AKWF FREE (waveform samples)

All in one pack!

You probably want to download one of the all in one pack. It contains all the single cycle wave forms. The wave format work with many samplers and synths and there are some packages containing samples formatted for ones that need a different format. I choose to sample thes waveforms at D2+2 which equals 600 samples. The biggest reason for that was because I was using Fibonacci sequences to build sounds. As the synths, samplers and computers got better at handling single cycle wave forms it made less sense but I kept the standard of 600 samples anyway.

These waveforms took a great amount of time to sample and I would like to continue this and similar projects, if you want to make that easier for me please please consider to make a small donation.

Wave format (all in one)

This is the original pack and consists of samples that are 600 samples long. This means that the pitch (D2+2) is a bit weird if your sampler / synthesizer isn’t treating the samples a Single Cycle Wave Form.

(samples are suitable for many synthesizers and samplers such as Native Instrument Reaktor, Mutable Instruments Shruti, Image lines Sytrus, Image Line Monomachine, Animoog, Big Tick Rhino, U-he Zebra, Camel Audio Alchemy, Image Line Harmor, Image Line Harmless, Image Line 3xOsc, Elektron Octatrack, Ableton Sampler, Blip Interactive Nanostudio, Single Cell Software Caustic, LittleGPTracker etc.

    Hello, successfully loaded on disting mk4, many thanks for this free package. What do you mean by sampling at d2+2 for 600 samples ? thank you

  • Mire says:

    Thank you for this hard work!
    I formated your waveforms for ZamplerRx if you are interested here is the link

    every folder contains .sfz file for all individual waveforms and .fxb file to load them all together.
    Since limit of zampler patches is 128 some folders (for example AKWF_stereo) have two .fxb files:
    AKWF_stereo_1-128.fxb and AKWF_stereo_129-200.fxb

  • You can never have too many waveforms! Much appreciated.

    First of all, great work!

    I’ve converted these for DUNE 3 wavetables, but can’t seem to add them on GitHub (I am a total noob).

    I tried with GitHub desktop app, and it says I don’t have write access to the repository.

    Do you still accept contributions, and if so, could you please tell me how to go about doing it?


  • Andre says:

    Hi there,

    How do I use these samples, is there a vst or plug-in I can use with them on my OS X, any chance you know?

    Have been reading about waveshaping and made my way here.


  • Daniele says:

    Hey there!

    Thanks for the awesome work. I made a well deserved donation…
    I was browsing the graphs and I think I’ve found a bug in the images:

    The “AKWF_stereo” page has only 3 graphs and then broken file names.

    Greetings from Italy!

  • Tim says:

    These are amazing, thank you, is there a resource anywhere for how to load these in bulk onto an Electribe 2 Sampler? I’m a bit new to this game and all the links I can google are coming up dead.

    Again thanks so much for all your hard work.

    • Glad you like em, hope you get some use out of them. I haven’t got an Electribe but I am sure there are some info some where on the internets. Can’t help you straight of the bat but if you don’t figure it out contact me!

    Thank you a ton! What a sweet sample pack.

  • CRuM says:

    Hi AK

    I got here via youtube loopop channel referring to you for wav forms for synthstrom deluge. I’m pretty new to synth tech etc. Is there a download format you provide above that would better than the all-in-one wav above?

    Thanks for your input and especially for provide the wavs.


    • Hi CRuM!

      Short answer: use the all in one pack!

      I haven’t had the pleasure to work with a deluge but I think the ‘normal’ one “all in one” works as good as the others. The biggest difference is that the ones I did are 600 samples long and most other synths like 256, 512 or 1024 samples long wave forms. The ‘original’ is the best to use as the conversions might affect the sound. You have to transpose / tune the samples and turn down the volume as they peak at 0db they distort on the deluge.

      Instructions for use with Deluge (thanks to Icoustik):

      1. Set one or both oscillators to “sample”
      2. Select any of the waveforms as the sample
      3. Set the sample mode to “Loop”
      4. Transpose the oscillator down 2 semitones and 2 cents, or up 10 semitones
      5. Turn the volume of the oscillator down to about 25 as these waveforms tend to overdrive the amp. This is especially true if they’re used polyphonically.

      Have fun!

  • Austin says:

    Absolutely awesome work man, thank you for sharing! I have used these off and on for some synth jamming for a few years now.

    I did have one question though, how did you incorporate Fibonacci numbers in your synthesis for these samples? Is this something that you would be open to elaborating on? I’ve been fascinated by geometry, proportions, and real numerology in my work for years so I would love to hear some of your methods!

    Thanks. 🙂

    • Hi Austin!

      Just by making a one cycle waveform of anything, it will be full of Fibonacci numbers if you look at the waveform frequency by frequency.

