1. An audio transmission method implemented by a first device, the audio transmission method comprising:
receiving noise energy data and transmission efficiency data from a second device, wherein the noise energy data indicate noise energy or noise loudness, and wherein the transmission efficiency data indicate quality of a wireless channel between the first device and the second device;
determining a first bit rate based on the noise energy data;
determining a second bit rate based on the transmission efficiency data;
encoding an audio stream based on a lower bit rate of the first bit rate and the second bit rate to obtain audio data; and
sending the audio data to the second device.
