Dynamic Oversampling up to 128x or more
-
thanks guys, I'm working on a distortion emulation, so avoiding aliasing is a must, I want to offer the option of 4x 8x and 16x. I'll just need to figure what's the best filter to use in this case.
Did someone experimented with the filters? The reaper And aliasing seem to be quite good, I wonder what they're using.

I've been playing around with the filterHalfBandFIREquiripple in my hise projects and its really nice. You have to compensate for a but more latency compared to the current oversampling filter but this one is linear phase.
-
@pluginboi That is good to know
My knowledge of the topic stops there. But from what I know about filters, linear phase isn't better than conventional filters, they are just different tools. Since they cause pre-ringing as a result of phase compensation, they are generally bad on fast transient material because of the smoothing they create.I think having a filter selector in the oversample node would be great for selecting the one that better suits the needs.

@Christoph-Hart Do you think adding a selectable oversampling type could be implemented? I'm getting a lot of requests for this and figured I'd hit you before I attempt to hack something together.

@orange How is oversampling useful in ScriptNode if other parts of your plugin do not?

removes aliasing and some intermodulations...
-
@Dan-Korneff if you want I have a source code tweak I can send you for a linear phase oversample mode in script node. I just don't have it built to be switchable between linear and minimum
-
Is there a use case for making this dynamically switchable? Otherwise I could make it a preprocessor that you can set in your extra definitions.
-
@Christoph-Hart For general applications, users are looking for linear phase filters, and for transient material, minimum phase is desirable. Having it be selectable would be super awesome if you're able.

@clevername27 If you use saturation or distortion (in some cases for the convolution too) in the plugin, you have to do oversampling in these parts, otherwise there will be Aliasing.
Apart from this, if there is no saturation or harmonic distortion in the other modules you use, you do not have to oversample; in fact, you should not do it so that you can ensure optimum CPU usage.

@orange Thanks - makes sense.
