I just found a link to this new software (on Hacker News):

HIFIScan: https://github.com/erdewit/HiFiScan

From the page:
The goal of HiFiScan is to help equalize an audio system to get the best possible audio quality from it. There are two ways to do this:

1. Manual: The realtime frequency spectrum is displayed and the peaks and troughs can be interactively equalized away.

2. Automatic: The frequency response is measured and a correction is calculated. This correction is a phase-neutral finite impulse response (FIR) that can be imported into most equalizer programs.

The measuring is done by playing a "chirp" sound that sweeps across all frequencies and recording how loud each frequency comes out of the speakers. A good microphone is needed, with a wide frequency range and preferably with a flat frequency response.

The equalization itself is not provided; It can be performed by an equalizer of your choice, such as EasyEffects for Linux, Equalizer APO and Peace for Windows, or eqMac for macOS.

Nice, thanks! Time to invest in a flat USB mic. Any suggestions for a good, inexpensive one?
