Generated from the build · 74 components
Pitcheon is built on work other people gave away. Every component bundled with the app is listed below, grouped by licence. The full licence texts ship inside the app — About → Licences — and alongside the source.
ffmpeg
Pitcheon bundles an LGPL build of ffmpeg, configured without
--enable-gpl and without libx264 or libx265, and invokes it as a
separate process. Under the LGPL you are entitled to the source and to the
means to relink it; both are available on request and alongside the app's
source.
Model weights
The separation, pitch and transcription models are downloaded from their original homes on first use rather than redistributed here. All three are MIT licensed.
