An online audio visualizer for music and live sound

PulseKani is a free music visualizer that turns sound into moving light, particles and shapes in your browser. Bring your own audio file, microphone or browser sound. Choose from twenty-four audio-reactive scenes, from a spectrum field and oscilloscope to a particle nebula and liquid waves.

Visualize your music files without uploading them

Drop an MP3 or WAV file onto the instrument to watch your music react in real time. Playback and analysis happen on your device. Adjust intensity, switch scenes or use fullscreen for a larger view. See the music visualizer guide for details.

A live microphone visualizer for voice and instruments

Connect a microphone, sing, speak or play an instrument through a browser-visible audio interface. Each input has its own response, so multiple sources can drive different parts of a scene. Start with the microphone and instrument visualizer guide.

Make browser audio react on screen

Use Share browser audio for music, podcasts or games playing in a supported browser tab. No service login or direct Spotify or YouTube integration is built into PulseKani. Our browser-tab audio visualizer guide explains sharing and what to check if there is no sound.

Record audio-reactive visuals and save them locally

Capture audio or audio + visuals, then save the recording on your device. No account, timeline or upload is needed. For a projector or another window, use fullscreen or clean output. Recording formats and available sharing targets depend on your browser.

Music visualizer questions

Is this online music visualizer free?

Yes. You can use the visual scenes and record locally without an account or subscription. Your browser's audio, graphics and storage capabilities determine which features are available.

Can I use a microphone or instrument?

Yes. Choose Microphone / instrument. Audio interfaces, mixers and virtual devices appear when your browser exposes them. Permission is requested only when you choose the input; live inputs are not played through your speakers by default.

Can I visualize Spotify, YouTube or another browser tab?

Choose Share browser audio, select an audio-capable tab or target, and enable its audio-sharing option. PulseKani does not integrate with these services or extract their media. Sharing availability depends on your browser and system.

Can I use my own music files?

Drop an audio file onto the instrument or choose Open audio file. MP3, WAV and other formats your browser can decode work locally. More sources also offers direct Internet streams.

Is my audio uploaded?

No selected audio is uploaded to PulseKani for processing. Analysis and recording happen on your device. Internet streams are fetched directly from their provider; the public host receives normal page requests and may collect page-performance analytics.

Can I record the visuals?

Yes. Press Record, accept Audio + visuals, then Start. Stop and save when finished. More options lets you choose sources, size and destination. Available formats and long-session limits depend on your browser and storage.

Which browser works best?

Desktop Chrome is the primary tested browser. Other Chromium browsers may work; sharing and recording capabilities vary. WebGL2 is required for live visuals. Mobile support is more limited, particularly for sharing audio from another app or tab.
