Implemented using libopus for the Opus codec, same as is used in Discord.
This adds the following cvars:
- `voice_chat` On/Off, triggers self-deafen state on server via weaponprefs
- `voice_mode` Activity/PTT
- `voice_selfmute` On/Off, triggers self-mute state on server via weaponprefs
- `voice_inputamp` -30 to 30, scales input by value in decibels
- `voice_activationthreshold` -30 to 0, if any peak in a frame is higher, activates voice
- `voice_loopback` On/Off, plays back local transcoded voice
- `voice_proximity` On/Off, enables proximity effects for server
- `voice_distanceattenuation_distance` distance in fracunits to scale voice volume over
- `voice_distanceattenuation_factor` distance in logarithmic factor to scale voice volume by distance to. e.g. 0.5 for "half as loud" at or above max distance
- `voice_stereopanning_factor` at 1.0, player voices are panned to left or right speaker, scaling to no effect at 0.0
- `voice_concurrentattenuation_factor` the logarithmic factor to attenuate player voices with concurrent speakers
- `voice_concurrentattenuation_min` the minimum concurrent speakers before global concurrent speaker attenuation
- `voice_concurrentattenuation_max` the maximum concurrent speakers for full global concurrent speaker attenuation
- `voice_servermute` whether voice chat is enabled on this server. visible from MS via bitflag
- `voicevolume` local volume of all voice playback
A Voice Options menu is added with a subset of these options, and Server Options has server mute.
All values besides 0 and 1 have been unused for a while. Quite frankly, if the gamestate resend doesn't fix them, a rejoin won't either, so kicking them is just adding extra steps.
- dumpconsistency cvar is always enabled (rather than a define), but is now a cheat.
- It now dumps on resend, instead of on consistency failure kick. (Those don't even happen on too many resyncs anymore, anyways...)
- It now dumps for both the server & the client that is resyncing, so there's gamestates to compare. The two files are given names with metadata so they can be matched up.
It's not great, but it was easy enough to do and more useable than having 0 tools to inspect resync at all.
