Abstract

The embodiment of the application discloses an audio data sending method, electronic equipment and a storage medium. Based on the audio data sending method in the embodiment of the application, the application audio data obtained by processing the received initial audio data by each virtual sound card is stored in the corresponding buffer space, and the access address of the buffer space is sent to the target application, so that the target application accesses the application audio data required by the target application according to the access address. The finally available application audio data only needs to be stored once after the virtual sound card is generated, only access address information needs to be transmitted between a target application needing to use the application audio data and the virtual sound card, and the target application can acquire the needed data from the cache space according to the access address information, so that the data transmission amount among different data processing nodes is reduced, and the data transmission and storage efficiency is improved.
