Scientists found a way to make cold brew in a few hours just recently. It even passed every blind taste test, too. I forget the machine name, but it's also commonly used to clean jewelry, as well as use in a lab, for like $60.

Edit: I went and found the old article, they used ultrasonic waves and it only took them 1-3 minutes depending on preference. Unfortunately after reading another article, it's a modification they made to existing espresso machines. Their initial machine was around £15,000, and was overkill. Not sure how someone would be able to replicate at home. 🥲

Ultrasonic cleaner? It basically vibrates like a speaker at high frequency, and when in water it can be used to clean jewelry.

If you find it, post it!

It's not really an inconvenience for me; I set it up, let it brew overnight; easy-peasy.

Ultrasound? I have one of those I use to clean all sorts of things. Never thought of using one for coffee, but I could see it really rendering the oils, even cold.
