Doppler_effect: That's a wild idea, but totally my playground—turning feels into waves is like giving a soundtrack to a mind. The trick is capturing the randomness without it all just drowning the mix. If we could time‑warp the highs and lows of a heartbeat into frequency modulations, we’d literally hear a mood swing. The real challenge? Turning raw emotion into clean, usable data, then layering it into something that doesn't just feel chaotic, but resonates. Sound on, experimentation on.

Doppler_effect: First I’d isolate the pulse with a band‑pass filter, keeping just the heart‑rate band. Then I’d use adaptive noise cancelling—like a spectral subtraction trick—to peel away the background hiss. After that, I’d map the envelope of the cleaned pulse to a modulation source, maybe a low‑frequency oscillator that shapes a synth layer. The waveform itself becomes the lyric, but the key is keeping the signal sharp enough that the melody doesn’t just turn into static. It's a tight dance between cleaning and keeping the soul.
