I’ve been messing with EQ for hours in Ableton, Garageband, and Audacity. I’m hoping someone can help guide me with smoothing out some harsh / treble-heavy vocals that hurt to listen to right now. Basically I’m looking for a rule of thumb as to which of the high Hz I should cut out, and how far I should cut them, when using the Graphic EQ tool, to get vocals that sound more like something off your everyday pop song.
The trouble with that sample is that is has already been heavily processed. Almost all the low frequencies have been removed, the very high frequencies have been boosted, and a delay has been added.
In a case like this the Plot Spectrum tool is your friend. For comparison, the spectrum of a normal voice and the spectrum of your sample.
You can see that everything below 400 Hz has been heavily cut, and there is a boost above 4000 Hz. So cutting the high frequencies alone won’t help.
Try this as a starting point. You’ll never make it sound like a voice in an everyday pop song, but after this EQ it is somewhat less grating.
