General and best ways to cutoff frequencies?
Posted: Sat Aug 10, 2019 11:51 pm
As the title says. If somebody is willing to offer a schematic, that would be awesome. But I also need a general description (without too much dsp-speek) on how to approach freq cutoff.
What I'm looking for is a stronger, harsher way to suppress specific frequencies, than the normal filtering. Here's are examples:
Say, I want to compress a kick drum. To get a nice strong transient and a full body, I would first completely remove all frequencies below ~30 Hz (the eq I'm using has a simple "cutoff below" button), as they are carrying a lot of energy and make it difficult to compress as strong as would be needed.
Say, I want to better fit vocals in the mix. The vocals are recorded with a rather high frequency spectrum, and unnecessary frequencies are below 500 Hz and above 4 kHz. No matter the band pass settings I use, there always will be frequencies left outside of the band. I'd rather want to completely remove them, to give more room to the other instruments (HH, SH or the like above, bass, low synths and the like below)
So, how to approach this? I assume it has something to do with converting from time to frequency domain and back, or using extremely harsh filters, but that's about all I can understand currently.
