That's a good point. The model weights could be voltage levels instead of digital representations. Lots of audio tech uses analog for better fidelity.I also read that there's a startup using particle beams for lithography. Exciting times.
At least one Nobel Laureate has exactly the opposite opinion (see the Hinton lecture above)
what audio tech uses analog for better fidelity?
Vinyl records, analog tube amplifiers, a good pair of speakers 🤌
Honestly though digital compression now is so good it probably sounds the same.
speakers are analog devices by nature.
The other two are used for the distortions they introduce, so quite literally lower fidelity. Whether some people like those distortions is irrelevant.
You want high fidelity: lossless digital audio formats.
Yeah, I get very good sound out of class d amplifiers. They're cheap; they're energy efficient, and they usually pack in features for digital formats because it's easy to do.
