Audio Chord/scale Detector
Upload a clip or use the microphone to estimate the played chord/scale from a compact frequency-analysis workflow.
Analyse an audio source, compare its strongest chord or scale candidates, and open the matching key-scale practice view when one result is useful.
Provide the sound to identify
- Load or record an audio source and run the tonal analysis.
- Compare the candidate list and adjust the slice or search settings if the result is ambiguous.
- Open the candidate in the instrumented view and test it against the recording.
Detection settings
Choose the detection type, the number of matches, and the bass constraint.
Audio source
Choose an input mode, adjust the detection constraints, then compare the most likely matches.
Upload a short audio excerpt and analyze the played chord/scale from its frequency content.
Detected matches
The strongest matches appear here with confidence, estimated bass, and a compact harmonic preview.
Analysis is waiting for a source
Upload an audio excerpt or start realtime listening to begin the harmonic analysis.
From recorded sound to a tonal choice
Upload a clip or use the microphone
The detector slices the source, scores possible tonal centers and collections, and keeps multiple candidates visible instead of hiding uncertainty.
Compare chord and scale candidates
A candidate becomes musically useful when you audition it, compare it with the passage, and continue in the instrumented key-scale workspace.
Verify the candidate against the passage by ear
- Load or record an audio source and run the tonal analysis.
- Compare the candidate list and adjust the slice or search settings if the result is ambiguous.
- Open the candidate in the instrumented view and test it against the recording.
