Adaptive audio processing method, device, computer program, and recording medium thereof in wireless communication system

A second device in a wireless communication system, the device comprising:

• a transceiver for performing signal transmission and reception with another device;
• and
• a processor for controlling the transceiver and the second device;
• wherein the processor is configured to:
• decode a first data of audio data for an at least one channel based on a first codec parameter, the audio data for the at least one channel being encoded and transmitted from a first device;
• render the decoded first data for the at least one channel transmitted from the first device;
• receive, via an external control, information signaling presence of a detected error in a specific portion in the audio data for the at least one channel transmitted from the first device, wherein the device does not use the specific portion of the audio data for the at least one channel transmitted from the first device;
• and
• render second data which is substitute audio data of the specific portion of the audio data for the at least one channel transmitted from the first device based on a second codec parameter,
• wherein the second data is generated by the second device based on the audio data for the at least one channel transmitted from the first device.
