I am trying to clean up a live recording, and have a couple of questions. What frequency do I need to cut to get rid of a boomy bass drum? On one of the tracks, the bass is too loud. What is the best frequency to cut to deemphasize bass guitar? On a couple of tracks, the female vocalist is too quiet. What is the best frequency to tweak to bring out her voice? Is there any decent, freeware recording program that has a 2/3, 1/2, or 1/3 octave equalizer? Thanks!
