feat(take95): the album exports, and the split was 11 seconds out
Master: 61.0 min, 2 ch, 48 kHz, 24-bit. I = -14.0 LUFS on the nose, peak
-0.9 dBFS under a -1.0 ceiling, LRA 12.7 LU. L-R difference RMS is -22.4 dB, so
it is genuinely stereo and not dual-mono — worth measuring rather than assuming,
given the first attempt collapsed to one channel.
THE BUG THAT WOULD HAVE SHIPPED. take-master trims leading silence before
loudnorm sees it, so the master starts 10.94 s later in the music than the raw
take does. The segments were computed against the RAW take. Splitting with
unshifted offsets puts every boundary eleven seconds late — each track beginning
eleven seconds into the previous one's tail. The output would have played
perfectly and been wrong throughout.
Two guards in take-segments:
--shift subtract the measured head trim. Clamped at 0, because the first
track legitimately goes negative: PLN focuses a .tidal a few seconds
BEFORE he evaluates it (log says 7.4 s, first sound is at 10.94 s).
--master probe the mastered file and clamp to its duration. The master is
trimmed at the TAIL too (1.45 s), so without this the last segment
ran past EOF and ffmpeg would have written a short final track in
silence.
Now: contiguous, starts at 0, sums to 3661.2 s — exactly the master's length.
AND A SHADOWING BUG FOUND WHILE FIXING IT. The per-segment loop bound `start`
and `end`, the same names as the take window, so the summary line printed the
LAST SEGMENT as if it were the whole take: "1970-01-01 01:55 — 5.1 min". The
segments were correct the whole time; only the report lied. That is the kind of
defect that ships, because the payload looks right and nobody re-reads a header.
GENERATIVE METADATA, per PLN's ask, derived not typed:
title backlog.md via setlist.py (the SSOT reaches the ID3 tag)
TBPM backlog BPM, NOT setcps — reference_tempo_from_audio, setcps is not
felt tempo. gimme_acid is setcps 80 played as 160 half-time DnB, and
you_my_sunshine is setcps 144 against a felt 166. Tagging 80 would
have been a measured number that misleads.
grouping the set section (Ouverture / SUNSET / NuJazz / NUIT)
comment orbit inventory from the .tidal via pvlint's parser, plus the source
path, so any track can be traced back to the code that made it
Metadata says REHEARSAL, not gig: album "OPAL 2026 — rehearsal, J-6", date
2026-08-02, no venue, no lineup, no poster (feedback_metadata_vs_mastering — gig
metadata is canonical only in Web/www/next/content/lives/).
lime_tacos is track 7 at 1:49. He played it, then cut it from the set an hour
later. The take records what happened, so it stays, tagged "not in the final
set".
Committed: segments.json, track_metadata.json, analysis.json — the provenance.
