Polaris Modes


#1

Hi,

Could someone explain me more precisely the AP (All Pass) mode ?
I understand that it’s useful to add some Q at some frequencies …
What are the differences between the different types ?

Also, what are the differences between A to E types in the N (Notch) mode ?

Thanks for your help :wink:

Hm there used to be a chart with all the frequency and phase responses on the website but it looks like it’s missing in the updated version. I will see if I can dig it up.

Here it is up, I will upload this to the website later.

It doesn’t tell you much about the all-pass filter modes, because there’s no phase response in this graph. The allpass modes differ only in their phase response which you will probably only be able to notice if you blend the allpassed signal back in with a dry signal (this is what the phaser mode does).

Very interesting, thanks :+1:
