Logan CusanoandClaude Opus 5	ceb2836371	Raise tail pad to 3s so short transmissions are not clipped ... The recording window is anchored to OP25 control-channel timestamps, but the buffered audio lags those by roughly 1.5s. Trim logs across seven calls measured the offset at 0.84-1.62s, consistently present. At a 1.0s pad a short call closed its window before the voice arrived: a 0.97s control-channel call closed at T+1.97 while voice started around T+1.5, capturing ~0.4s of speech and cutting mid-word. Confirmed by a 0.57s file whose final 0.10s measured -12.2dB against its own -18.2dB average - clipped speech, not a tail - and by two short calls that logged no trim at all because no trailing silence remained. Being generous is free here: trim_silence already strips trailing silence back to the guard margin before upload, so long calls are unaffected while short ones gain the window they need. Over-capture costs nothing; under-capture loses words permanently. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-04 22:34:17 -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.
