/*

|
* Naming:
|
|
*
|
|
* A track is a single input/output stream (e.g. line-in,
|
|
* microphone, etc.). Channels are then single streams
|
|
* within a track. A mono stream has one channel, a stereo
|
|
* stream has two, etc.
|
|
*
|
|
* Input tracks can have 'recording' enabled, which means
|
|
* that any input will be hearable into the speakers that
|
|
* are attached to the output. Mute is obvious. A track
|
|
* flagged as master is the master volume track on this
|
|
* mixer, which means that setting this track will change
|
|
* the hearable volume on any output.
