"The new device is built from arrays of resistive random-access memory (RRAM) cells.... The team was able to combine the speed of analog computation with the accuracy normally associated with digital processing. Crucially, the chip was manufactured using a commercial production process, meaning it could potentially be mass-produced."

Article is based on this paper: https://www.nature.com/articles/s41928-025-01477-0

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.
