And you don't need a recording studio to enable it on more hardware. marcan did the measurements for the MacBooks with a cheap measurement mic.
So you can have great audio on any hardware by just doing the measurements and including them in the asahi-audio package, _in upstream fedora_.

EDIT: Also, about recording IRS: both the mic and the room environment impact the response data. Using cheap mic in your room does introduce distortion.
However, I realized I was kinda making an assumption that IRS was being recorded for effects. If you're just flattening the response curve, they should work mostly fine. This can become an issue if it's used for effects (e.g. mimicking 2ch Dolby Atmos) because the distortion can be amplified by the environment.
Also, in the long term, using a standardized setup helps with maintaining the quality of IRS. You really want to be able to reproduce the setup, so that you can further improve the data. It's better than subjectively keep fiddling with EQ sliders.
