EQ Bandwidth

Apr 5 at 10:07 AM
I was wondering what 0.8f for bandwidth, used in the examples, relates to? 80% of what? How wide is a 100% bandwidth? (I assume it is a percentage)

Also, is there a way to set the actual Q, Q and bandwidth being two different things. Q would be the shape of the bandwidth bell curve. A way, perhaps, to set it from thin to fat?

Love NAudio, using it in this project:

Q is the parameter for the width of the frequency filter. The higher, the more frequencies around are affected, the lower less frequencies or even just the selected frequency are affected.

This video explains that quite well without the maths: https://www.youtube.com/watch?v=hNVdvsOEF7w
