I have taken the plunge and ordered a PE Tracker after cancelling my initial preorder last year. That’s besides the point though. I was wondering if people would be interested in sharing single cycle waveforms?

I am collecting links to online resources as I has never created these myself.

@ess made these awesome tools for building your own waveforms: Soft/Hardcore: Single cycle waveform tools

Cool, I saw that. Does this need max? Or have I misunderstood?

If I recall correctly, they’re standalone applications and don’t require Max to be installed. It’s been a while since I’ve used them.

Cool. I’ll need to give it a shot in that case.

AKWF has some oddnesses that made me curious about alternatives.

I ended up finding Galbanum Architecture. Not free, but well done and nicely organized:

Oh wow

I’ve been trying to create a wavetable vector synth in Supercollider but it’s so hard to find the right single-cycle samples with the proper (power of 2) sample length. Total game-changer.

Does this (or any other tool people know about) allow one to import an audio file and edit it to sample length? Also it would ideally automatically adjust the first and last samples to go smoothly to 0, and allow one to stretch/interpolate a sample to a desired length. I’ve tried to do it myself but I don’t have the chops…

Also, one of my fave techniques is to automate/envelope the blend between two different single-cycle waveforms. It gets really interesting when the attack of a brighter waveform decays into a smoother one, you can get some really interesting sounds. Or having a MIDI note trigger a random blend between two timbres…

I found these about a month ago: https://waveeditonline.com/

I was initially excited because they are CC0 and have a huge power-of-2 resolution of 65536 samples. I’ve so far been mostly disappointed by them, as the one’s I’ve tried so far are less waveforms and more just tiny sound samples. Interesting, but they tend to need to be tuned at sub-audio frequencies otherwise they alias like crazy.

allegedly, the galbanum architecture waveforms are used in Massive by NI. I purchased the collection years ago, and hoping to make this year the year to seriously explore and use them. In my experience, these waveforms are not created equally. Some waveform categories are clearly just procedurally generated with a script and are more similar than different. Others seem more crafted and unique. I think I own the 2048-sized sample ones. It’s probably good enough for my needs? But they do have higher-resolution versions which I am almost tempted to purchase. It seems the wavetable size is 2048 and no larger. I purchased the 32-bit floating point version, which is definitely good enough for my needs. For a little bit more, you could purchase a 64-bit precision version of the waveforms.

The AKWF waveforms have been a bit difficult for me to use due to the non-power-of-2 table size of 600. This past year, however, I finally got around to building a more flexible table-lookup oscillator for myself so now that’s not a problem anymore. Some of these waveforms are appropriately named, others are just numbers. Many are variations on classic waveforms (saw, triangle, square, pulse, etc), which I find are hard to appreciate without context within their respective family. There are quite a non-traditional waveforms with here too with unique spectrums, and those have been quite fun to stumble on. 600 is a bit small for wavetable sizes (my goto size is 4096 or 8192), so these will all have a lo-fi chiptune-y quality to them. Considering the AKWF context, this is the idea I think.

The sh-1 waveforms are new to me! Adding them to my collection!

i will re-share this stupid little command line tool for macos/linux

it can do these things to an audio file, which are helpful for waveforms:

  • cut to zero crossings
  • resample to next highest power of 2
  • convert to supercollider format ([pos, delta] pairs)
  • create bandlimited mipmaps for anti-aliased WT synths
