# build-voice-pack.sh — turn a SOURCE recording plus a CROP OFFSET into a
|
||||
# deployable frank-tts voice pack: the reference WAV, the engine's own speaker
|
||||
# artifacts made from it, and manifest.json provenance.
|
||||
#
|
||||
# THE PACK. $PACKS_DIR/<voice>/ carries the three members the pack law in
|
||||
# scripts/frank-tts.env names:
|
||||
#
|
||||
# reference.wav the crop: 24 kHz mono PCM (pcm_s16le), 18-25 s of clean
|
||||
# single-speaker audio. This is what makes a voice NAME real
|
||||
# (dankclaw/voiceservice/app.py lists and resolves exactly
|
||||
# this file), so it is written LAST, once everything else in
|
||||
# the pack has been verified.
|
||||
# reference.spk the engine's x-vector: enc_dim 2048 f32 = 8,192 B.
|
||||
# reference.rvq the engine's RVQ code stream: 16 codebooks x 11 bits = 22 B
|
||||
# per 12.5 Hz frame = 22 * floor(samples / 1920).
|
||||
# manifest.json provenance: source path and sha256, crop start/end, sample
|
||||
# rate, duration, the tool + engine commit that made the
|
||||
# artifacts, and the voice name.
|
||||
#
|
||||
# Both artifacts come from the pinned engine build's speaker extractor — the
|
||||
# `qwen-codec` tool of qwentts.cpp at VOICE_PACK_ENGINE_COMMIT — run on the pack's
|
||||
# own WAV, and the extractor names them by swapping the input's extension, so
|
||||
# they land beside reference.wav with nothing to rename. Required, never a
|
||||
# replacement for the WAV: a voice another runtime cannot reuse is not saved.
|
||||
#
|
||||
# THE 10-SECOND GATE — THE REASON THIS SCRIPT EXISTS. Project-wide source-material
|
||||
# invariant: the first 10 s of any sample file used to generate voices is
|
||||
# forbidden material. An offset that starts inside that region is refused with a
|
||||
# nonzero exit BEFORE anything is created — no pack dir, no WAV, no artifact — and
|
||||
# the same gate is asserted a second time from the manifest that was just written
|
||||
# (plus the recorded sha256 against the source it claims). A pack carrying a
|
||||
# forbidden crop therefore cannot survive a build.
|
||||
#
|
||||
# THE ARTIFACT SIZES ARE CHECKED, NOT ASSUMED. They are a property of the codec
|
||||
# config inside the GGUF, so an engine bump that changes enc_dim or the codebook
|
||||
# count fails the build instead of shipping a pack the engine will reject at
|
||||
# synthesis time. Note the interaction with the WAV window: an 18.0 s crop is a
|
||||
# legal reference.wav but only 22 * 225 = 4,950 B of .rvq, under the recorded
|
||||
# 5,456 B floor, so the effective crop window is 19.84-25 s. That is a real
|
||||
# constraint and the builder says so up front rather than failing after a build;
|
||||
# serverAppConfigs-docs/Dankclaw/Voice Packs.md covers what to do on an engine bump.
|
||||
#
|
||||
# WHERE IT RUNS: the host that holds the engine build (Dankclaw). The extractor is
|
||||
# a CPU ggml binary — no GPU, no container, no fleet endpoint, no network. ffmpeg
|
||||
# does the crop; every spawned process runs `nice -n 19` so a pack build never
|
||||
# competes with the text endpoints on that box.
|
||||
#
|
||||
# IT NEVER DELETES. An existing pack is refused unless --force, and --force moves
|
||||
# the whole old directory aside into $PACKS_DIR/.AGENTTRASH/<voice>-<UTC>/ rather
|
||||
# than overwriting or unlinking a single byte.

# --offset SEC crop start, in seconds into the source (must be >= 10)

# engine facts that turn a crop into a pack. Read by
|

# `scripts/build-voice-pack.sh`, which is the only thing that consumes this
|

# file — the running service reads none of it, because the packs themselves are
|

