I've used Room EQ Wizard to generate impulse response filters. These filters can be loaded into a Digital Signal Processor which will then correct the audio signal according to the speaker and room acoustics.
I'm using these filters with Shairport-Sync on a Raspberry Pi and they work really really well.
I want to also use them with my Mac, but I haven't found a way to do it yet. What I'm hoping for is that there is some piece of software that can read in the audio stream, apply the filter and then output it seamlessly - whether that be some sort of plugin for macOS itself, or whether it means routing audio through a software processor using something like Blackhole .
