Upload your audio files to find the key and tempo of the tracks in your library. This is a tool for DJs interested in harmonic mixing, producers looking to remix songs, and anyone trying to understand their music a little better.
Analyzes music and finds musical key.
KeyFinder is an open source key detection tool, for DJs interested in harmonic and tonal mixing. It’s intended to be very focused: no library management, no track suggestions, no media player. Just a fast, efficient workflow tool. It supports a huge range of codecs thanks to LibAV, and writes to metadata tags using TagLib.
