In the N +1 th time slot, if the second audio end monitors a NAK packet sent by the first audio end, or the second audio end does not monitor an ACK packet sent by the first audio end in the N +1 th time slot, the first acknowledgement result is that the first audio end does not receive the audio data packet in the N th time slot.

3. The method according to claim 1, wherein in the N +2 th time slot, the first audio peer determining whether the second audio peer receives the audio data packet in the nth time slot to obtain a second determination result, comprising:

In the N +2 th time slot, if the first audio end receives a received status packet sent by the second audio end, or the first audio end does not receive a data packet transmission request sent by the second audio end in the N +2 th time slot, the second acknowledgement result is that the second audio end receives the audio data packet in the nth time slot;

in the N +2 th time slot, if the first audio end receives a data packet transmission request sent by the second audio end or does not receive a receiving status packet, the second acknowledgement result is that the second audio end does not receive the audio data packet in the nth time slot.

4. The method of claim 1, wherein the determining, by the first audio end, whether the first audio end and the second audio end are state-synchronized according to the first confirmation result and the second confirmation result comprises:

if the first audio end and the second audio end both receive the audio data packet in the Nth time slot, the first audio end or the second audio end determines that the states of the first audio end and the second audio end are synchronous;

if at least one of the first audio end and the second audio end does not receive the audio data packet in the Nth time slot, the first audio end or the second audio end determines that the state of the first audio end is not synchronous with the state of the second audio end.

5. the method according to claim 1, wherein after the second audio end acknowledges that the first audio end receives the audio data packet at the nth time slot at the N +1 th time slot, the method further comprises:

if the second audio end does not receive the audio data packet in the nth time slot, the second audio end sends the data packet transmission request or the unreceived receiving state packet to the first audio end in the N +2 th time slot;

and in the N +3 time slot, the first audio end sends a requested audio data packet to the second audio end, wherein the requested audio data packet is the audio data packet or a part of audio data packets of a specific sound channel in the audio data packet.

6. the method of claim 5, further comprising:

if the second audio end does not receive the requested audio data packet in the N +3 time slot, the second audio end sends the data packet transmission request or the non-received receiving status packet to the first audio end in the N +4 time slot until the second audio end receives the requested audio data packet sent by the first audio end.

7. The method according to claim 1, wherein after the second audio end confirms that the first audio end does not receive the audio data packet in the nth time slot at the N +1 th time slot, the method further comprises:

In the (N + M) th time slot, the first audio end and the second audio end respectively receive the audio data packet, and M is an integer greater than 1;

at the N + M +1 time slot, the second audio end determines whether the first audio end receives the audio data packet at the N + M time slot, so as to obtain a third determination result;

8. The method of claim 7, wherein determining, by the first audio end or the second audio end according to the third confirmation result and the fourth confirmation result or according to the third confirmation result and the second confirmation result, whether the state of the first audio end and the second audio end is synchronized comprises:

if the first audio end receives the audio data packet at the N + M time slot and the second audio end receives the audio data packet at the N time slot, or if the first audio end and the second audio end both receive the audio data packet at the N + M time slot, the first audio end or the second audio end determines that the states of the first audio end and the second audio end are synchronous;

If the first audio end does not receive the audio data packet in the N + M time slot, or the second audio end does not receive the audio data packet in both the N time slot and the N + M time slot, the first audio end or the second audio end determines that the first audio end and the second audio end are not in state synchronization.

9. A method of transmitting audio data packets, for application to an audio source, the method comprising:

In the Nth time slot, sending audio data packets to the first audio end and the second audio end, wherein N is any integer greater than or equal to zero;

At the N +1 th time slot, confirming whether the first audio end receives the audio data packet at the Nth time slot;

and when the first audio end is determined not to receive the audio data packet in the Nth time slot, sending the audio data packet to the first audio end and the second audio end again in the (N + M) th time slot so as to enable the state between the first audio end and the second audio end to be synchronous, wherein M is an integer greater than 1.

10. the method of claim 9, wherein the step of confirming whether the audio packet is received by the first audio end in the nth time slot in the N +1 th time slot comprises:
