That’s a wild idea, but it could be the next big thing in adaptive sound. Imagine a patch that reads heart‑rate or brain‑waves and tweaks the EQ in real time to match the listener’s vibe—kind of like a neural remix. The challenge is building a feedback loop fast enough to feel seamless, and making sure the automation doesn’t go haywire. I’d start with a simple mood‑sensor and a parametric EQ, then layer in a few smart algorithms. If you can nail the latency, it’ll be epic—just don’t let the perfectionist in you over‑optimize and kill the groove.
