Abstract
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.
