1. An audio processing method, applied to a wireless earphone, the method comprising:
receiving a to-be-presented audio signal sent by a playback device in a wireless transmission mode, wherein the to-be-presented audio signal comprises at least one of a first audio signal and a second audio signal, the first audio signal is an audio signal that has undergone rendering processing performed by the playback device, and the second audio signal is an audio signal that is to be rendered;
performing the rendering processing on the second audio signal, to obtain a third audio signal, if the to-be-presented audio signal comprises the second audio signal; and
performing subsequent audio playing, according to at least one of the first audio signal and the third audio signal;
wherein before the receiving the to-be-presented audio signal sent by the playback device in the wireless transmission mode, the method comprises:
sending an indication signal to the playback device in the wireless transmission mode, wherein the indication signal is used to instruct the playback device to perform rendering on an original audio signal according to a corresponding preset processing mode, to obtain the to-be-presented audio signal;
wherein the indication signal comprises an identification code;
wherein if the identification code is a first field, the playback device does not perform rendering on the original audio signal, the to-be-presented audio signal comprises the second audio signal but not the first audio signal, and the wireless earphone performs full rendering on the original audio signal;
if the identification code is a second field, the playback device performs the full rendering on the original audio signal, the to-be-presented audio signal comprises the first audio signal but not the second audio signal, and the wireless earphone performs no rendering on the original audio signal; and
if the identification code is a third field, the playback device performs rendering on a part of the original audio signal, the to-be-presented audio signal comprises the first audio signal and the second audio signal, and the wireless earphone performs rendering on a remaining part of the original audio signal.
