Ho wow, the sample video shows incredible results, I'd love to read more about how to configure it with my own laptop and microphone. Settings ought to be different for each laptop model, right ?

FYI, when attempting to apply this to speakers, the anechoic frequency response is required. If you try to equalize for flat-in-room response, the results are terrible. See this video[1] for loads more information and context.

Huh, I didn't realize pipewire had builtin support for this! I've been using a different piece of software called Easy Effects[1] on my framework laptop.

To equalize my laptop, I ended up buying a umik-1, and using REW to calculate all the filter coefficients (you can import REW's filter export right into Easy Effects). It's a subtle difference at first, but it's much cleaner (I also usually have a compressor and loudness effect enabled, as the framework speakers are pretty quiet).

I couldn't find any mentions of what audio codec it uses in an initial search, but I see "HD Audio" and other sources online say it's a Realtek, so this seems to be a standard Intel HD Audio codec. What's lesser-known is that most if not all of them have a built-in EQ function which can be used to accomplish this (and perhaps the original vendor's Windows drivers already do), but it's not well-documented. Linux has some code for that too (search for EQ in here):

On an old MBP I have a similar setup with these two tools:

- https://ju-x.com/hostingau.html

- https://existential.audio/blackhole/

Default output for applications is set to BlackHole's virtual sound device which the "Ext-In / Track D" channel can pick up in Hosting AU as an input. An "AUDynamicsProcessor" and "AUGraphicEQ" stage later (both built-in macOS units) it is sent back to the real output device.
