Synesthesia Synth

An experimental audio-visual instrument that allows users to sculpt evolving spatial audio by manipulating floating capsules. Position, rotation, and pulse changes affect tone, texture, and synchronized particle generation. It's a visual synthesizer, not a game.

Synthaestesia is a free experimental audio-visual instrument. Three capsules float in space. Every contraction produces sound. Move them, rotate them, reshape their pulse — and sculpt evolving spatial audio. Position changes tone. Rotation alters texture. Delay generates synchronized particles. This is not a game. It’s a spatial synth you can see.

The artist pauses. The crowd goes quiet. Then the call comes. Raise your lights. Everyone reaches for their phone. Yours is different. The moment sound hits the microphone, your torch comes alive. It pulses with the drop, softens in the silence, breathes with everything in between. Your screen fills with visuals that move with the room. Not looping, not preset. Alive. Take it somewhere else. A campfire where the flame on your screen flickers with every crackle of wood. A house party where the disco ball scatters light to the bass. A speech where the waveform maps every word. AudioAura finds its place wherever sound fills the air. No account to create. No music library to access. Nothing stored, nothing sent. Just you, your microphone, and the room. PulseLord is for those who want more. More visuals, a unique icon, and the feeling of having the complete version.
