Audio device and audio processing method

An audio processing method, comprising:

• connecting an audio device to a computing terminal, the audio device including at least two microphones and a plurality of sampling ports each corresponding and connected to one of the at least two microphones;
• obtaining audio signals collected by the at least two microphones of the audio device;
• sampling the audio signals collected by the at least two microphones at the plurality of sampling ports in parallel;
• encoding, by the audio device, the audio signals sampled at the plurality of sampling ports using an interleaved encoding scheme to generate one data stream, the plurality of sampling ports being triggered by a same clock signal to ensure an accuracy of alignments of decoded audio signals based on the data stream in a range of a microsecond order;
• and
• sending the data stream to the computing terminal, the datastream being decoded and processed by the computing terminal to perform an action.

An audio system, comprising:

• an audio device, and a computing terminal,
• wherein:
• the audio device includes:
• at least two microphones configured to collect audio signals, a microcontroller connected to the at least two microphones, and a plurality of sampling ports each corresponding and connected to one of the at least two microphones;
• the microcontroller is configured to:
• sample the audio signals collected by the at least two microphones at the plurality of sampling ports in parallel;
• encode, using an interleaved encoding scheme, the audio signals sampled at the plurality of sampling ports to generate one data stream, the plurality of sampling ports being triggered by a same clock signal to ensure an accuracy of alignments of decoded audio signals based on the data stream in a range of a microsecond order;
• and
• in response to the audio device being connected to the computing terminal, send, in real-time or non real-time communication, the data stream to the computing terminal through a wired or wireless connection;
• and the computing terminal is configured to:
• decode the data stream and reconstruct the audio signals sampled at the plurality of sampling ports, thereby ensuring the accuracy of the alignments of the decoded audio signals in a range of a microsecond order;
• perform one or more multi-input audio processing schemes to obtain one or more enhanced audio signals, each multi-input audio processing scheme corresponding to one of the one or more enhanced audio signals;
• and
• perform an action based on a result of at least one of the one or more enhanced audio signals.