# the interface (see scripts/frank-tts.env for what the shim resolves).
|
||||
#
|
||||
# WHAT IS TRACKED HERE AND WHAT IS NOT. Paths and numbers, never credentials,
|
||||
# which is the same rule the other `scripts/*.env` files follow. The pack
|
||||
# DIRECTORIES are host state under $VOICE_PACK_DIR and stay out of the repo; the
|
||||
# crops that produce them are exactly the kind of decision worth a diff, so the
|
||||
# offsets live here. If a crop changes, change it here and rebuild with
|
||||
# --force — the manifest inside the pack records what was actually cut.
|
||||
#
|
||||
# THE OFFSETS ARE NOT ARBITRARY. Two rules pick them:
|
||||
# 1. The source-material invariant: seconds 0-10 of any sample file are
|
||||
# forbidden voice material. The builder refuses a crop that starts inside
|
||||
# that region and asserts the same thing again from the manifest it just
|
||||
# wrote, so the values below are checked, not trusted.
|
||||
# 2. Speech density: the trial cut these from a silencedetect scan of the
|
||||
# source (noise -35 dB, 0.6 s) and took the longest run of continuous
|
||||
# speech at or past the scan window — a reference that starts mid-word or
|
||||
# contains a page-turn of silence clones the artefacts, not the voice.
|
||||
# serverAppConfigs-docs/Dankclaw/Voice Packs.md carries the recipe.
|
||||
#
|
||||
# WHY THE SHA256 LINES EXIST. A crop offset is a statement about one exact
|
||||
# file: 98.739 s into a re-encode of the same audiobook is a different sentence
|
||||
# and therefore a different voice. The builder hashes the source, compares it
|
||||
# with the pinned digest when one is set, and writes the digest into the pack's
|
||||
# manifest — so a pack can always be traced back to the bytes it was cut from.
|
||||
# The three values below are the trial's digests (2026-10-18), verified against
|
||||
# the files on disk.
|
||||
#
|
||||
# THE ENGINE BLOCK IS A PIN, NOT A DEFAULT. The speaker artifacts come from
|
||||
# `qwen-codec` in the qwentts.cpp tree at $VOICE_PACK_ENGINE_COMMIT: it takes a
|
||||
# 24 kHz WAV, writes the RVQ code stream next to it with the extension swapped,
|
||||
# and with --talker also runs that talker's speaker encoder to write the
|
||||
# x-vector .spk. The talker has to be a **Base** build — the customvoice and
|
||||
# voicedesign GGUFs carry no speaker encoder and the extractor says so. The
|
||||
# sizes the builder then verifies (8,192 B of .spk, 5,456-6,864 B of .rvq) are
|
||||
# derived from the codec config in the GGUF, so an engine bump that changes them
|
||||
# fails the build on purpose; see [[Voice Packs]] for the bump procedure.

# Voice Packs
|
||||
|
||||
A **voice pack** is the unit of identity for **frank-tts**: one directory under
|
||||
`/home/dank/voices`, named by the voice, carrying the reference audio that makes
|
||||
the name real plus the pinned engine's own speaker artifacts and a provenance
|
||||
record. `voice=narrator1` on `POST /v1/audio/speech` resolves to
|
||||
`/home/dank/voices/narrator1/reference.wav` and to nothing else — a name without
|
||||
that file is a 400 that lists the names that do exist, because a silent fallback
|
||||
voice is how a wrong-voice endpoint stays wrong for weeks.
|
||||
|
||||
**Host:** Dankclaw (192.168.0.143) — **Pack root:** `/home/dank/voices`, host
|
||||
state that stays out of the repo, mounted read-only at `/voices` by the façade
|
||||
unit — **Builder:** `scripts/build-voice-pack.sh` with tunables in
|
||||
`scripts/voice-packs.env` — **Seam:** `tests/voice_pack_unit.bats` — **Engine:**
|
||||
arm A `qwentts.cpp`, decided in [[Local TTS and Voice Cloning]].
