Abstract: An apparatus and method for speech communication is described. An audio transmit processor captures at least two audio signals from an audio source, and processes the at least two audio signals to provide a mono audio signal and a non-audio signal comprising spatial information representative of the direction of the audio source. The audio transmit processor combines the non-audio signal with the mono audio signal by watermarking; and transmits the watermarked audio signal. An audio receive processor receives a watermarked audio signal and extracts a mono audio signal and a non-audio signal comprising spatial information from the watermarked audio signal. The audio receive processor processes the mono audio signal and spatial information to generate at least two output audio signals.

Abstract: FM and AM receivers in car environments require a noise blanker circuit or method to reduce the audible disturbances generated by impulse noise, such as ignition noise, in the audio signal. The invention proposes a combination of time-domain and frequency-domain processing to reduce the audible distortion. The time-domain processing interpolates the signal during the impulse noise bursts, and the frequency-domain processing disperses the remaining signal distortion over time, or relocates it to positions in time where it is attenuated by a windowing technique.
