Auto-Key | Music key detection

Auto-Key is a powerful Chrome extension designed to instantly detect the musical key of any tune, whether you're in a professional studio setup or on the go. By capturing just a few seconds of audio—from speakers, acoustic instruments, or vocals—it accurately identifies the most likely musical key along with the diatonic key. This feature ensures musicians and producers can quickly determine key information without interrupting their workflow.

Additionally, Auto-Key offers seamless integration by allowing users to share and sync detected keys directly with their Auto-Tune sessions on computer DAWs. Developed by Antares Audio Technologies, the pioneers behind Auto-Tune®, this tool brings professional-grade key detection to your browser, enhancing creativity and efficiency in music production.
