Real-Time Audio Analysis

Frequency visualization, automatic BPM detection and precise synchronization.

// Audio analysis
analyserNode.fftSize = 2048;
analyserNode.getByteFrequencyData(dataArray);
drawWaveform(ctx, dataArray);

Multi-Deck Interface

Up to 4 virtual decks with independent controls and crossfader.

const decks = {
    a: new Deck('a'),
    b: new Deck('b'),
    c: new Deck('c'),
    d: new Deck('d')
};
