I don't know why NASA TV lets those horrible hums at 1.33KHz and 2.66KHz out into the world, but I just filtered them out on my Mac using iZotope and Audio Hijack. 😬
@donw though now that I see it, I can't enter in 1.33333 or 2.666666, I have to slide a slider that only will do 1.3 or 2.6, which seems not quite parametric
@jsnell Yeah the lack of a distinct notch filter option seems weird to me. That's still how Amazon prevents recording from triggering Alexa isn't it, absence on 9k or something? And surely there's other uses. Let's go, RA!
