Abstract:
Disclosed are a low-delay audio distribution method, module and apparatus based on a network card. The method comprises the following steps: S1: acquiring an audio distribution instruction sent by a master control module, and requesting audio data from the master control module; S2: acquiring audio data sent by the master control module, and storing the audio data in a cache memory; S3: acquiring timing information of a timer, and periodically sending the audio data to a target device; and S4: determining whether a cache amount in the cache memory is lower than a preset value, if so, executing S1, and if not, executing S3. In the present invention, by means of the precise timing of a timer, the apparatus can accurately send audio data to a target device in real time, such that a stable playing effect is brought about to system audio distribution.
