Wavetable Creation in 2025 - Can't get interpolation...
-
How are we doing this now?! I've got a few single cycle .wav files into a sampler, velocity stacked them like we used to for Wavetables, then opened the (new?) Wavetable Creator window, selected the correct sample map and exported it to .hwt in resample mode.
The Wavetable is created and works in the WT synth, however it just uses the first table. If I move the index there don't seem to be any other tables, and no others in the visualiser either....

@Morphoice did you make some Wavetables recently?
-
@DanH no, I completely gave up on that when I discovered faust

don't use the velocity stacking (I think I've removed those). If you don't need to resample acousting material and already have power of two sized wavetables, just load in a sample that has all the wavetables stitched together, and use the resample mode. Ideally you can pass in the cycle length so the chances of the algorithm messing that up is smaller.

@Christoph-Hart Ah ok, thanks! So far so good. However, how do I enter the amount of cycles? I'm using only 6/7 but, if I am reading this right, the minimum amount I can tell it is 128?
-
@DanH no it figures it out using advanced AI technology:
numWavetables = fileLength / cycleLength.
-
@Christoph-Hart Ok - I tried one with 27 cycles... Didn't like it. What's the limit more or less?
And any plans to get an angled view of the wavetables for general UI sexiness?

Heya, can someone help me sanity check something?
I grabbed some single cycle wavetables from:
https://www.adventurekid.se/akrt/waveforms/adventure-kid-waveforms/They come as individual wav files, that are 44.1kHz sample-rate, and are 600 samples long.
The sine wave one I've picked has 12 files. Meaning a total length of 7200.
I've stitched them together in Reaper, and I have confirmed that the file is indeed 7200 samples long.
I've then dragged that into a sampler, created a sample map where the file spans the entire keyboard, but there are no velocity layers. I've set the root note to D1 as specified in the readme for the samples.
When I try to use this file/sample map with the Wavetable creator, the resample mode does not work.
I am assuming this is because the individual wavetables are 600 samples long, and thus not a power of 2 number.
I can use one of the other analysis modes, but since it has 12 files I get a kind of FFT spectral noise-burst at the end of the file when I select a slice amount that is higher than my file amount. I assume that means I should not use 12 files, and I should crop my file selection to 8, or even duplicate the first few files to hit 16??
Typically speaking, what are the most ideal specs for wavetable files in order to make this process as smooth as possible??? I would assume that the resample analysis mode is the cleanest ??

@Orvillain a cycle should be 2048 samples long. The total needs to be a multiple of that.
