the t.racks DSP 4x4 Mini

I say it straight away, I have used more DSPs in my career than I drank coffees and anything under hundreds of euros would have been a laugh in those days. But wanted something on a budget for the project studio, ran across this thing and I'm honestly surprised.

It's not perfect. The eg is soft and not particularly precise. The delays only come in steps of fractions of a millisecond and the software UI looks like, well, a typical German app from the 90s.

But none of that matters for this price! It was good enough to match up against measurements using SMAART and the result is pretty pleasant. The sound is on par with much more expensive units and it's versatile enough to deal with a typical stereo + sub woofer situation. Not sure I would recommend it for an surround sound work since the delay is simply not precise enough for properly tuning multiple sources to cinema level but for the home studio it's simply ground breaking.

Only one gripe I have is the software. It's really 90s blocky cheap windows stuff. These days things such as being able to increment values via mouse scroll, proper save dialogs or even being able to sync two channels together is almost standard. As both a programmer and audio engineer I think that it's pure laziness and lack of vision making software this old school these days. Fix that and this unit could become world famous and not just some obscure German home brand!
