Download matching source/build/relink materials for ZoneBuilder’s LAME 3.100 / wasm-media-encoders 0.7.0 encoder.
The archive includes readable source, the original build files, licenses,
SHA-256 checksums, explicitly historical published references, and rebuild-mp3.py with
instructions in its README.md. It does not install or execute itself.
It is available at the same application-relative address for a root or
GitHub Pages subpath deployment and needs no authentication.
manifest.json records the download’s size/hash, each packaged
file hash/origin, and the current application runtime artifact hashes.
The current WASM was built from this package. Its SHA-256 is
a1d8ba08c80ec5e63d62ad30685e9656c9032126e9cd3b9c95991f8e17083b68.
Reproducibility evidence binds the exact source
archive to the documented clean rebuild and byte-identical current runtime.
Verify the downloaded archive before extraction against that manifest; then
run sha256sum -c SHA256SUMS or shasum -a 256 -c SHA256SUMS inside it.
Use Emscripten SDK 2.0.8 and its recorded Node runtime for the MP3-only helper. The source package explains the historical macOS SDK version-label mismatch. Detailed identities, validation and limits: Build provenance. License/recipient rights: Third-party notice.
This download is available separately from normal playback/startup. It is not precached or imported as executable app code. Explicit downloads can be cached by the existing service worker. Keep matching source and notices alongside every version of the encoder offered to recipients; retain older packages when retaining their binaries. There is no automatic pruning or written-offer fulfillment service.
