Audio data transmission method and device, equipment and medium

The invention discloses an audio data transmission method and device, equipment and a medium, and relates to the technical field of coding and decoding. The audio data transmission method is executed by a first terminal, and comprises the following steps: forming second audio data based on one or more pieces of high-order data of first audio data; and sending the first audio coding packet corresponding to the second audio data. The second audio data is formed based on one or more high-order data of the first audio data, so that the amount of data to be transmitted can be reduced, and the possibility that the first audio coding packet is successfully transmitted at a time is improved. 本申请公开了一种音频数据传输方法、装置、设备及介质，涉及编解码技术领域。所述音频数据传输方法由第一终端执行，包括：基于第一音频数据的一个或多个高位数据，形成第二音频数据；发送第二音频数据对应的第一音频编码包。本申请基于第一音频数据的一个或多个高位数据来形成第二音频数据，能够减少待传输的数据量，从而提高第一音频编码包一次性传输成功的可能性。
