Examples of audio type lattices

We identified the following properties of PCM audio and some example enumerations:

The following diagrams display only some of these properties. Any lattice beyond the "Moderately complex" becomes tedious to generate without additional tools.

For each lattice, you may also imagine a mirror lattice representing a separate endianness. This lattice would have a node which is a 'sibling' to each node in above lattices. Three-dimensionally you may consider this to be another axis of movement, and the lattice would lay above an existing lattice (essentially doubling the number of types).

Also, in each lattice, only transforms which affect a single attribute at a time are considered. It is entirely feasible to imagine a transform function which compresses a transform->type->transform into a single transform between two types.
