What Is a Live Audio Visualizer?
A live audio visualizer draws sound as it happens. Instead of rendering a finished song into a video, it listens to a microphone or a browser tab and redraws the picture many times a second: bars rise with the bass, rings pulse on the kick, a trace follows the waveform. EzVisualizer runs the same engine as its video maker, so every style you can export also works as a live visualizer, in a browser tab with nothing to install. The usual routes to live music visualization come with catches:
- Desktop visualizer apps need an install, and some only react to music their own player opens.
- Phones won't let a web page hear another app, so phone visuals have to use the microphone.
- Mic visuals with a fixed scale sit flat in a quiet room and max out at a loud gig.
- Screensavers and player plugins ignore the beat and loop the same motion.
- Stream setups pile on plugins when a captured browser window would do.
Why Use This Live Music Visualizer
A real time audio visualizer without the install: pick an input, pick a style, go full screen.
Nothing to install
Runs in Chrome, Edge, Firefox or Safari. Open the page, allow the microphone, and it is live.
Microphone or tab audio
Use any microphone, built in or USB, or the sound of another tab in desktop Chrome and Edge, such as a web player or a DJ mix.
All 13 styles, switched on the fly
Every style the video maker exports works live. Press [ and ] to change style without stopping the music.
Levels that adapt to the room
The scale follows what it hears, so a quiet acoustic set still fills the frame and a loud club never flattens into one solid block.
Pulses on the kick
A beat detector runs on the live signal, so rings, particles and orbs hit with the kick drum, not with a timer.
Private, and free to watch
The sound is analyzed inside your browser tab and never uploaded. Watching is free, with no sign-up.
How to Start the Live Audio Visualizer
From a silent page to a live music visualizer that moves with the room, in under a minute.
In the tool at the top of this page, open the Live tab. The live visualizer waits for a sound source.
Click Microphone and allow access, or click Tab audio in desktop Chrome or Edge, choose the tab that is playing and tick Share tab audio.
Try Spectrum Bars, Circle or Oscilloscope. Pick 16:9 for a screen or 9:16 for a phone, then add colors, a logo or a title.
Go full screen on a TV or projector, capture the window in OBS, or press Record to save what you see (recording needs a plan).
Step 1 · Switch to Live
Mic, Tab, TV and OBS: Live Visualizer Setups
Four ways people run the audio visualizer live, plus recording. Each one starts from the tool at the top of this page.
Visualize mic input in real time
Click Microphone and allow access when the browser asks. EzVisualizer opens the mic with echo cancellation, noise suppression and auto gain switched off, so music reaches the visuals as it sounds instead of being cleaned up like a phone call. Put a laptop near the speaker, or pick a USB mic or an audio interface for a cleaner signal. This mic visualizer works in any current browser, phones included, and pairs with the spectrum analyzer when you want numbers rather than art.
Use the MicrophoneVisualize audio from another tab
Play music in another tab: a web player, a video, a DJ stream. Click Tab audio, choose that tab in the share dialog and tick Share tab audio. The live visualizer now follows the tab directly, with no room noise and no speaker needed. This works in desktop Chrome and Edge only, because Firefox, Safari and phone browsers don't share a tab's sound with a web page. For Spotify's web player, the Spotify visualizer walks through the same steps.
Share a TabFull screen on a TV or projector
Connect the laptop by HDMI, set the TV as an extended display and drag the browser window onto it. Press F or the fullscreen button and the live audio visualizer fills the screen with no browser bars. Mirroring the display works too. Chrome's Cast option can send the tab to a smart TV without a cable, with a short delay between the sound in the room and the picture. Pick 16:9 for TVs and most projectors.
Go Full ScreenAdd it to OBS with Window Capture
A Browser Source in OBS usually cannot show the permission prompt that the microphone or tab sharing needs, so capture the browser window instead. Open the visualizer in its own window, add a Window Capture source and pick that window. On Windows, if Chrome shows black, set the capture method to Windows 10 (1903 and up). Crop to the stage with a Crop/Pad filter or by holding Alt while you drag an edge. OBS takes the sound from its own mic or desktop audio sources; the live visualizer adds the picture.
Set Up for OBSRecord what you see
Press Record while the music visualizer is live and the stage is saved with its sound as one video file: MP4 where the browser can write it, WebM elsewhere. Recording the live output comes with a plan; watching is always free. For a polished video of a finished song, drop the file into the YouTube visualizer, which renders it frame by frame instead of in real time.
Record the VisualsA Real Time Audio Visualizer, Running Live
Four of the 13 styles, drawn by the engine this page runs. Live, they react to your microphone or tab the same way.
What you are looking at
Spectrum Bars split the sound into bands, lows on the left and highs on the right. Circle and Halo pulse on each kick the beat detector catches. Oscilloscope draws the waveform with the left channel against the right: a mono microphone draws it as a single line, while a stereo tab draws the full figure. Orb swells with the bass. Because the level scale of this real time audio visualizer adapts to what it hears, quiet music still fills the frame.
Live Visualizer Inputs by Device and Browser
What each setup can listen to. The tool only offers the inputs your browser supports, and says why when one is missing.
