I’m trying to implement a notched filter using audacity but first I want to flatten the frequency spectrum of my music. The text I’m following has the following explanation :
In a first processing step, the music energy spectrum was digitally “flattened” by redistributing energy from lower to very high frequency ranges.
To me this means flattening the frequency response using a graphic equaliser. I should be able to do this manually but I want to modify several tracks.
Is there a filter that will do this for me?
Thanks
