on a signal-to-noise ratio (snr) estimate associated with the srp transformation, one or more of beamforming steering or beamforming selection with respect to the at least one linear array microphone.
