Audio processing circuit supporting multi-channel audio input function

A circuit comprising:

• a plurality of analog-to-digital converters (ADCs), configured to operably convert analog audio signals of a plurality of channels into corresponding digital audio data, the plurality of ADCs including a target ADC utilized for processing an analog audio signal of a target channel in the plurality of channels;
• and
• a control chip, coupled with the plurality of ADCs, and configured to operably control an audio data output order of the plurality of ADCs, to operably instruct the target ADC to output an audio data of the target channel during a target period, and to operably instruct remaining ADCs of the plurality of ADCs not to output audio data in the target period;
• wherein the control chip is further configured to operably define a data timing of the target channel according to a data receiving time point of the audio data of the target channel, and then to operably define a data timing of remaining channels of the plurality of channels according to the data timing of the target channel;
• after the control chip defines the data timing of the plurality of channels, the plurality of ADCs process the analog audio signals of the plurality of channels and output the audio data of the plurality of channels in turns according to an assigned order configured by the control chip to form a serial data signal, and the control chip separates the digital audio data of different channels from the serial data signal according to the data timing of the plurality of channels.
