1. A method of processing an audio signal, the method comprising:
receiving a CPE (Channel Pair Element) encoded via MPEG Surround 212 (MPS212) and information indicating whether the CPE uses an internal channel (IC) processing;
generating a band-limited IC signal based on the CPE and an internal channel gain (ICG) in case that the information indicates that the CPE uses the IC processing;
downmixing a pair of SBR (Spectral Band Replication) parameters into a mono SBR parameter based on a rendering parameter of a format converter;
generating a full band IC signal based on the generated band-limited IC signal and the mono SBR parameter; and
generating stereo output signals, based on the generated full band IC signal.
