Logan CusanoandClaude Opus 5	d6dfe5a293	Drive call boundaries from audio, use the console only for the label ... The control channel was wrong in both directions. Grants fire 0.84-1.62s before anyone speaks, and srcaddr can drop to 0 while someone is still talking - one recording came back "-1.61s lead, -0.00s tail", the trim finding nothing to remove because the window had closed on live speech. Confirmed by ear: the cut lands at a word boundary on an unfinished word. Audio is ground truth for WHEN. The console remains the only source of WHO, so it still supplies talkgroup, alias and rid. START voice onset in the captured audio, with a 0.25s pre-roll that now covers only chunk quantisation and threshold ramp-up rather than a variable control-channel offset. STOP call_silence_timeout seconds of silence heard in the audio. LABEL resolved AT CLOSE from a bounded rolling history of console observations overlapping the window, +4s/-2s, because there is no guaranteed ordering between a grant and its audio. SPLIT a console talkgroup change still forces a cut, since two calls with no silence between them would otherwise merge into one. Capture now emits raw PCM instead of MP3. Silence detection becomes integer arithmetic per chunk with no decode, trimming becomes a byte offset slice rather than a second ffmpeg pass, and MP3 encoding happens exactly once at save - uploads are no longer double-encoded. Audio with no talkgroup anywhere in its window is discarded rather than uploaded: an untagged call silently poisons incident correlation, which is worse than losing the audio. Logged at ERROR and counted on /api/status. When capture produces no audio at all the old console state machine still runs, so a node with a broken audio path keeps reporting radio activity. That is now the only consumer of call_idle_timeout. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-06 18:19:45 -04:00
Logan CusanoandClaude Opus 5	7c4a3f2f20	Make PulseAudio readiness mean a live connection, clear stale socket state ... The pulse_socket named volume survives container recreation, so after a compose recreate the previous container's /run/pulse/pid and native socket were still present. PulseAudio read the stale pid file, decided a daemon was already running, and refused to start: E: [pulseaudio] pid.c: Daemon already running. The entrypoint still reported "PulseAudio socket ready" because it only checked that the socket file existed - and a stale one did. Capture then failed in a restart loop against a dead daemon. Readiness in both the op25 entrypoint and drb-edge-node now means a pactl probe actually succeeds. Stale pid/socket are removed only when that probe fails, so a live daemon's socket is never deleted. pulseaudio-utils was missing from the edge-node image (only libpulse0 was installed), so no pactl binary existed there at all - added. Capture exits are now classified: a missing source logs at ERROR and names the configured PULSE_SOURCE, rather than looking identical to "daemon not up yet". Retrying forever against a wrong source name is how the April PulseAudio failure stayed hidden. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-04 22:10:28 -04:00
Logan CusanoandClaude Opus 5	b0a8ed2a5a	Fix tail truncation, decouple call length from buffer, trim silence ... Measured six recordings off a live P25 node and found two independent defects causing lost audio at the end of calls: - stop_recording() sliced the ring buffer immediately, so if the MP3 muxer had not yet delivered the tail the file was silently short. Now waits (bounded, 2s) until buffered audio covers the end epoch. - TGID-change closes used the new grant's epoch as the end with no pad at all, guaranteeing truncation on every split. Tail pad is now a setting, default raised 0.5s -> 1.0s. The ring buffer also capped maximum call length: a call longer than the buffer had its front silently clamped. The ring now serves the pre-roll only, with a per-call accumulator for the rest, bounded at 4.8MB. Clamping is loudly warned rather than silent. Uploads averaged 63% silence, which inflates STT cost and is a known Whisper hallucination trigger. Leading/trailing silence is now trimmed conservatively (-40dB, 0.25s guard, internal pauses untouched). started_at/ended_at still describe the call; new audio_* fields carry the trimmed audio bounds so playback can map back to wall clock. All-silence recordings are skipped and logged instead of uploaded. Also: log measured control-channel idle on idle-timeout closes so CALL_IDLE_TIMEOUT can be tuned from data, and quiet the httpx logger which emitted ~170k lines/day of poll noise.
