Problem to make a perfect "DJ" style filter
Hello,
What I call a "DJ" style filter : 2 filters in series : LP -> HP using only 1 cutoff control.
About the cutoff control :
- From 8:00 to 12:00, I control the cutoff of the LP filter
- From 12:00 to 4:00, I control the cutoff of the HP filter
The way from LP to HP (and from HP to LP) have to be perfectly smooth.
I would like to have the possibility to initialize my controls, Cutoff in particular.
With my current patch, I have 2 problems :
- If I initialize my cutoff control where this one is in the HP field, I have a boost in the final level (I don't have this problem if I initialize my cutoff control when this one is in the LP fied).
- If I move my cutoff control from HP to LP, I have a boost in the final level at 12:00 (I don't have this problem if I move it from LP to HP at 12:00).
I add my patch with comments for a perfect understanding.
Thank you for your help !
Best,
Alex
Your init value for Q is 2.
How should that be linear ?
insert filtergraph~ and watch what happens if Q is set higher than 0.707
Hello
Thank you for helping me.
Unfortunately, setting the Q at 0.707 doesn't remove this problem.
I don't see anything wrong in the Spectroscope object.
You need to smooth init to ramp from current to init value. not jump.
Both filters behave the same, but jumping from hipass filter to "neutral" (no way with that filter)
causes more thump at output.
I did it but it doesn't work (with different ramp time).
I don't know what you tried..
Something like this ?
that filter is anyway not really usefull in my ears
Something like that effectively...
This cutoff control si very handy during live performance !
If it serves you well, than all ok.
But HiPass set at anything higher than 10 KHz is close to mute.
Maybe that's why you name it DJ style filter.
For sure.
Thank you
