The embodiment of the invention provides an audio processing method, device and system, a storage medium and equipment, and the method comprises the steps: determining a channel meeting a forwarding condition from audio data transmitted by a plurality of channels; updating the audio transmission identifier of each channel according to the channel meeting the forwarding condition; wherein the audiotransmission identifier comprises a forwarding state identifier and a non-forwarding state identifier; and determining a channel with the audio transmission identifier being a forwarding state identifier, and obtaining an FEC packet transmitted by the channel. According to the embodiment of the invention, the problem that the forwarded audio is interrupted or interrupted is solved, and the user experience is improved. The FEC packet is transmitted only when the channel with the audio transmission state being the forwarding state identifier transmits the audio data packet loss, so that uselessFEC packet transmission and useless FEC coding can be reduced, and the calculation overhead and bandwidth overhead of a server and a client are saved.
