Update: I’ve been playing with applying scaled noise reduction (“by”) to different sections of the appended file. Because of the higher frequencies present in the A/C noise, in the end the spectral noise still looks very different in the different sections. So I’m guess a “Noise Reduction To” effect wouldn’t be effective.
I’ve had better luck using spectral gating. But it puts me in a dilemma…
I use spectral gating above 860Hz to reduce the volume (by -18dB) of my breath noises (I don’t want them completely removed because it sounds unnatural).
But to match the noise content with and without A/C noise, I want to hit hard (like by -30dB) between 100Hz and 860Hz, but only gated so as not to wreck my voice.
That puts me back to wishing for a gated band-stop filter. Ho hum…
And I realize this would leave different noise levels behind my voice to with and without A/C noise. I’m not sure if that would matter to ACX.
This all stems from my inability to control the on/off of the outside A/C unit in an adjacent building (I found a sneaky way to turn off the A/C booster fans in my building). So late at night, I’ve been doing narration when the outside unit cycles off – a real PIA.