|
||||
|
||||
Packs are **world-readable on purpose** (`drwxr-xr-x`, owner `dank`): the façade
|
||||
container runs as uid 10000 and reads the mount from outside its own uid map.
|
||||
|
||||
## The required files
|
||||
|
||||
| File | What it is | Who reads it |
|
||||
|------|------------|--------------|
|
||||
| `reference.wav` | the crop: 24 kHz mono `pcm_s16le`, **18–25 s** of clean single-speaker audio | the façade (it is the existence gate for the name) and the engine's boot warmer, which base64s it and registers the voice with no transcript |
|
||||
| `reference.spk` | the engine's x-vector: **8,192 B** = `enc_dim` 2048 × f32 | the engine, for the ICL/`--ref-spk` path |
|
||||
| `reference.rvq` | the engine's RVQ code stream: **5,456–6,864 B**, 16 codebooks × T frames packed at 11 bits = 22 B per 12.5 Hz frame | the engine, for the ICL/`--ref-rvq` path |
|
||||
| `manifest.json` | provenance: source path and sha256, crop start/end offsets, sample rate, duration, the tool and engine commit that made the artifacts, and the `voice` name | humans, and the builder itself on its second gate assertion |
|
||||
|
||||
`qwen-codec.log` rides along with the extractor's own record of the run; the
|
||||
façade ignores anything it does not name and never deletes anything.
|
||||
|
||||
Division of enforcement, which is deliberate and not a gap: the **façade** gates
|
||||
on `reference.wav` because that is the only engine-agnostic term (see the
|
||||
voice-pack law in `scripts/frank-tts.env`); the **builder** is what refuses to
|
||||
emit a pack without its engine artifacts; the **engine** registers a voice from
|
||||
the WAV alone because its own `POST /v1/audio/voices` refuses a lone embedding —
|
||||
it wants `wav_b64` or **both** `spk_b64` and `rvq_b64`. So the artifacts are in
|
||||
the pack to make ICL a per-voice opt-in, not to boot it.
|
||||
|
||||
## How a pack is built
|
||||
|
||||
```bash
|
||||
# everything except the extractor: gate, crop, probe, plan, the manifest it would write
|
||||
scripts/build-voice-pack.sh --dry-run narrator1 /home/dank/voices
|
||||
|
||||
# the real thing, on the host that holds the engine build
|
||||
scripts/build-voice-pack.sh narrator1 /home/dank/voices
|
||||
```
|
||||
|
||||
Crops come from `scripts/voice-packs.env` — per voice: source path, offset,
|
||||
duration, and the source's pinned sha256 — and any of them can be overridden on
|
||||
the command line (`--source`, `--offset`, `--duration`, `--sha256`, `--tool`).
|
||||
`--all` walks `VOICE_PACKS`. The builder assumes no GPU, no container, no fleet
|
||||
endpoint and no network: `ffmpeg` cuts the crop, the pinned extractor makes the
|
||||
artifacts, and both run `nice -n 19` so a build never competes with the text
|
||||
endpoints on that box.
|
||||
|
||||
The extractor is `qwen-codec` in the `qwentts.cpp` tree at
|
||||
`VOICE_PACK_ENGINE_COMMIT` (`5916bf7c79dbb4e66fc059cdc507a79a23a28bb4`). Its
|
||||
usage text, read out of that tree and not guessed:
|
||||
|
||||
```
|
||||
Usage: qwen-codec --model <gguf> [-i <input>] [--talker <gguf>] [--format <fmt>]
|
||||
|
||||
Required:
|
||||
--model <gguf> Codec GGUF (qwen-tokenizer-12hz-*.gguf)
|
||||
|
||||
Optional:
|
||||
--device <name> Compute device: CUDA0, Vulkan0, MTL0, CPU...
|
||||
(default: best available)
|
||||
-i <path> Input. WAV -> encode, .rvq -> decode
|
||||
--talker <gguf> Talker GGUF (Base only). Encode also extracts the speaker
|
||||
embedding and writes it next to the .rvq as a .spk file
|
||||
--format <fmt> WAV output format: wav16, wav24, wav32 (default: wav16)
|
||||
|
||||
Output is auto-named next to input : clip.wav -> clip.rvq, clip.rvq -> clip.wav.
