How It Works
Our trumpet 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 partial in your selected instrument 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.
