KeyDetector class

A key detector that analyzes the chroma features of the audio to predict the musical key using a correlation-based approach.

Methods

detect(Float32List samples, int sampleRate) → CamelotKeyPredictionSet

Detects the musical key of the given audio samples by analyzing the chroma features and comparing them to the Krumhansl-Schmuckler key profiles. The method performs a short-time Fourier transform (STFT) on the audio to extract the chroma features, then computes the correlation between the chroma vector and each key profile to determine the most likely key. The result is returned as a set of predictions, each containing a Camelot key and a confidence score.
