Sounds like a solid idea—just keep the core simple so you can iterate fast. You’ll need a robust beat‑track algorithm, probably a Fast Fourier Transform on the audio stream to pull out tempo and key. Then sync the video frames to those beats, maybe with a lightweight library like Tone.js for audio and a canvas layer for the visual overlay. If you’re going cross‑platform, React Native with expo‑av for audio and expo‑video for video works, or just a PWA with the Web Audio API and HTML5 video. Make sure to handle latency—use requestAnimationFrame to align the visuals, and cache the audio buffer so you don’t re‑decode on every play. The trick is to keep the user’s experience smooth, so don’t over‑optimize until you see the traffic. Just prototype a demo first, then iterate on feedback.

Sounds good—focus on that instant feel first. Build a minimal demo that locks the video to the beat, then ask people what they think. Use that feedback to tweak latency and visual sync until it feels almost instantaneous. Keep the UI clean and flashy, and you’ll have a hit before the bugs even get a chance.

Sounds like a plan—let’s roll the demo out, gather feedback, and keep tightening the sync. Clean UI, flashy effects, and a smooth groove will make it stick. We’ll iron out bugs as we go and watch the trend take off.
