# Third-party notices

## MakeHuman teeth_base

Dentaphone's optional WebGL jaw adapts the MakeHuman system `teeth_base`
asset. The source contains 32 independent tooth shells and a connected mouth
shell:

- https://static.makehumancommunity.org/assets/assetpacks/makehuman_system_assets.html
- https://static.makehumancommunity.org/about/license.html

MakeHuman released its system assets under CC0 1.0 Universal. Morphazoid
separates and names all 32 teeth, splits the mouth shell into independently
hinged upper and lower sections, recenters and scales the geometry, and converts
it to GLB. Source details and the exact OBJ hash are in
`assets/models/dentaphone-chomper.LICENSE.txt`.

The reproducible converter lives only in the Morphazoid source repository at
`scripts/build-dentaphone-chomper.py`; it is a build and provenance tool, not a
runtime dependency, and is intentionally omitted from published static-site
bundles. References to that path in the model's license notice refer to a
repository checkout.

## Gilbert generalized Hilbert curve

Paths adapts the recursive two-dimensional Gilbert reference algorithm:

## Bioacoustic recordings

The built-in recording menus bundle twelve unchanged Ogg Vorbis or PCM WAV field
recordings from Wikimedia Commons. Full provenance, recording notes, source
links, license links, and file hashes are recorded in
`assets/bioacoustics/SOURCES.md`.

- Thrush nightingale, common blackbird, and chaffinch recordings: Oona
  Räisänen (Wikimedia Commons user Mysid), public-domain dedications.
## WebGPU Chiptune / Chiptune (sound) lineage

WebGPU Chiptune translates the active sound path of **Chiptune (sound)** by
srtuss (2015), Shadertoy shader ID `MljSRt`, from GLSL into WGSL and adds the
Morphazoid streaming runtime, controls, presets, visualization, and host state
adapter.

- Original shader: https://www.shadertoy.com/view/MljSRt
- Author credit in the supplied source: `srtuss, 2015`

The Shadertoy page is not loaded at runtime. The supplied shader text and
archived metadata did not state a reuse license, so this notice records
provenance without asserting license terms.

- House cricket recording: Wikimedia Commons user Morray, CC BY 3.0.
- Field cricket recording: Wikimedia Commons user Thatcher, CC BY-SA 3.0.
- European field cricket recording: Baudewijn Odé, CC BY-SA 4.0.

Morphazoid distributes the Creative Commons recordings unchanged, preserves
attribution and license links, and does not suggest endorsement by the
recordists or licensors.

No Indigenous or other human song recordings are redistributed. Links in the
Acoustic Manifold archive directory are discovery references, not licenses to
copy, train on, rearrange, or resynthesize their holdings. Record-level rights,
community authority, culturally sensitive access protocols, and any Traditional
Knowledge Labels remain applicable.

## Three.js

Dentaphone, Nightingale Manifold, and Acoustic Manifold vendor Three.js 0.185.1
for local, offline-safe WebGL rendering. Dentaphone also vendors the GLTFLoader
utilities needed by its anatomical jaw:

- https://threejs.org/
- https://github.com/mrdoob/three.js

Copyright © 2010-2026 three.js authors

Three.js is MIT-licensed. The complete license text is in
`vendor/three/LICENSE.txt`. Dentaphone's vendored loader utility imports were
changed only to point at the adjacent local Three.js ESM build.

## Fluid Music Open Drums / Hyperreal TR-808 and TR-909 samples

Sample Drums references version-pinned WAV files from the Fluid Music
open-drums npm packages at runtime:

- https://www.npmjs.com/package/%40fluid-music/tr-808
- https://www.npmjs.com/package/%40fluid-music/tr-909
- https://github.com/fluid-music/open-drums

The TR-808 package is ISC-licensed and its README says the original Hyperreal
samples were recorded by Michael Fischer with no licensing restrictions noted.

The TR-909 package README says the samples were recorded by Jason Baker / Rob
Roy Recordings and reproduces the original Hyperreal text allowing free copying
and distribution while prohibiting distribution of the samples for profit.
Because of that condition, Morphazoid does not vendor the TR-909 WAV files in
this repository; it references the pinned package URLs from the browser and
decodes them into memory during use.

