## Detailed Description

Represents a set of audio channel types.

For example, you might have a set of left + right channels, which is a stereo channel set. It is a collection of values from the AudioChannelSet::ChannelType enum, where each type may only occur once within the set.

The documentation below lists which AudioChannelSet corresponds to which native layouts used by AAX, VST2/VST3 and CoreAudio/AU. The layout tags in CoreAudio are particularly confusing. For example, the layout which is labeled as "7.1 SDDS" in Logic Pro, corresponds to CoreAudio/AU's kAudioChannelLayoutTag_DTS_7_0 tag, whereas AAX's DTS 7.1 Layout corresponds to CoreAudio/AU's kAudioChannelLayoutTag_MPEG_7_1_A format, etc. Please do not use the CoreAudio tag as an indication to the actual layout of the speakers.
