This is probably one of the most requested features for obs-websocket.
This currently works by firing an event to all explicit subscribers
with an array of all active audio sources every **60 milliseconds.**
The `inputLevelsMul` field follows this data format:
Base: [Channel, Channel]
Channel: [magnitude (mul), peak (mul), input_peak (mul)]
*Not Muted* *Muted*
Example: [[0.3, 0.5, 0.9], [0.0, 0.0, 0.0]]
(input_peak is the actual peak value, before volume adjustment.)
You may notice that the values are only in mul. This is because we are
trying to cut down on bandwidth. dB values can be calculated using this
formula:
`dB = 20.0 * log10(mul)`
- Implements a WIP ObsWebSocketApi, for obs-websocket-api.h. Events are
finished, but requests are not.
- Some logging improvements
- A bit of code cleanup around the plugin
