[Feature Request] OBS Audio Mixer Volume

[dennisrijsdijk]

Describe the solution you'd like
Add an effect to change OBS Audio Mixer Volume through Firebot's OBS Websocket

Additional context
Ideally, this would both include a guided mode (using an rz-slider from -100db (silent) to 0db (loud) and a variables input, which should be validity checked on runtime.

I am willing to work on this feature

OBS accepts an audio volume value between +26.0 dB and -96.0 dB using the advanced audio settings UI. Any value less than -96.0 is wholly treated as negative infinity and will absolutely be silent, while -96.0 can still be technically audible under certain circumstances (think audio effects, or VST plugins, which are performed after the input volume adjustment stage). It is also possible to manually edit OBS's scene collection file and get values larger than +26 dB, but it seems to be hard capped at or around +92.0 dB.

A range from -96.1 dB (hard muted) to +26.0 dB would mimic the OBS advanced audio settings UI, and a range from -96.1 dB (hard muted) to 0.0 dB would mimic the OBS main mixer UI.