## WebGPU 303 / Acid Synth lineage

WebGPU 303 adapts the local WebGPU Audio Acid Synth shader and streaming
architecture. That local demo credits its acid voice lineage to:

- sound - acid jam by srtuss on Shadertoy
- https://www.shadertoy.com/view/ldfSW2

Morphazoid keeps that attribution visible on the WebGPU 303 page and does not
load the Shadertoy page as a runtime dependency.

## srtuss WebGPU master synth and Sound archive

The sound-only srtuss instrument contains WGSL translations of ten original
Shadertoy Sound passes by srtuss:

- MljSRt — Chiptune (sound)
- XdSGz1 — noir et blanc (sound)
- Xd2GW3 — Industry II (sound)
- 4tsGD8 — Boulder Dash title (sound)
- ldlfRS — Shift (sound)
- lldGDM — Noise Bands (sound)
- ltKSRc — Gravity Shielding (sound)
- 4tdSDB — DnB (sound)
- MslBR4 — Cipher (sound)
- ldfSW2 — sound - acid jam

Original project pages are under:

- https://www.shadertoy.com/user/srtuss
- https://www.shadertoy.com/view/SHADER_ID

Nine exact Sound-pass source strings were recovered from the public
GabeRundlett/shadertoy-api-shaders JSON archive pinned at commit
f6d538adf936215ccf2d11ba9b4a6c79ccb448c5. Acid Jam was recovered from an
author-attributed SimpleShader copy and independently corroborated against an
audiojs copy whose executable GLSL matches after normalizing its wrapper-only
entry-point and helper rename:

- https://raw.githubusercontent.com/mike-seger/simpleshader/3d0593e14bbd585b3eb88d042a3bf251af6c4b63/shaders/shadertoy-gpu-audio/sound-acid-jam-sound.glsl
- Primary source SHA-256: 1f6c0e5cfb9577681ca79843907ab7f061427fc1a8e35b5d292d3ee8a01b456a
- https://raw.githubusercontent.com/audiojs/audio-shader/f8de3cd2ddf231198ae7d7aa367bae25d01ed453/test/sounds/acid.glsl
- Corroborating source SHA-256: f889afecc6270358227964d7fe6f2ac2ea714822ef1eefdf9751da4320cf4cd2

Each WGSL module records its original source length and SHA-256 digest, pinned
source URL, translation notes, and project URL.

The exact translations remain separately selectable. Morphazoid also derives
parameterized Master variants from XdSGz1, Xd2GW3, ldlfRS, 4tsGD8, lldGDM,
ltKSRc, 4tdSDB, and MslBR4. Those variants expose source-native component
levels and mapped performance controls; they retain the same attribution.
Chiptune (MljSRt) and Acid Jam (ldfSW2) remain exact-only on this page because
Morphazoid provides dedicated WebGPU instruments for those two systems.

Morphazoid treats these Shadertoy adaptations under the site's
Creative Commons Attribution-NonCommercial-ShareAlike 3.0 publication terms
and preserves the noncommercial/share-alike restriction:

- https://creativecommons.org/licenses/by-nc-sa/3.0/

The standalone Chiptune notice above separately records that its supplied code
and mirrored JSON do not embed a per-file license declaration; this archive
does not represent that absence as a more permissive license.

The texture sampled by Noise Bands, Gravity Shielding, and DnB is the exact
512 × 512 Shadertoy “Pebbles” channel asset, recovered from mrRay/VVISF-GL
at commit 7306b1abdd0b5536f0f230c0519453e79184e08b:

- https://raw.githubusercontent.com/mrRay/VVISF-GL/7306b1abdd0b5536f0f230c0519453e79184e08b/examples/Qt/ISFEditor/ISFEditor_app/ISFConverter/shadertoy_textures/ad56fba948dfba9ae698198c109e71f118a54d209c0ea50d77ea546abad89c57.png
- Vendored file SHA-256: 4d0c9886f97a362824c1e21d26ff40a16469564c4ad7e0ce73aab5b392541b04

Three further Sound projects (MdXXW2, Xd2XDm, and 4ddfWX) stay
marked source-pending because accessible copies are absent, incomplete, or
conflicting. A separate VEDA acid shader describes itself as heavily inspired
by ldfSW2; it is not used or represented as the 1:1 source.
The fourteen image-only srtuss projects are inventoried but are neither bundled
nor rendered.

