Upload a clip or use the microphone to estimate the played keyscale from a compact frequency-analysis workflow.
The Audio KeyScale Detector listens to an audio excerpt, builds an octave-folded frequency profile, then compares that signal against known keyscale fingerprints.
The same experience supports two use cases: upload a file for a stable reading, or start realtime listening to test a voice, instrument, or short harmonic gesture.
The interface stays intentionally compact: audio source, detection constraints, signal level, and a ranked list of the closest matches.
This experience connects audio capture, frequency analysis, bass estimation, and keyscale detection inside one focused tool.

Example
Example: start from a simple musical idea, hear it, compare its function, then open a related page for deeper work.
The page first names the useful musical action.
Controls help verify a precise sound idea.
Related pages continue the same musical thread.
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.
JolyEngine audio input:
Default global microphone
Upload a short audio excerpt and analyze the played chord/scale from its frequency content.
Select a short audio file to start the analysis.
Detected matches
The strongest matches appear here with confidence, estimated bass, and a compact harmonic preview.
Idle
Analysis is waiting for a source
Upload an audio excerpt or start realtime listening to begin the harmonic analysis.
