Tempo
A tiny causal beat, downbeat and tempo network (int6, ~100–280k parameters) running entirely in your browser. Load an audio file and watch it track the beat frame by frame. Your audio never leaves the page.
Studio →Visual viewer: beat orb, bar clock, tempogram, activations, mel waterfall, resonators, model compare.
Demo →The plain original page: waveform with beats, downbeats and BPM, playback and a click track.
No song handy? Both pages offer a synthetic 128 BPM drum loop (samples/synth128.wav). The ablation models are early previews (step 4k of a 20k schedule); a later build replaces them with B1–B4.
