Audio Spectrum
A MiniMeters-style analysis strip running entirely in the browser. Ten toggleable modules: scrolling spectrogram, waveform history colored by spectral content (lows red, mids green, highs blue), peak/RMS meters, a BS.1770 loudness panel (momentary / short-term / integrated, loudness range, 4x-oversampled true peak), loudness history with streaming target lines, goniometer, correlation meter, triggered oscilloscope, a dual-FFT spectrum analyzer with a note/cents readout, and a BPM detector ported from BPM Lab, with tap tempo. Drag modules to rearrange and resize; freeze any moment to inspect it. Feeds on mic, an audio file (drop one anywhere), or a built-in generative beat. All DSP runs locally in an AudioWorklet — no audio ever leaves the page.
