Abstract (en)
An apparatus comprising means configured to: obtain two or more separate audio signal inputs; determine signal activity within the two or more separate audio signal inputs; determine a coding mode from three or more coding modes, wherein at least one of the three or more coding modes comprises at least one adaptive discontinuous transmission coding mode and the coding mode is determined based on the signal activity within the two or more separate audio signal inputs; and encode the two or more audio signal inputs based on the determined coding mode.
