LAME

Source offer for LAME, licensed under LGPL-2.0-or-later and shipped in Morphjet's ai-tts pack.

Note: mp3 encoder — standalone on macOS and Linux, via the in-pack FFmpeg on Windows

Corresponding source

Morphjet distributes LAME as a bundled subprocess. Under LGPL-2.0-or-later we publish its complete corresponding source for download at no charge: the exact upstream version we built from, plus any Morphjet patches and the build/relocation scripts used to produce the shipped binary.

Free to anyone; a quick anti-bot check guards the file. The archive holds every version listed below, so it matches whichever build you received.

Versions shipped

Morphjet does not ship one version of LAME everywhere — each platform's build channel pins its own. The archive above contains the corresponding source for every row here.

Version	Shipped in	Built from
`3.100`	`ai-tts/linux-x86_64`, `ai-tts/macos-aarch64`, `ai-tts/windows-x86_64`, `media/linux-x86_64`, `media/macos-aarch64`, `media/windows-x86_64`, `ai-stt/linux-x86_64`, `ai-stt/macos-aarch64`, `ai-stt/windows-x86_64`, `ai-stems/linux-x86_64`, `ai-stems/macos-aarch64`, `ai-stems/windows-x86_64`	standalone `lame` for Kokoro's wav→mp3 step on macos (Homebrew `lame`, relocated by scripts/bundle-kokoro-macos.sh) and linux (conda-forge `lame`); Windows encodes mp3 through the in-pack FFmpeg instead. Every shipped FFmpeg additionally links libmp3lame. Version read out of the SHIPPED binaries on both platforms (`LAME 64bits version 3.100` / `LAME3.100`), not off a build box — this Mac's Homebrew has since moved to 4.0, so asking it would have given the wrong answer.

Upstream project (reference only — upstream removes old releases, which is why we host the source ourselves): https://lame.sourceforge.io/download.php

The full text of the LGPL-2.0-or-later license ships inside the pack (share/licenses/lame) and is reproduced in the app's About screen. The version you are running is shown there too. The source stays available for as long as we distribute this build. Not legal advice.
