Embodiment 1
[0051] A method for controlling an audio processor, comprising the following steps:
[0052] One, the audio data is received by the audio processing module 2 after being imported from the audio input module 1, and the audio storage unit 21 in the audio processing module 2 stores the audio data after the audio processing unit 22 converts the digital audio data into analog audio data;
[0053] Two, the audio processing unit 22 transmits the analog audio data to the audio selection module 3, the audio controller 31 transmits the audio data to the operating mode control unit 32, and the operating mode control unit 32 works to transmit the audio data to the audio path module 4;
[0054] 3. After the audio power amplifier 42 in the audio path module 4 amplifies the audio signal, the analog switch 41 is controlled to transmit the amplified audio signal to the audio output module 5;
[0055] 4. The sound source processor 51 in the audio output module 5 selectively transmits audio data...
Embodiment 2
[0057] A method for controlling an audio processor, comprising the following steps:
[0058] One, the audio data is received by the audio processing module 2 after being input from the audio input module 1, and the audio storage unit 21 in the audio processing module 2 stores the audio data after the audio processing unit 22 converts the digital audio data into analog audio data;
[0059] Two, the audio processing unit 22 transmits the analog audio data to the audio selection module 3, and the audio controller 31 transmits the audio data to the standby mode control unit 33. After selecting a suitable standby time, the audio controller 31 closes the standby mode control unit 33 , the standby mode is released, and the standby mode control unit 33 works to transmit the audio data to the audio path module 4;
[0060] 3. After the audio power amplifier 42 in the audio path module 4 amplifies the audio signal, the analog switch 41 is controlled to transmit the amplified audio signal...

Abstract
The invention discloses an audio processor and a control method thereof. The audio processor comprises an audio input module, an audio processing module, an audio selection module, an audio path module and an audio output module. The audio processing module comprises an audio storage unit and an audio processing unit, the audio selection module comprises an audio controller, and the audio controller is connected with a working mode control unit and a standby mode control unit. The audio access module comprises an analog switch and an audio power amplifier, and the audio output module comprisesa sound source processor. According to the invention, the work mode control unit or the standby mode control unit is controlled to work through the information transmission quantity, and the standbymode control unit can avoid the phenomena that the audience cannot completely receive the audio data and the audio data is lost due to the congestion of the data signals during the work; meanwhile, the converter designed by the invention converts the digital audio data stored in the audio storage unit into the analog audio data, so that the phenomenon of sound interruption at the initial positionof the audio to be played can be avoided.
Description
technical field [0001] The invention relates to the field of audio processors, in particular to an audio processor and a control method thereof. Background technique [0002] An audio processor, also known as a digital processor, processes digital signals, and its internal structure is generally composed of an input part and an output part. Its internal functions are more complete, and some have processing modules that can be dragged and programmed, which can be composed of systems freely built by users. [0003] The ways in which audio processor control software is implemented in the prior art are developed based on different operating systems, resulting in cumbersome software development and high operating costs. At the same time, the ordinary digital audio data in the existing audio processor is prone to sound interruption at the beginning of the audio to be played during transmission, which may cause intermittent audio signals during audio transmission. [0004] At the...
