I’m working on a song where I have split up drums into the k/snr/cym layers, but there is an annoyingly loud tamborine on the cymbals layer. I am thinking that I should be able to select exactly the freq range of the tamb, and only whenever that freq is showing activity at a certain level, so I can reduce it there and only there. So for example, anything between 5-7k, and, above -14 dB, only. Possible?
Yes, activate the cymbal layer, then Unmix Levels, set -14dB. This will split the cymbal layer into 2 sub layers based on power, select the highest power layer, then use the frequency range tool to select the 5-7k range, and apply gain reduction.
