Abstract: Systems and methods are described for enhancing the audio quality of an FM receiver. In embodiments described herein, a stop band noise signal is extracted from an L+R or L−R signal produced by an FM stereo decoder. A channel quality measure is calculated based on the stop band noise signal and is used to control whether a pop suppression technique is applied to the L+R signal. The channel quality measure and the stop band noise signal are also leveraged to perform single-channel noise suppression in the frequency domain on the L−R signal and on the L+R signal. The channel quality measure is also used to control the application of a fast fading compensation process that replaces noisy segments of the L−R and L+R signal with replacement waveforms generated via waveform extrapolation.

Abstract: Methods, systems, and apparatuses are described for improved multi-microphone source tracking and noise suppression. In multi-microphone devices and systems, frequency domain acoustic echo cancellation is performed on each microphone input, and microphone levels and sensitivity are normalized. Methods, systems, and apparatuses are also described for improved acoustic scene analysis and source tracking using steered null error transforms, on-line adaptive acoustic scene modeling, and speaker-dependent information. Switched super-directive beamforming reinforces desired audio sources and closed-form blocking matrices suppress desired audio sources based on spatial information derived from microphone pairings. Underlying statistics are tracked and used to updated filters and models. Automatic detection of single-user and multi-user scenarios, and single-channel suppression using spatial information, non-spatial information, and residual echo are also described.

Abstract: Methods, systems, and apparatuses are described for determining relative locations of wireless loudspeakers and performing channel mapping thereof Δn audio processing component utilizes sounds produced by wireless loudspeakers during setup/installation procedures, which are received by a microphone at locations in an acoustic space, to determine an amount of time between when the audio signal is initially transmitted and when the microphone signal is received. The audio processing component also utilizes wireless timing signals provided by a wireless transceiver, at locations in the acoustic space, to wireless loudspeakers and then back to the wireless transceiver to determine an amount of time between transmission and reception by the wireless transceiver. The timing delays are used to determine the locations of the wireless loudspeakers in the acoustic space. Based on the determined locations, the audio processing component generates indications of correct or incorrect wireless loudspeaker placements, and performs audio channel mapping.
