Intensity Stereo Coding (ISC) is a joint-channel audio coding tool that is part of the ISO/MPEG standards. ISC can introduce severe distortions if applied to full bandwidth or to audio signals with a dynamic or wide spatial image. In contrast, Binaural Cue Coding (BCC) is a systematic approach for representing auditory spatial cues which includes ISC as a subset. BCC is independent of the time/frequency resolution used by the coder, thus it can be optimized for spatial image reproduction. Subjective listening tests confirm that ISC is significantly compromised by an inappropriate time/frequency resolution and that BCC has superior quality and robustness.
