Tempo
120BPM
Tap a steady pulse, drag the slider, or nudge with ↑ ↓ (shift for ±10). Space starts and stops.
Meter & Feel
Open the full-screen conductor and tap a beat-point to cycle its accent — accent → normal → muted. The downbeat is accented by default.
Rehearsal
Count-in gives a lead-in before beat 1. Turn Sound off and use Flash or Vibrate to keep time silently.
Practice — Tempo Trainer
Set a start and a target — the trainer nudges the tempo a step every few bars until you get there. Target below the start and it eases the tempo down instead.
Audio Tempo Detection
—
Load a song and TEMPOrium reads its tempo and sets the metronome to it. If it sounds too fast or slow, tap Half or Double. Best on material with a clear pulse; runs locally, nothing uploaded.
Device Sync EXPERIMENTAL
Not synced.
Today: sync runs over BroadcastChannel — every TEMPOrium tab in this browser locks to the same tempo, start and stop. Open a second tab, hit Join, and try it. Next: true phone-to-laptop sync over wifi needs a tiny signalling relay broadcasting a shared start-clock; the message format is already in place, so the relay is the only piece left.
