Guitar visualizer: plug in and watch the strings
Plug a guitar into your audio interface — or just play in front of the microphone — and BLOOB draws what you play: the pick attack, the harmonic stack of a chord, the decay of a note. Free, in the browser, nothing installed.
Who this is for
- Guitarists streaming practice or looping sessions
- Players who want a visual behind a playthrough video
- Anyone curious what their tone actually looks like
Interface or microphone, both work
Click “Mic / instrument” and choose your interface as the input device in the browser prompt. Echo cancellation and noise suppression are switched off, so a pick attack stays a pick attack instead of being smoothed away. An amp in the room and a laptop microphone work too: the noise floor is measured from your setup in a couple of seconds, so room hum does not fire false beats.
Scenes that suit a guitar
Oscilloscope and Phase Scope draw the waveform itself, so you can watch a note bloom and decay. Spectrum Bars and Radial Spectrum show the harmonic stack — the reason a bridge pickup looks different from a neck pickup. String Rig has twenty-eight strings that pluck by register, and Signal Ridges turns a held chord into a landscape.
It never touches your tone
BLOOB only listens. The input is analysed and never routed back to the speakers, so there is no feedback loop and nothing is added to your monitoring path. Your amp, pedals and interface behave exactly as they did before.
How to do it
- Connect your guitar to your audio interface, or stand near the microphone
- Open BLOOB, click “Mic / instrument” and pick that input device
- Press ← → to find a scene — Oscilloscope, String Rig and Spectrum Bars read best
- Press Record for a clip, or H to hide the controls and play fullscreen
Questions people ask about guitar visualizer
Do I need an audio interface?
No. A laptop or USB microphone in front of an amp works. An interface gives a cleaner, louder signal with fewer room reflections and less bleed.
Will it tell me which chord I am playing?
Not by name — it is not a tuner or a chord detector. It shows the sound: the fundamental and its harmonics in the spectrum, the attack and decay in the waveform, low notes at one end and high notes at the other.
Can I record the video with my playing?
Yes. Record captures the canvas together with the live input; export MP4 or WebM at up to 4K.
Does it work for bass guitar?
Yes, and it is very visible: sub and low-mid energy drives size and gravity in most scenes. Try Liquid BLOOB or Deep Sonar.
