AB  - Techniques where a stereo or a multichannel signal is decomposed into spatial source-labeled time-frequency slots by level, time-difference, and coherence metrics have become popular in recent years. Good examples are binaural cue coding and up/downmixing techniques. In the article, we will provide an overview and discuss parallel approaches in the field of array processing and blind source separation. Typically, time-frequency slots are formed from subband representations of signals. However, it is also possible to produce a similar spatial decomposition for a parametric representation (sinusoids, transients, and noise) of a stereo or multichannel audio signal. Advantages and disadvantages of the two approaches for audio coding applications are discussed in this article.
