Built for live sound, not video editing

Unlike video renderers or template-based clip makers that require lengthy exports, PulseKani is a live instrument. Sound happening now becomes motion now. Whether you are listening with headphones, performing at a live venue, projecting onto a wall, or streaming to an audience, visuals render in real time at 60 frames per second using native WebGL2.

Your music files stay private

Drop an MP3, WAV, FLAC, OGG, or AAC file onto the visualizer. Playback and DSP frequency analysis happen directly in your browser using the Web Audio API. Your selected music files are never sent to a cloud server.

Go fullscreen or clean output

Press F for immersive borderless fullscreen on any monitor, TV, or projector. Or open a dedicated Clean Output window that isolates the visuals from controls for clean recording and multi-monitor setups.

Multi-source intelligence

Connect more than one sound source at once. Run a backing track from a file while singing through a live microphone. Scenes like Collision and Source Constellation animate the distinct signals independently.

Capture live performance

Record your live performance session locally as an audiovisual WebM or high-fidelity WAV file. Recording captures the exact live interaction without converting the instrument into an editing studio.

How to visualize your music in 3 steps

  3. 3. Go fullscreen or capture
