A beat visualizer that separates the drums
BLOOB detects kicks, snares and hats separately and shows you the groove: one bar per revolution on Deep Sonar, a scrolling drum score on Pulse Lanes, struck pendulums and plucked strings.
Who this is for
- Drummers and producers checking a groove
- Dancers and choreographers counting bars
- DJs beat-matching visually
Three onset detectors
A dedicated unsmoothed analyser measures spectral flux in the kick band (40–350 Hz), the mid band for snares and stabs, and the high band for hats, each with an adaptive threshold — so a hi-hat never fires the kick visual.
See the bar
Deep Sonar sweeps once per bar at the detected tempo and marks each hit in its own lane at the angle it landed, so you can see whether the kick sits on the grid. Pulse Lanes scrolls the same hits as a score.
Predictive sync
Once the tempo is locked, visual beats fire a few milliseconds early to cancel pipeline latency, and the lead adapts to your output device — including Bluetooth.
How to do it
- Open BLOOB — nothing to install, no account
- Choose a song, or use your microphone or a browser tab
- Pick a scene, a mood and a palette
- Press Record (or Export MP4) and download your video
Questions people ask about beat visualizer
How accurate is the tempo?
Within a BPM on most produced music; tap tempo and a lock are there for edge cases like half-time feels.
Can I see the beat grid?
Deep Sonar and Pulse Lanes draw it. The BPM shows in the top bar with a beat LED.
What about live drums through a mic?
Works well — the noise floor is self-calibrating so room noise does not fire beats.
Does it flash on every beat?
Only if you turn on Pump or Shake. By default the scenes move; the frame stays still.
