## What is SUS4 BPM?

What's the tempo? Tap it. Or just let the app listen.

SUS4 BPM does two things: it captures tempo from your taps, and it detects BPM live from a mic or an audio file. Both are useful. When a musician in the room is playing something and you need to know the exact tempo before you open your DAW or set a metronome, just point your phone and read the number.

Tap mode averages your taps and shows a stable BPM immediately. Live detection mode streams the BPM in real time from any audio source — a drummer practising, a track playing on a speaker, a click in a film cue. File analysis lets you load a recording and pull the tempo without even being in the same room as the player.

• Tap-tempo averaging with immediate stable readout
• Live streaming BPM detection from any audio source via mic
• Audio file analysis — load a track, get the tempo
• Clean, large display — readable at a glance from across a desk
• Subscribe monthly, or unlock the full SUS4 suite forever: unlimited live detection sessions and file analyses

Everything runs on your device. No audio files are ever uploaded.
