MP3: LAME via lamejs 1.2.1 (Alex Zhukov; based on LAME / jump3r)
Project: https://lame.sourceforge.net/
Project: https://github.com/zhuker/lamejs
License: LGPL-3.0, as declared by the upstream package.
Unchanged acknowledgement: lamejs-LICENSE.txt
Full texts: LGPL-3.0.txt and GPL-3.0.txt
Legacy notice retained from upstream Java source: LAME-legacy-COPYING.txt
Local corresponding source: lamejs-1.2.1-source.zip
Immutable commit: 32f6198fc9d7dc69894977152a08442607738c40

The source archive contains the preferred JavaScript source, readable browser
bundle, exact deployed minified bundle, Java reference source, original notices
and build scripts. Encoder code has not been modified. Unneeded test recordings,
demonstration pages and PNG images are excluded; no user recording is included.
The source notes inside the archive describe the selection and how to rebuild
or replace the encoder. The upstream tag's package.json retains version 1.2.0;
the 1.2.1 tag and byte-identical runtime match identify this release.

PPUTROLL permits library modification and reverse engineering of the
application for debugging those modifications, including making a local
application copy needed for that purpose. Replace vendor/lame.min.js in a
local copy with an interface-compatible browser library, or the readable
lame.all.js under that filename, and serve the site with an HTTP static
server. Browser Local Overrides can substitute that response locally too.
No application runtime integrity restriction prevents this replacement.
The application uses lamejs.Mp3Encoder. Complete build and replacement notes
are in PPUTROLL-SOURCE-NOTES.txt inside the source archive.

The official release symbol map confirms linked math, standard-library and
compiler helper functions. The additional math notice file identifies the
corresponding source files and preserves their full original license comments.
No claim is made that every toolchain component is embedded. The LLVM exception
for compiler-embedded object portions is retained in its original license;
these notices do not add requirements to exported recordings. The linked
dlmalloc 2.8.6 allocator by Doug Lea is dedicated upstream to the public domain
with a reference to CC0 1.0; Emscripten adaptations retain upstream licensing.

The authors' names do not imply endorsement of PPUTROLL. The complete license
texts govern the covered components. These notices do not assign an open-source
license to unrelated PPUTROLL application code or grant rights in uploaded or
exported audio. Preserve these files and source availability when distributing
or deploying the corresponding runtime files.
