Browser chunks include source maps with their corresponding source. Build
materials (application frontend source, configuration and dependency lock)
are also available under /third-party/rebuild/ at the same paths as the project.
To recombine with a modified AAC library, download those files, use Node >=24.14
and pnpm, edit patches/aac@0.1.3.patch (or use pnpm patch aac@0.1.3), run
pnpm install --no-frozen-lockfile, then pnpm build:web. Host dist/web with the
same backend. Native speaker is not used; its build remains disabled.
Do not restrict modifications of this library or reverse engineering for
debugging such modifications. Sources and notices must accompany deployment.
Private .env, API source, database and uploaded audio are not included.

@audio/encode-aac 1.2.1: MIT AND FDK-AAC. We added a software encoder option
on 2026-10-11 for deterministic priming; the FDK codec itself is unmodified.
Wrapper source and licenses: /third-party/encode-aac/
Original build sources: /third-party/encode-aac/encode-aac-build-source.tar.gz
audiojs/encode revision: 53b33676025892cfd69b60738d642f0eb4469d59
Complete unmodified FDK source: /third-party/encode-aac/fdk-aac-source.tar.gz
mstorsjo/fdk-aac revision: 716f4394641d53f0d79c9ddac3fa93b03a49f278
The shipped WASM matches this build source byte-for-byte. Restore the FDK
source under encode-aac/lib/fdk-aac and use build.sh with Emscripten to rebuild.
