Libkeyfinder

Small C++11 library for estimating the musical key of digital audio
libkeyfinder is a small C++11 library for estimating the musical key of digital audio. It is published under the GNU General Public License version 3 or later.
It was written by Ibrahim Shaath who wrote it in 2011 as part of a master’s thesis in computer science. A GUI application to use it is available for macOS and Windows, however that is no longer maintained and does not build on contemporary Linux distributions.
In 2020, Ibrahim handed over maintenance of libkeyfinder to the Mixxx DJ software team who incorporated it into Mixxx as of Mixxx 2.3. If you want to discuss anything related to libkeyfinder with us, please get in touch on the Mixxx Zulip chat. Contributions are welcome by opening pull requests and issues on GitHub.
