Audio data transmission method and apparatus

An audio data transmission method, applied to a receiving device, the method comprising:

• receiving processed audio data, and determining a pulse code modulation (PCM) timing of the processed audio data, the PCM timing comprising a clock frequency of a first clock signal, a clock frequency of a second clock signal and a duration of a high level in each cycle of the first clock signal;
• determining a frequency of sampling according to the clock frequency of the first clock signal;
• determining a number of slots according to the clock frequency of the second clock signal and the duration of the high level in each cycle of the first clock signal;
• and
• obtaining audio data having a preset bit width occupied by audio data for each slot from the processed audio data according to the number of slots and the preset bit width.

An audio data transmission apparatus, applied to a sending device, the apparatus comprising:

• a processor;
• and
• a memory configured to store instructions executable by the processor,
• wherein the processor is configured to:
• parse input audio data to be processed, and obtain, for the input audio data to be processed, a frequency of sampling, a number of slots and an original bit width of audio data of each slot;
• determine the frequency of sampling as a clock frequency of a first clock signal;
• determine a clock frequency of a second clock signal according to the clock frequency of the first clock signal, the number of slots and a preset bit width occupied by audio data;
• determine a duration of a high level in each cycle of the first clock signal according to the clock frequency of the second clock signal and the number of slots;
• and
• output processed audio data according to a pulse code modulation (PCM) timing determined by the clock frequency of the first clock signal, the clock frequency of the second clock signal and the duration of the high level in each cycle of the first clock signal.