|
||||
```
|
||||
|
||||
Three consequences shape the builder. **There is no `-o`**, so the pack's WAV is
|
||||
staged under its final stem and the artifacts land beside it with nothing to
|
||||
rename. **`--talker` must be a _Base_ talker** — the customvoice and voicedesign
|
||||
GGUFs carry no speaker encoder and the tool says `has no speaker encoder (Base
|
||||
only)`. **Encode truncates to the hop boundary**, so the `.rvq` size is arithmetic,
|
||||
not chance: `22 × floor(samples / 1920)` bytes, which is where the recorded
|
||||
5,456–6,864 B window comes from and why the **effective crop window is
|
||||
19.84–25 s** even though the WAV law says 18–25 s. A crop shorter than that is
|
||||
refused before the extractor runs, with the number in the message.
|
||||
|
||||
The build is staged and published, never assembled in place: `reference.wav` is
|
||||
the file the façade reads, so it moves into position **last**, after the
|
||||
artifacts and the manifest. A failed extractor therefore leaves a pack directory
|
||||
that is not a voice. Nothing is ever deleted — an existing pack is refused unless
|
||||
`--force`, and `--force` moves the whole old directory to
|
||||
`/home/dank/voices/.AGENTTRASH/<voice>-<UTC>/` and builds fresh beside it.
|
||||
|
||||
Measured on the shipped `narrator1` crop (2026-10-18, `--dry-run` against the
|
||||
real source): 98.739–118.636 s → `955,378 B` of 24 kHz mono `pcm_s16le`, 19.897
|
||||
s, planned `.rvq` 5,456 B — the same byte counts the trial produced by hand, and
|
||||
the extractor itself costs 1.8–2.1 s and 1.3–1.5 GiB peak per voice.
|
||||
|
||||
## The 10-second gate
|
||||
|
||||
Project-wide source-material invariant: **the first 10 seconds of any sample
|
||||
file used to generate voices is forbidden material.** An offset that starts
|
||||
inside it is refused with exit 1 and a message that names the invariant, before
|
||||
a directory is created:
|
||||
|
||||
```
|
||||
ERROR: source-material invariant violated: the crop must start past the first
|
||||
10 s of the source file, and 'narrator1' asks for 4.5 s into … — nothing was
|
||||
written.
|
||||
```
|
||||
|
||||
The same gate is then asserted **from the manifest** that was just written —
|
||||
`.crop.offset_seconds >= .invariant.forbidden_source_seconds`, plus the recorded
|
||||
sha256 against the source it claims — so a pack cannot reach disk carrying a
|
||||
forbidden crop even if the offsets in the env file are edited into nonsense.
|
||||
`10` is not a knob: `scripts/voice-packs.env` carries the offsets, the sample
|
||||
rate, the windows and the engine facts, but the forbidden region is a constant in
|
||||
the builder. `tests/voice_pack_unit.bats` pins both halves (a refusal that
|
||||
creates nothing, and one legal crop that builds the whole pack) and applies the
|
||||
invariant to every crop in the tracked pack list.
|
||||
|
||||
## Adding a fourth voice
|
||||
|
||||
1. Pick the source file and hash it: `sha256sum /path/to/sample.wav`. A crop
|
||||
offset is a claim about one exact file, so the digest goes in the env with it.
|
||||
2. Find a speech-dense stretch **past 10 s**. The trial's recipe, applied once:
|
||||
`ffmpeg -ss 60 -t 600 -i SRC -af silencedetect=noise=-35dB:d=0.6 -f null -`,
|
||||
build the runs of non-silence, keep runs ≥ 18 s, take the longest (earliest
|
||||
on ties), and cap at 25 s. Aim for 20–25 s: shorter than 19.84 s and the
|
||||
`.rvq` falls under the floor.
