Patent ID: 11395065

Abstract:
An audio device, an audio system, and an audio processing method that implement noise (echo) cancellation techniques are provided. The audio device includes a primary microphone(s) that is arranged closer to a desired sound source and configured to collect first audio signals containing more of target audio signals. In addition to the primary microphone(s), an auxiliary microphone(s) is arranged away from the desired sound source and configured to collect second audio signals containing less of the target audio signals. A microcontroller is configured to process the first audio signals and the second audio signals to generate a data stream. An encoding scheme(s) is implemented in encoding the audio signals, optionally with to-be-played audio signals outputted to a loudspeaker, into the data stream. At least one multi-input audio processing algorithm(s) is applied to the data stream to arrive at an accurate interpretation and/or comprehension of the audio signals or an improvement of human-to-human voice communications.
