What they list
The notices list the software Tunedzy includes, such as FFmpeg, which runs as a separate program under the LGPL, the Whisper speech model under the MIT licence, DeepFilterNet under the MIT or Apache licence, and the other libraries the app uses.
What it means for you
You may use the bundled software under the terms in the notices. Tunedzy does not ship a GPL build of FFmpeg; the FFmpeg it uses is an LGPL build, checked when the app is built.
