The number of apparent playback channels can differ from the number of physical channels of the recording medium, i.e., 2-track monophonic recordings. In this example, the soundChan element should record the fact that there is a single output channel, while the trackConfig element should capture the existence of two physical tracks. This element is analogous to MARC field 344 subfield g.
