This is the basic idea, but there are other apps which can make it easier. I prefer using Audio Hijack for the EQ part and sending it to a pass-through device set up in Loopback (which, for this use case, functions the same as BlackHole). Source: 8 months ago

- Audio Hijack (also by Rogue Ameba) so I can record myself, the soundboard, and QuickTime all to individual .aiff files. Source: 11 months ago

Another option that has been around for a long time. https://rogueamoeba.com/audiohijack/. Source: 12 months ago

Definitely doable though might point to Rogue Amoeba re: implementation/execution particularly: SoundSource, Loopback & Audio Hijack. Source: about 1 year ago

Problem solved: https://linearmouse.app/ Approximately the same features as SteerMouse but free. I've voluntarily donated to the dev, though. - Source: Hacker News / 16 days ago

I haven't been using it for this purpose, but Linear Mouse should be able to do the trick: https://linearmouse.app/. - Source: Hacker News / 4 months ago

To add to the mouse/input apps mentioned, I'll add https://github.com/thealpa/SaneSideButtons and https://linearmouse.app/, the "avoid installing steelseriesengine or logi options" stack. Source: 6 months ago
