At 44:43 - 45:13, Ray mentioned something interesting:
I filtered the annoying background noise from Dr. Ray Peat's radio interview, essentially harmonics of 120 Hz up into the 3 kHz range, in Adobe Audition.
Enjoy!
I don't think it's simple notch bands, that would create pretty poor, phasey sounding audio. Most likely spectral editing in Audition.Thanks Stephan. Sounds much better. And now if I may look a gift horse in the mouth ... the only issue is that the overall level is much lower. I used wavepad to "normalize" the clip so that the peaks are at max level. It's a one-click solution on WavePad. Never tried Adobe, so I don't know if there's a similar feature.
Also, I'm curious ... what EQ settings did you use to remove the hum? Is this multiple super-narrow-band dips of 120Hz and octaves above (i.e. 240Hz, 480Hz, etc)?
The simplest was a 1/120 s delay to a phase inverted copy of the audio and then sum them up (a 'comb filter'). All the 120 Hz signals disappeared but then, of course, I got an 8.33 ms echo! So I used about 30 notch filters to get into the 3 kHz range, that did it. I should have checked the sound level though...I don't think it's simple notch bands, that would create pretty poor, phasey sounding audio. Most likely spectral editing in Audition.

Man, that's amazing. I'm in the stone age with my parametric EQ. Thanks for posting it up here!!!!
But you used the spectral editor, yes?The simplest was a 1/120 s delay to a phase inverted copy of the audio and then sum them up (a 'comb filter').

So here is the normalized volume level audio file!
My request is a version without Andrew. He is annoying and bloviates.
Ha ha. And no more hippie wooden flutes while you're at it.
