Improvements in a method of processing wideband audio signals by a sub-band coding system are provided. Linear codes having frequency components in which audio signal power is concentrated are selected from linear codes separated into a plurality of frequency band components and decoded. The presence or absence of sound in the audio signals is detected by referring to the selected linear codes and/or a gain coefficient is determined. Level control of the decoded linear codes is performed by using the thus determined gain coefficient.
