Microphone arrays use beamforming technology to calculate the direction of sound by leveraging the time difference of arrival (TDOA) of the same sound source received by each microphone, thereby focusing on the sound from the target direction and suppressing noise.

UnverifiedSpectral mask methods typically process only magnitude information and reconstruct each stem's waveform using the phase information from the original mix, and this phase approximation introduces additional distortion when stems are heavily aliased.77% similarUnverifiedBeamforming spatially focuses on the direction of a target sound source through a multi-microphone array, suppressing noise from other directions.77% similarUnverifiedIn multimodal on-device inference, audio signals need to be converted into feature vectors via methods such as mel spectrograms, while motion data comes from the phone's accelerometer and gyroscope.76% similar
