I don’t believe the original video had audio that bad. I think this track is suffering from overprocessing and it’s permanently damaged. Once you get the wineglass effect, it’s hopeless.
Post a bit of the original work, or the track right after splitting. No effects, processing or filters.
There are two roughly similar postings with damaged voice shoots and I had a Twilight Zone moment there.
I think the processing error you posted earlier and the beating I gave it just now are two people trying to get rid of room echoes.
You can’ t get rid of room echoes.
Once you record in a carpet-free room with bare walls (any modern apartment), you’re pretty much dead. Either of us can get rid of the rumble and that whine sound, but the talking in a rain barrel thing is permanent.
Getting good voice recordings in an apartment is harder than you think even if you do get the microphone, mixer, etc, etc right. I’ve been known to use furniture moving pads to kill the wall reflections.
There’s no shortage of people turning their broom closet into a recording studio.
Speaking of that whine sound. Is this a Blue Yeti?
