Spectrum
See a signal as a live 3D spectral LANDSCAPE — a real-time waterfall of its frequency content that scrolls as it plays (bass blue → treble red). An ANALYTICAL pass-through: wire a source (or a whole chain) into its input and its output onward (e.g. to the Speaker), and the audio flows through UNTOUCHED — the analysis is a zero-latency side-tap. The first of the Analysis family (visual signal indicators). The FFT lives in the kernel (chroma::spectrum); audio.js only taps the raw samples it owns.
