What if your app could turn sound into a physical experience?
Spoiler: It can. But getting there is a masterclass in VisionOS’s quirks, AI’s blind spots, and the art of compromise.
This post is part of a series of posts on Patreon for a behind-the-scenes look at building the application "Where is my mind?". This series includes code snippets, AI coding learnings, Blender/RealityKit workflows, and a deep dive into spatial audio tricks that even Apple’s docs don’t cover.
Many of these posts require paid access, and in the last post, not all could play the demo video, so this post is with free access so you can know what this app is about.
It is an AR toy, focusing on audio spatialization. It may help you to relax too. It may interest you to know more about my art, check some of my albums and videos, and then maybe decide to encourage me to do more...

Now that the app is code complete for its version 1.0, I need to get my hand on a Vision Pro so I can release it.
Meanwhile I include a few more screenshots:
