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.
