How It Works
Our cello tuner uses an autocorrelation-based pitch detection algorithm to accurately identify the frequency of the note you play. It then matches the detected pitch to the closest string in your selected tuning and shows you exactly how many cents sharp or flat you are from the target note. All audio processing happens locally in your browser — nothing is recorded or sent to any server.

We believe that every cello player deserves access to a high-quality tuning tool. That's why we've created a free, accessible cello tuner that works for everyone — from beginners picking up their first cello to seasoned players exploring alternate tunings.
