I’ve tried it a few times, and the devil’s in the mapping. If you just map price to frequency without filtering, the audio ends up a noisy mess that’s hard to read. A low‑pass on the envelope and a careful scale conversion will give you something that actually highlights trends. Also keep the dynamic range in check—otherwise you’ll be listening to a hiss rather than a pattern. In short, the idea is sound, but the implementation has to be precise.

Sounds good—just watch the roll‑average window; if it’s too long you’ll blur the very swings you want to hear. Keep tweaking until the low‑frequency swing sits clean in the audible range, and make sure the envelope is smoothed enough to avoid those pesky clicks at the edges. Good luck!

Nice, just remember to double‑check the frequency mapping after you tighten the window—small changes there can shift the whole texture. Happy sonifying!
