An audio forwarding method, an audio forwarding method device and a storage medium are described. The audio forwarding method comprises: establishing a first communication link with a sound source device based on a first wireless communication protocol; establishing a second communication link with an audio playback device based on a second wireless communication protocol; receiving first audio data from the sound source device through the first communication link; processing the first audio data to generate second audio data, and storing the second audio data into a second buffer; and transmitting the second audio data to the audio playback device through the second communication link. The second audio data in the second buffer is acquired according to a predetermined encoding frame length, a current frame is processed as an empty data frame if the second audio data in the second buffer is not successfully acquired, and an audio data packet containing the empty data frame is transmitted or not transmitted to the audio playback device through the second communication link within a current transmission time.
