Detailed Description

A channel layout is a 64-bits integer with a bit set for every channel.

The number of bits set must be equal to the number of channels. The value 0 means that the channel layout is not known.

Note: this data structure is not powerful enough to handle channels combinations that have the same channel multiple times, such as dual-mono.
