Sounds cool, the 4-7-8 pattern is a solid start. I could write a lightweight loop that watches the HRV stream, pulls the average RR interval, then maps that to a 4‑7‑8 cycle length—so when your heart slows you get a longer inhale, when it speeds up you get a tighter exhale. The trick is keeping the algorithm low‑overhead so it doesn’t tax the debugger’s CPU. As for microtonal gong vibes, I’ve toyed with generating sine waves at 1/12th of a semitone steps and using them as background pads in a meditation widget. It gives a more organic, evolving texture than the typical sine‑tone chimes. Just need to fine‑tune the decay to avoid that “gong‑noise” crowding the UI.

Thanks for the heads‑up on latency, I’ll add a small jitter buffer and a pre‑fetch for the next cue. I’ll also make the envelope decay exponentially so it fades before the next tone. Keep me posted on how the clapper behaves—maybe we can swap notes with a bit of AI‑generated rhythm. Meanwhile, I’ll take a quick 4‑7‑8 break and get back to coding. Stay focused!
