Abstract
An audio processing chip includes a detector circuit, a first-in first-out (FIFO) circuit, and an adjustment circuitry. The detector circuit is configured to detect an audio stream to output an enable signal. The FIFO circuit is configured to start outputting audio data corresponding to a channel in the audio stream to be a first signal. The adjustment circuitry is configured to process the first signal, in order to generate an output signal and transmit the output signal to a speaker.

An audio processing chip, comprising:
- a detector circuit configured to detect an audio stream to output an enable signal;
- a first-in first-out (FIFO) circuit configured to start outputting audio data corresponding to a channel in the audio stream to be a first signal;
- and
- an adjustment circuitry configured to process the first signal, in order to generate an output signal and transmit the output signal to a speaker.
A multichannel system, comprising:
- a first audio signal processing chip configured to process first audio data in an audio stream, in order to generate a first output signal;
- and
- a second audio signal processing chip configured to process second audio data in an audio stream, in order to generate a second output signal,
- wherein each of the first audio signal processing chip and the second audio signal processing chip comprises:
- a detector circuit configured to detect the audio stream to output an enable signal;
- a first-in first-out (FIFO) circuit configured to start outputting a corresponding one of the first audio data and the second audio data to be a first signal;
- and
- an adjustment circuitry configured to process the first signal, in order to generate a corresponding one of a first output signal and a second output signal.
An audio signal processing method, comprising:
- detecting an audio stream to output an enable signal;
- starting, by a first-in first-out (FIFO) circuit, outputting audio data in the audio stream to be a first signal;
- and
- processing the first signal to generate an output signal and transmit the output signal to a speaker.