|
||||
3. Add the four lines to `scripts/voice-packs.env` and the name to
|
||||
`VOICE_PACKS`:
|
||||
|
||||
```
|
||||
VOICE_PACKS="narrator1 narrator2 narrator3 narrator4"
|
||||
|
||||
VOICE_PACK_NARRATOR4_SOURCE=/home/dank/voice-sources/audiosample4.m4b
|
||||
VOICE_PACK_NARRATOR4_OFFSET=142.31
|
||||
VOICE_PACK_NARRATOR4_DURATION=24
|
||||
VOICE_PACK_NARRATOR4_SHA256=<64 hex>
|
||||
```
|
||||
|
||||
The name must be lowercase `[a-z0-9._-]`: the façade matches the directory
|
||||
name verbatim while `tts-server` lowercases names internally, so an uppercase
|
||||
name would be reported one way by the façade and another by the engine. The
|
||||
builder refuses one anyway.
|
||||
4. `scripts/build-voice-pack.sh --dry-run narrator4 /home/dank/voices`, read the
|
||||
plan, then drop `--dry-run`.
|
||||
5. `./tests/run.sh` (the pack-list invariant test covers the new row for free).
|
||||
6. Register it with the running engine. The engine's voice registry is
|
||||
memory-only and warm-on-boot, but a restart re-decodes **every** voice (6–8 s
|
||||
each), so adding one pack uses the hook instead:
|
||||
|
||||
```bash
|
||||
podman exec frank-tts-engine /app/warm-voices.sh
|
||||
curl -s localhost:7772/v1/audio/voices # the façade's list, not the engine's
|
||||
```
|
||||
|
||||
The hook walks `/voices`, registers any pack with a `reference.wav` it has not
|
||||
seen, and logs `voice <name> cold=…ms warm=…ms` to the unit's journal. The
|
||||
rootless unit restart — `systemctl --user restart frank-tts-engine.service` —
|
||||
is for when the unit or its env changed, not for a new pack.
|
||||
|
||||
## When the extractor's output size changes on an engine bump
|
||||
|
||||
The builder treats the two artifact sizes as properties of the pinned engine, so
|
||||
an engine bump that changes them **fails the build**: `reference.spk is N B,
|
||||
expected 8192 B` or `reference.rvq is N B, expected …`. That is the failure being
|
||||
loud, not a bug. Work through it in order:
|
||||
|
||||
1. Re-read the tool's own numbers rather than trusting this page: `qwen-codec`
|
||||
prints `SpeakerEncoder] Loaded: enc_dim=…` and `Pipeline] Ready: hop … , …
|
||||
codebooks @ … Hz` on every run, and the pinned tree's
|
||||
`tools/qwen-codec.cpp` documents the packing. `enc_dim × 4` is the `.spk`;
|
||||
`codebooks × code_bits / 8` bytes per frame × frames is the `.rvq`.
|
||||
2. Decide whether the new number is intended. A changed `enc_dim` means the old
|
||||
`.spk` files are unreadable by the new engine, so **every** pack must be
|
||||
rebuilt, not just the failing one.
|
||||
3. Update the four arithmetic lines in `scripts/voice-packs.env`
|
||||
(`VOICE_PACK_SPK_BYTES`, `VOICE_PACK_RVQ_MIN_BYTES`, `VOICE_PACK_RVQ_MAX_BYTES`,
|
||||
and `VOICE_PACK_RVQ_BYTES_PER_FRAME` if the codebook packing changed) **and**
|
||||
`VOICE_PACK_ENGINE_COMMIT`, `VOICE_PACK_TOOL`, `VOICE_PACK_CODEC_MODEL`,
|
||||
`VOICE_PACK_TALKER_MODEL` to the new build. An env diff that moves the sizes
|
||||
without moving the commit is the mistake to avoid.
|
||||
4. Rebuild all three packs with `--force` (the retired directories keep the old
|
||||
bytes readable beside their replacements until a human clears them), then
|
||||
restart the engine rather than using the warm hook: the hook only registers
|
||||
packs it has **not** seen, and every voice here is already registered against
|
||||
the old artifacts. `systemctl --user restart frank-tts-engine.service`
|
||||
re-warms them all from the new bytes.
