For the Pi, you can use either a zero-w (be careful, there's a zero non-w which doesn't have wi-fi), a Pi3, or a Pi4. I got mine from the PiHut. Get an SD card that's a decent size, 8GB is more than enough.
You burn the OS using the burner available on the Raspberrypi.org website, put it in the Pi and connect the pi to a keyboard, monitor and mouse. From there you enable wifi and follow the step by step instructions to install both minidsp-rs and ezBEQ.
A couple of things to bear in mind:
- ezBEQ works differently to BEQd, there's no merge anymore. You'll load your room eq and house curve to the output and leave the input empty. ezBEQ will manage the input only and not touch the output.
- If you try to use multiple sources of input (minidsp plug-in, ezBEQ web, ezBEQ app) things can get confusing. A simple workflow is to load your data using the minidsp plug-in and then close that and don't touch it again. From then on just use ezBEQ web.
You can apparently set it up so that you can use both, but unless you have a need to I wouldn't.
The ezBEQ app is great but the web is pretty much just as good now.