      When I did these I used 600 samples, cause I built my own little synth that can load them in and I did most calculations on samples 600 was really easy. Now I would have probably used 1024 samples but at the time 600 seemed really easy for me to do maths on…

      So my waveform are 600 samples so the math is pretty simple:

      1 cycle – 600 samples long
      2 cycles – 300 samples long (octave)
      3 cycles – 200 samples long
      5 cycles – 120 samples long
      8 cycles – 75 samples long (octave)
      13 – 46,15384615384615 long
      21 – 46,15384615384615 samples long
      etc… (but at a certain point higher frequencies do not sound very musical)

      The synthesizer could “bake” wave forms and then play them at these intervals based on the Fibonacci numbers. So I could make code my basic math and then let the overtones be wave forms already containing wave forms that also consists of a bunch of tones which also display the Fibonacci sequence. Today many synths can do this out of the box but back in the day they could not…

      If you analyse any sound you will see the Fibonacci numbers. Dissonant sounds either changes fast or is actually two sound sources. Musical tones in most cases are not dissonant if you do not count noises as the hammers on a piano might be dissonant to the note you play… I used Fibonacci to be able to make waveform. But if you just cut a sound by a single wave forms and then analyse it the Fibonacci sequence will appear.

      So that I used Fibonacci to create wave forms is true but it would have been impossible to not make them appear (when you analyse the single wave form and look at all the pure sinus tones it is made up by).

      I hope I make a little bit sense… Cool you are using them!

    Thanks for your hard work on this project. Your waveforms have helped me make better music using my paid-for Image-Line Harmor, Image-Line Toxic Biohazard, and Vember Surge. They are all capable of importing waveforms to get more sounds.

    I heavily rely upon getting fresh sounds for musical inspiration and sophistication.
    Thanks for being part of the solution.

  • Scott says:

    Hi Adventure Kid,
    I d/l your waveforms, many of which are included in MuLab, and think they’re fantastic. Thank you for your hard work.

    The reason for my post is to ask how to do this. I know how to edit samples down to a single cycle, what I don’t understand is the tuning of them and if I can use this method on ANY type of sound? I’m specifically trying to edit 838 patches I sampled from my old MC-909, but I find some of these are too ‘random’ to be able to use a single cycle to replicate. Can I use this method or do they need to be longer?

    I’m new to sampling, and can’t seem to find much info on this procedure so any advice would be greatly appreciated.


    • Hi Scott!

      There is some software that makes it easier but for most sounds the best is to locate 8 cycles then xfade it with itself which give you 4 cycles xfade again and you get 2 cycles and xfade again to get 1 cycle.

      For some sounds that just won’t work and then some kind of spectral conversion might be needed. There is some software that can do this that only runs on PC and is inspired by the fairlight. I don’t remember the name. But for the highest quality I would use a modern day spectral synthesizer such as image line’s Harmor. You can load in a sample and set the speed of the reading head to zero. It might need you to xfade 2 cycles into one to get the best sound but it is pretty awesome if it’s a modulating sound where it is hard to find the cycles.

      There will be a different in the sound from a recording to a single cycle waveform but you should be able to get some of the same character at least.

      Happy sampling!

  • Can says:

    Hey Guys,
    quick question because Im quite confused.

    Does a pack of these Sounds exist which are tuned to C that i can play chords with? I ask because i downloaded a tuned-to-C pack and whenever I play a minor chord for example I have the impression thats not quite in tune. I use my Electribe Sampler which can tune start end and loop point for the samples. If this helps
    Thanks alot Can

  • Ian Wilson (Analoguesque Sound Designs) says:

    Hi Kristoffer

    I downloaded your single-cycle waveform set and cannot wait to use it in my Studiologic Sledge 2.0 synth.

    Are the waveforms all generated at the same frequency, and if so, what is it? This would make it easier to tune :).

    The reason I was looking for single-cycle waveforms is because I had created a VB program years ago, for generating 4-Operator FM waveforms that could be used in samplers. It was relatively standard 4-Op FM synthesis, but I had added bit-depth changes, filters, special feedback algorithms … etc, which allowed me to produce a huge sonic palette of sounds. Once I had a sound I liked, the software would generate it at 55Hz, 110Hz, 220Hz, 440Hz, and 880Hz, and with a sustained end where the waveform repeated, making it very easy to loop while keeping the attach of the sound if needed.

    Anyway, I found that I am not able to use my 880Hz waveforms in the Sledge because it requires at least a few hundred samples for the loop to work properly. My 880Hz waveforms loop at about 50 samples (a single cycle). I can’t loop at larger amounts because I had saved the original waveforms with just a little more than a single-cycle wave.

    This is the reason I went searching for a new set of waveforms and was glad to find yours. 🙂


  • SirSickSik says:

    I’ve resampled, sample-length adjusted to 1024 samples, renamed and converted all the waveforms to be usable by the axoloti for a giant wavetable synthesiser. Could I send these to you so they can be shared for the axoloti community forum from your site?
    They’re now called W0000 to W4358, so they can be used as 4 wavetables of 999 samples each and one of 358 samples (would be nice to get that one to 999 too, if you know what I mean…).

    • I used different ones but I like Edison by Image-line as it is so fast when doing these kind of small edits. The problem is that sometimes you have to blend one cycle with the cycles next to it. Edison can do that, so it’s handy. But I think most editors have similar featured. Edison comes with FL Studio and used inside it – it is very fast and easy to do these kind of edits. Good luck!

    Adventure Kid waveforms resampled to C and with octaves spread across slices so each wave file contains C0-C7. Made for Octatrack but adaptable for gear that can set start end end points of samples. Should save space and directory browsing.