|
||||
5. `./tests/voice_pack_unit.bats` — the stub in that seam reproduces the packing
|
||||
law, so it needs the same arithmetic update as the env file. The seam's
|
||||
engine-bump test is exactly this scenario with a wrong `.spk` size, and its
|
||||
assertion — no `reference.wav`, no manifest — is the property that matters.
|
||||
|
||||
## Host state (census 2026-10-18, read-only)
|
||||
|
||||
- `/home/dank/voices/` holds `narrator1`, `narrator2`, `narrator3`, each with
|
||||
`reference.wav`, a `reference16k.wav`, and a `manifest.json` **in the trial's
|
||||
own schema** (`kind: voice-reference-pack`, a silence-scan record). They carry
|
||||
**no** `reference.spk` / `reference.rvq`: the trial's artifacts live in its own
|
||||
work directory (`/home/dank/voice-audition/qwentts/voices/`, and only for
|
||||
narrator1 and narrator2). The builder's first real run is therefore a
|
||||
migration, and it should be a `--force` run per voice so the old directories
|
||||
are retired rather than left half-updated.
|
||||
- The three source files (`/home/blank/audiosample.mp3`,
|
||||
`audiosample2.m4b`, `audiosample3.m4b`, digests pinned in
|
||||
`scripts/voice-packs.env`) live on the workstation, not on Dankclaw; the
|
||||
builder reads them from `$VOICE_PACK_SOURCE_DIR=/home/dank/voice-sources`, so
|
||||
they have to be copied there once before a build.
|
||||
- `VOICE_PACK_TOOL` points at the trial's build tree
|
||||
(`/home/dank/voice-audition/qwentts/qwentts.cpp/build/qwen-codec`, checked out
|
||||
at exactly `5916bf7c`), and the two GGUFs at
|
||||
`/home/dank/models/Qwen3-TTS-GGUF/`, which is where the engine slice's
|
||||
download script puts them — that directory does not exist yet, so until it
|
||||
does the models have to come from the trial's `models/` directory.
|
||||
- Nothing is deployed: nothing listens on 7772 or 8880 today, so building packs
|
||||
is possible on that host while serving them is not.
|
||||
|
||||
## Known gaps, on purpose
|
||||
|
||||
- **No transcript in the manifest.** ICL wants a `ref_text` that matches the
|
||||
crop, and the trial's machine transcripts came back wrong ("Demon Souls" for
|
||||
*Dark Souls*). Transcribing on the host is not a fix, so the pack carries none
|
||||
and the engine registers the WAV-only voice, which is what its boot warmer
|
||||
does anyway. When ICL becomes a per-voice opt-in, the curated transcript
|
||||
belongs in this manifest — a human-supplied field, not something the builder
|
||||
can derive.
|
||||
- **No 16 kHz variant.** The packs the trial left behind carry
|
||||
`reference16k.wav` for the `llama-tts-cli` rollback engine; arm A is native
|
||||
24 kHz, so the builder emits one reference. `--force` retires the whole
|
||||
directory including that variant, so if the rollback engine is ever revived:
|
||||
`ffmpeg -i reference.wav -ar 16000 -c:a pcm_s16le reference16k.wav`.
|
||||
- **No loudness pass.** The trial's pipeline also measured and normalised
|
||||
(two-pass `loudnorm`, `astats`, `ebur128`, spectrograms) to a `-16 LUFS` spec.
|
||||
None of that is in the pack law, which asks for 24 kHz mono inside the
|
||||
duration window, so the builder does only that; a future engine that is
|
||||
loudness-sensitive should get the pass as an explicit, documented step.

