You'll have to fix the rc2-core merge conflicts, and I would like to see some better commenting of the changes/additions to explain their functionality. But I definitely would love to get this added in, thanks for the work! |
Implement audio-level based VOX radio control with RX/TX gate detection, startup/reconnect suppression, learned noise-floor calibration, and gated RX forwarding. Wire VOX mode into daemon startup, local audio callbacks, and example configuration.
Route WebRTC TX audio through the VOX radio before sending it to the local TX device. Track explicit VOX transmit requests so alert tones can key and play correctly while preventing audio from other selected radios from opening the VOX radio.

I rebased the VOX branch onto current I also added more section-level comments around the VOX changes, especially the audio callback wiring, raw RX monitoring path, startup/warmup calibration, RX/TX gate behavior, hang timer behavior, and encoded RX forwarding. Validation:

Summary
This PR implements the daemon VOX control mode and makes it usable for audio-only radio setups such as an FT-991A running DATA VOX through a USB audio interface.
VOX can now drive radio RX/TX state from audio levels, forward receive audio only when active, and pass transmit audio to the configured TX audio device only when that specific radio has been keyed.
What Changed
VoxRadioimplementation forcontrolMode: 0rc2-coresubmodule for reliable initial WebRTC audio negotiationWhy
This enables radios that can self-key from audio, such as an FT-991A in DATA VOX mode, to work without CAT/PTT control.