## XYFlow comparison renderer

The optional `?graph=xyflow` renderer for Modular WebGPU Synth statically
bundles React Flow and its browser dependencies. It is loaded only for that
comparison route; the original Morphazoid graph renderer remains the default.

- React Flow / XYFlow: https://github.com/xyflow/xyflow (MIT)
- React and React DOM: https://github.com/facebook/react (MIT)
- Zustand and classcat (MIT)
- D3 selection, drag, zoom, transition, interpolation, dispatch, timer, and
  color modules (ISC), plus d3-ease (BSD-3-Clause)

Every production build generates the complete dependency license texts from
the installed, lockfile-pinned packages at
`assets/xyflow/THIRD_PARTY_LICENSES.txt`.

## Pink Trombone

The shared classic 44-section vocal-tract geometry used by Throatazoid, Pink
Trombonazoid, Spelling Synthesizer, and Hiccup Head, including its tongue-rest curve,
reflection coefficients, and two-step waveguide behavior, is adapted from Neil
Thapen's Pink Trombone:

## ffmpeg.wasm

FFmpeg Wasm Lab vendors the official `@ffmpeg/ffmpeg` browser wrapper version
0.12.15 under the MIT license. Its complete license is included at
`vendor/ffmpeg-wasm/LICENSE`.

After explicit user action, the page fetches the single-thread ESM build from
`@ffmpeg/core` version 0.12.10 directly from unpkg and verifies the exact
response bytes before executing them:

- `ffmpeg-core.js`: https://unpkg.com/@ffmpeg/core@0.12.10/dist/esm/ffmpeg-core.js
  - SHA-256: `67a48f11645f85439f3fde4f2119042c16b374b910206b7a7a24f342e28dcae3`
- `ffmpeg-core.wasm`: https://unpkg.com/@ffmpeg/core@0.12.10/dist/esm/ffmpeg-core.wasm
  - SHA-256: `9f57947a5bd530d8f00c5b3f2cb2a3492faa7e5d823315342d6a8656d0a6b7b7`

Morphazoid's repository and release artifacts do not contain those core object
files. Only the pinned core assets are requested from unpkg; captured microphone
PCM stays inside the browser worker and is not sent to the CDN.

The core package declares `GPL-2.0-or-later`; its GPLv2 text is retained at
`vendor/ffmpeg-wasm/core/COPYING.GPLv2`. Runtime provenance and upstream
source/build references are recorded in `vendor/ffmpeg-wasm/core/README.md`:

- Package: https://www.npmjs.com/package/@ffmpeg/core/v/0.12.10
- Source/build reference: https://github.com/ffmpegwasm/ffmpeg.wasm/tree/71aa99d37c02a7b4c435275ca9ef50e612f6efa1

## CMU Flite / KAL16 diphone voice

The Spelling Synthesizer diphone audio sprite was generated from the
`cmu_us_kal16` diphone voice in CMU Flite 2.2, then silence-trimmed, faded,
level-normalized, and packed by Morphazoid. These processing and packaging
changes are not endorsed by Carnegie Mellon University.

## OddVoices CC0 voice recordings

Vocalzoid includes compact audio sprites derived from the Air, Cicada, and
Quake voice recordings in OddVoices. Morphazoid extracts only eight labelled
English units per voice, trims long vowel bodies, removes DC offset, normalizes
level, adds short edge fades, and packs the units into browser-sized WAV files.
These packaging changes are not endorsed by the OddVoices authors. The
reproducible builder is `scripts/generate-vocalzoid-oddvoices.py`.

## CMU ARCTIC voice recordings

Vocalzoid includes five compact audio sprites made from the BDL, CLB, JMK,
KSP, and SLT voices in the CMU ARCTIC 0.95 releases. These files are modified
excerpts, not the original voices: Morphazoid selects eight automatically
aligned phone units per speaker, trims them to the “vocalzoid” demo inventory,
removes DC offset, normalizes level, adds edge fades, finds phase-matched vowel
loops, and packs the results into browser-sized mono WAV files. The original
authors do not endorse these modifications. The reproducible builder is
`scripts/generate-vocalzoid-arctic.py`.