|

## 2026-10-18 — voice-pack builder: the 10-second source-material gate becomes code
|
||||
|
||||
- Third slice of the voice stack (after the façade and the engine decision):
|
||||
`scripts/build-voice-pack.sh` turns a source recording plus a crop offset into
|
||||
a deployable pack — `reference.wav` (24 kHz mono `pcm_s16le`, 18–25 s), the
|
||||
engine's own `reference.spk` (8,192 B) + `reference.rvq` (5,456–6,864 B) made
|
||||
from it, and `manifest.json` provenance. Tracked tunables in
|
||||
`scripts/voice-packs.env`: pack list, per-voice source/offset/duration/pinned
|
||||
source sha256, extractor path and engine commit, artifact arithmetic. New runbook
|
||||
[[Voice Packs]].
|
||||
- **The gate is the product.** The project-wide invariant — no voice material
|
||||
from the first 10 s of a sample file — had only ever been a sentence in
|
||||
`scripts/frank-tts.env`. An offset inside it now exits 1 before a directory is
|
||||
created, and the same assertion runs again against the manifest that was just
|
||||
written, next to the recorded sha256, so a pack cannot carry a forbidden crop
|
||||
even if the env file is edited into nonsense. `10` stays a constant in the
|
||||
builder; the env file carries offsets, never the law.
|
||||
- **The extractor's contract was read, not guessed:** `qwen-codec` in qwentts.cpp
|
||||
`5916bf7c` takes `--model <codec gguf> --talker <base talker gguf> -i <wav>`
|
||||
with an optional `--device`, has **no `-o`** and names both artifacts next to
|
||||
the input with the extension swapped. So the WAV is staged under its final stem
|
||||
and `reference.wav` — the file the façade gates on — is moved into place
|
||||
**last**, after the artifacts and the manifest: a failed extractor leaves a
|
||||
directory that is not a voice. `--force` retires an existing pack whole to
|
||||
`.AGENTTRASH/` instead of touching bytes; nothing in this script deletes.
|
||||
- Sizes are arithmetic, so they are checked: 16 codebooks × 11 bits = 22 B per
|
||||
12.5 Hz frame (`22 × floor(samples/1920)`) and `enc_dim 2048 × f32` = 8,192 B.
|
||||
That makes the **effective crop window 19.84–25 s**, narrower than the WAV
|
||||
law's 18–25 s, and a too-short crop is refused before the extractor runs. An
|
||||
engine bump that changes either number fails the build by design; the bump
|
||||
procedure is in [[Voice Packs]].
|
||||
- Verified against reality, not against the model: the pinned `narrator1` crop
|
||||
(98.739–118.636 s of `audiosample.mp3`, sha256 `2299510…`) comes out of a
|
||||
`--dry-run` at 955,378 B / 19.897 s with 5,456 B of `.rvq` planned — byte-for-byte
|
||||
the trial's hand-cut numbers — and all three pinned source digests match the
|
||||
files on disk.
|
||||
- Seam: `tests/voice_pack_unit.bats` (13 tests) — refusal inside the forbidden
|
||||
region creates nothing, a legal crop builds the whole pack, `ffprobe` on the
|
||||
generated reference, manifest round-trip through `jq` with a sha that matches
|
||||
the source, re-run-without-`--force` leaves every byte alone, `--force` retires
|
||||
rather than deletes, `--dry-run` needs no extractor, a wrong-sized artifact
|
||||
from a bumped engine cannot publish a voice, and every crop in the tracked pack
|
||||
list clears the invariant. `qwen-codec` is stood in by a stub with the real
|
||||
tool's I/O shape, so no engine, no GPU, no network, no fleet host. Suite green:
|
||||
**416/416** (`./tests/run.sh`, wall 77 s) — 403 before this branch.
|
||||
- Deliberately NOT done: no transcript in the manifest (ICL wants a curated
|
||||
`ref_text`; the trial's machine transcripts were wrong, and the engine
|
||||
registers WAV-only voices anyway), no 16 kHz variant (arm A is native 24 kHz),
|
||||
no loudness pass (not in the pack law), and no pack built on the host — the
|
||||
three sources still live on the workstation and the engine GGUFs have not been
|
||||
fetched to `/home/dank/models/Qwen3-TTS-GGUF` yet, so the first real run is a

host step.
