Tuning Analyzer

Your recording. Your tuning. Your instrument. Record vocals, instruments or music, or open an audio file. Tuning Analyzer estimates the best-fitting concert pitch and major or minor key. The built-in chromatic tuner automatically adopts the estimated A4 reference, so you can tune your instrument to the recording and play along. LIVE CHROMATIC TUNER Play a single sustained note to see its note name, octave, frequency and deviation in cents. Adjust the reference independently of playback from 220 to 880 Hz in 0.1 Hz steps. RECORD AND ANALYZE Record up to 60 seconds with the microphone or select an audio file. Analysis is available for recordings of at least 8 seconds. For vocals, we recommend 15–30 seconds with several clear notes. Try the included audio demo to get started. LISTEN, RETUNE AND EXPORT After analysis, playback starts at the original tuning. Adjust the target reference and compare with A/B. Keep the tempo constant or let it change with pitch. Export your retuned audio as WAV. LOCAL AND MULTILINGUAL Audio is processed on your device. No account, audio uploads or advertising. The live tuner does not save recordings. Available in German, English, Spanish, French and Simplified Chinese. ABOUT THE MEASUREMENTS Analysis results are estimates. A 0.1 Hz adjustment step does not guarantee measurement accuracy of 0.1 Hz. Without known notes, the A4 reference is ambiguous by whole semitones; automatic estimates stay near 440 Hz. Mixed tunings, vibrato and noise can affect results. A single note cannot establish a unique musical key. The tuner measures individual notes in equal temperament. Retuning at a constant tempo may introduce audible artifacts. Changing tempo changes the duration. Supported file formats depend on your device. Record and process music and people only with the necessary rights and consent. Tuning Analyzer is for musical analysis, entertainment and sound design. It does not determine a bodily frequency or promise health benefits.
