I started reading about filters and have a basic understanding but i heard the term "Q" (also seen in the VST "fruity free filter")and didnt know what it was >.> What is it?
Thanks fer yer help~
When working with highpass or lowpass filters, Q boosts the Cutoff Frequency. To see what I mean, turn it all the way up and move the Cutoff Frequency up and down, and you'll hear the various frequencies shriek and distort as the cutoff filter becomes closer and closer to them. Be careful though, turning Q all the way down on the Free Filter actually cuts the Cutoff Frequency a little bit, so to leave it with no effect, set it at one bar in the Fruity Free Filter display.
When working with anything else, Q defines bandwidth, which is how wide of an area the filter affects. For high/low shelves, it basically determines how quickly the gain volume, which you've set, is reached - turn it all the way down, and it happens more slowly, turn it all the way up, and it's reached very quickly. For notch/band passes and a peaking gain, it indirectly determines the number of frequencies it affects - all the way up, very few, all the way down, many.
Hope that helps. :)
