Claim:
1. A method comprising: providing a left audio channel signal and a right audio channel to an encoder, wherein the encoder is configured to determine a first encoded audio channel signal and a second encoded audio channel signal; combining, using a first audio codec of the encoder, at least one sub band component of the left audio channel signal with a respective sub band component of the right audio channel signal in order to determine a respective at least one sub band component of the first encoded audio channel signal and a respective at least one sub band component of the second encoded audio channel signal; providing, an audio codec indicator for the at least one sub band, wherein the audio codec indicator is indicative that the first audio codec is used for encoding the at least one sub band; selecting the first audio codec of the encoder; and bypassing the combining with the first audio codec, such that the first encoded audio channel signal is the left audio channel signal and the second encoded audio channel signal is the right audio channel signal, wherein the audio codec indicator provided for the at least one sub band indicates that the at least one sub band of the first and second encoded audio channel signal is determined based on combining a respective sub band component of the left audio channel signal with a respective sub band component of the right audio channel signal.
