For the following instrument, I need to change the volume of one harmonic, where its frequency is not static. Please see the image for example. If I wanted to give Number 3 a +6dB boost, I could not be using standard equalizers and filters as the harmonic goes up and down in frequency, and the parameters in these tools are all static.
I cannot set it to be a range either because as the clip plays sometimes as 1 (the fundamental) goes up in frequency, 2 goes into the set range and 3 goes out of this range.
How can I change the volume of a particular harmonic and have the change follow the harmonic itself, regardless of what frequency it fluctuates to?
