Hello,
In one project, I am solving a problem with signal interpolation. I have a few things in reserve (Lanczos interpolation), but I would like a solution that uses the Smooth function in the sample editor. What kind of interpolation algorithm does it use?
I have some problems connecting the samples to each other ideally.
So I used Lanczos interpolation.
The result looks much better but it’s still audible somewhere
I’ll probably have to focus more on editing the FM code.
Thanks, just exercising my brain.
I think that these transitions must be solved directly in the creation.
No matter what transition I use, it’s always more or less audible
Yes, the transitions will stay audible, no matter what you do. You could try to lowpass filter the sound to lessen it, but this will ofc create some phase shift and lead to weaker high frequencies in the sound.
2 thoughts on this. The problem seems to happen when you generate different sine segments each starting with a new phase for the sine oscillator
When creating the sound - just remember the phase, letting the oscillator run while it is silent, and then only change the frequency per sample, or the amplitude with a ramp.
Another option, if the segments need to be generated in the original phase setup, is to crossfade the segments over a range of a few samples
I tried some crossfade.
So far only linear transitions, but it looks better.
I don’t know why I didn’t think of it and I immediately wanted to reach for FM demodulation
