I’m starting with the creation of VST plugins. All is going very well and I’m enjoying it a lot but I have come to a point where I would like to be able to add some EQ to the audio processors I’m creating.
I know there’s a filter DSP which can be used to create hi pass filters, and low pass filters, and band filters. My question is, how could I create a filter that allows me to increase the gain at a random frequency, and with a given Q, as you would do on a parametric EQ? I mean, what would be the right strategy? I’m not looking for code answers here, but more of an understanding of what would be the best way to add a bit of equalization to my own audio processors.
