Walk
Put headphones on. The sounds around you pass through filters tuned to a slowly changing chord, so footsteps, traffic and wind begin to sing, with a soft space around them.
The demo is a made-up street: footsteps, wind, two passing cars and some birds.
Tap the phone or speak. If this bar doesn't move, the microphone isn't reaching the page.
The phone's own microphone is chosen automatically. Wired headphones give the shortest delay. Bluetooth headphones add a delay of their own, and using a Bluetooth headset's microphone can drop the sound to phone-call quality.
The sounds themselves ring as notes of a chord, like the Glo.
Walking sets the echo to your footsteps, and moving more brightens the sound. Standing still lets it soften.
Shape the sound
Found a sound you like? Copy your settings and paste them to Claude to make it a mood.
In the app, Walk would listen through the phone or headphone microphone live, with no recording needed. Some of the real world always stays in the mix, so people can still hear traffic.
