From the new header file: * MonoView<>: A single channel contiguous buffer of samples. * InterleavedView<>: Channel samples are interleaved (side-by-side) in the buffer. A single channel InterleavedView<> is the same thing as a MonoView<> * DeinterleavedView<>: Each channel's samples are contiguous within the buffer. Channels can be enumerated and accessing the individual channel data is done via MonoView<>. There are also a few utility functions that offer a unified way to check the properties regardless of what view type is in use.
