Im using the Filter 3 to make the music fade and then turn it back again.
Just automating the cutoff so it will make the effect.
But it sometimes makes a scratchy noise at some point, which I rather would live without.
Have tried to change the inertia, but that didn’t help. Any suggestions on how to avoid that noise?
what type of filter are you using , state variable , moog or butterworth …lp, hp ,bp ??
Resonance cranked up on low pass can cause clipping , but noise ???
Go to automation lane and use line or curve for interpolation
The problem is actually pretty easy to recreate. I’ve ran into it myself a few times in the past.
It’s easiest to hear when listening on headphones and playing a low note with a pure sound like a sine wave. You can hear the noise while adjusting the cutoff frequency. Increasing the inertia makes it a bit better, but still not perfect. The noise comes from interpolating between the filter co-efficient changes. Intepolation is necessary in order to keep the co-efficient recalculations within a reasonable amount of CPU usage, otherwise it would usually be total overkill to do this on a per-sample basis.
It affects each filter type a bit differently, but it’s probably worst on the butterworth types which are better suited to static filtering jobs. The noise becomes pretty much non-existent when using the 24dB Moog filter type with low resonance and a bit of inertia to help smooth things out, so if you want to do rapid modulations with a filter then it’s probably best to use this configuration instead.
It might be some sort of clipping, but still it’s not quite, because it sounds like the sound is breaking through a barrier or something.
Im using the LP, 24 dB 4Pole.
Just found out Im unaware of how to add a URL of my .xrns file :S
EDIT:
Could this have something do to with my speakers?
Do you have the song maximized close to -0db before the filter? Filtering can often increase the apmlitude of the signal, especially with the butterworths. Try adding a maximizer after the filter.