Desktop Chrome and Edge
Microphone and tab audio. The most flexible setup: visualize a web player directly, or the whole room through the mic.
Desktop Firefox and Safari
Microphone only. These browsers don't share a tab's sound with a web page, so play the music out loud, or open Chrome or Edge for tab audio.
Phones and tablets
Microphone only. Mobile systems keep each app's sound to itself, so hold the phone near the speaker and let the mic do the listening.
OBS and streaming
Capture the browser window. Your stream's sound comes from OBS's own audio sources, and the live sound visualizer adds the picture on top.

Who Uses a Music Visualizer Live
From a living room TV to a church projector: anywhere music plays while people watch.
Streamers
Capture the window in OBS for a music stream, a DJ set or a podcast, with a live audio visualizer moving under the camera.
Churches and venues
Run calm Orb or Halo visuals on the projector during walk-in music and worship sets. For lyrics on screen, make a worship lyric video.
Bands and rehearsal rooms
Point a laptop mic at the band and watch the low end build. Drummers like Circle for the kick; singers like Wave for the voice.
Teachers and science demos
Show what a voice or an instrument looks like as sound. For a real XY trace, open the oscilloscope online; for frequencies over time, the spectrogram.
Listeners at a desk
Keep music playing in one tab and the live sound visualizer full screen on a second monitor while you work.
Live Audio Visualizer FAQ
Setup questions people ask before they put visuals on a screen.
What is a live audio visualizer?
A live audio visualizer turns sound into moving graphics as it happens, from a microphone or another source, instead of rendering a finished file. The live mode on this page is one: the same 13 styles as the video maker, driven in real time by your mic or a browser tab. To make a video from a song file instead, use the audio visualizer on our homepage.
How do I visualize my microphone in real time?
Open the Live tab above, click Microphone and allow access when the browser asks. Make a sound and the mic visualizer reacts at once. For music, place the mic near the speaker; for a cleaner signal, choose a USB mic or an audio interface in the browser's site settings. As a mic audio visualizer it works in any current browser.
How do I visualize audio from another tab?
In desktop Chrome or Edge, play the music in another tab, click Tab audio, choose that tab and tick Share tab audio, then Share. Your live sound visualizer follows that tab until you press Stop or end the share from the browser's bar. Other browsers and phones don't offer tab audio.
Why is Tab audio grayed out?
Your browser can't share a tab's sound with a web page: Firefox and Safari don't support it, and phones and tablets keep every app's audio private. Open the page in Chrome or Edge on a computer, or use the microphone and play the music out loud.
Can it visualize Spotify or another desktop app?
On Windows, yes: in desktop Chrome or Edge, choose tab audio, pick Entire screen and tick Share system audio, and the visualizer hears the Spotify desktop app or anything else playing. On a Mac, play Spotify in its web player in a tab and share that tab, or play the app out loud near the mic.
How do I add the live visualizer to OBS?
Use Window Capture. Open the visualizer in its own browser window, start the mic or tab audio, add a Window Capture source in OBS, select that window and crop to the stage. If Chrome shows black on Windows, switch the capture method to Windows 10 (1903 and up). Keep the sound on OBS’s own audio sources.
How do I put it full screen on a TV or projector?
Connect by HDMI, extend or mirror the display, move the browser window to the TV and press F or the fullscreen button. Choose 16:9 to match most screens. Casting a Chrome tab to a smart TV works too, with a short delay.
Can I record the live visuals?
Yes, with an active plan. Press Record while live and the stage is saved with its sound as an MP4 or WebM file, depending on the browser, with no watermark. Watching the visuals stays free with no sign-up. Only record and share music you have the rights to.
Does it work on a phone?
Yes, with the microphone. Open the page in your phone's browser, switch to Live and allow the mic. Phones can't share another app's sound with a web page, so play the music out loud nearby.
Is my sound uploaded or recorded?
No. The sound is analyzed inside your browser tab, and nothing is sent to a server. Nothing is saved unless you press Record, and a recording goes straight to your device.
Which style looks best live?
Spectrum Bars and Mirror Bars read clearly from across a room. Circle, Halo and Particles hit hardest on a kick, and Orb and Wave suit calm music. Oscilloscope looks best with a stereo tab. Press [ and ] to try them while the music plays.
Why are the visuals barely moving?
The input is too quiet or the wrong one. Check that the browser is using the right microphone, move it closer to the speaker, or switch to tab audio for a direct signal. The scale adapts over a few seconds, so give a quiet room a moment.
Is it in sync with the music?
Yes. The live audio visualizer reads the sound as it arrives, with no look-ahead, so beats land with what you hear. When the picture goes through a cast or the sound through Bluetooth speakers, those devices add their own delay, and one can trail the other slightly.
What is the best live audio visualizer website?
It depends on the setup. For a microphone or a browser tab with nothing to install, EzVisualizer gives you 13 styles, full screen and OBS-friendly window capture, free to watch. Desktop apps such as projectM suit people who want endless generated presets, and OBS plugins suit streamers who never leave OBS.
Is the live audio visualizer free?
Yes, watching is free with no sign-up. Recording the live output is part of the paid plans, which also cover video downloads with no watermark.
