In terms of the zero crossing is there a way on a Wave Editor where it will automatically finds the zero crossing point?
Also what program would be best for importing a sampled sound and converting it into a wavetable? I'd like to do something similar to the "Sequential Wave" wavetable where it actually says something.
I created a wavetable of the NASA audio for "The Eagle Has Landed" in the Wave Editor program - it's definitely crude... I think that may be overly ambitious for the Pro3 in current state ("The Eagle Has Landed" has 6 syllables with probably around 16 phonemes) I strategically picked each of the 16 steps. You can make it out as you swing through the wavetable with envelope or lfo, but its definitely a sort of "abstract synth rendition".
The issue with doing spoken words is that you've only got 16 single cycle steps to import and interpolate between. If it would be possible to import 32 or 64 single cycle reference points, it would be much easier to pull off these type of complex wave morphing sounds.
Ultimately, you need a minimum of one single cycle reference for each phoneme, and preferably 3-4 reference points to capture the initial transient, fundamental/sustain, and decay/release wave signature. I would say that the "Sequential" sound (3 syllables, ~9 phonemes) is probably the maximum you can pull off with a good rendering.
When I started working on the 707 wavetable kit, I initially tried to capture 16 sounds, but realized that I couldn't get enough data for each to capture their character. So I reduced down to 7 sounds (6 sounds with equal timing, and the hi-hat open with twice the reference points) The end result is a sort of degraded, but sonically interesting wave set that can pull off some cool drum patterns. I think I'll probably do a couple more versions of the 707 wavetable set with just 4 sounds (kick, snare, clap, hh-closed), and maybe one with just two sounds (snare, clap). With fewer sounds in the wavetable, you can capture more temporal details (ie: transient attack, spike, fundamental/sustain, initial decay, fade out) Then when morphing through them, they should sound much more realistic.
@creativespiral are you able to batch export the 16 you want? and how are you making them 1024 in length, I had to load each single cycle individually, and then bounce them individually, ending up with 16, 256 long single cycles, that I then dropped in the sequential web thing and it gave me a semi ok wavetable different from what I started with, an octave high. I think the octave is due to working at 44.1 ... maybe it wasnt an octave, but not the same pitch as the factory waves... Lmk what your workflow is like this this. Thanks everyone and anyone trying out here!
Yeah, the WaveEdit program has the ability to both Import Wav sounds to be chopped up into 64 single cycle steps, and the ability to batch export the 64 individual wav snippets. Once you export them, you have to go to the folder, and select the 16 you want to use, and name them with numeric prefixes. Then you can import to the SequentialWaves.com site.
