About Osci Zero
Free, royalty-free wavetables for Serum, Vital and other wavetable synths. Every file is generated by our own synthesis and simulation engines, then tagged, described and checked before it goes online.
What you get
- WAV files with 256 frames of 2048 samples (32-bit float, mono), the standard Serum wavetable format.
- A 3D/2D preview and a ▶ button on every card: listen before you download. The Sound panel sets the note and whether playback scans through all frames or stays on the selected one.
- Filters by category, tag and use (bass, pad, lead…), search, and sorting by brightness, motion and more.
License in short
Use and modify the wavetables in your music, sound design, videos and games, commercial or not, with no fees and no attribution. You may also use them inside synth presets and sell those presets. You may not resell or share the WAV files themselves or put them into sample or wavetable packs. Read the full license.
How to load a wavetable
- Serum
- Drag the WAV onto the oscillator's wavetable display. To keep it in Serum's browser, copy it into the Tables folder inside Serum's presets folder (menu → Show Serum Presets Folder).
- Vital
- Drag the WAV onto an oscillator's wavetable display.
- Phase Plant
- Drag the WAV onto a Wavetable generator.
- Other synths
- Most synths that import Serum-format wavetables (2048 samples per frame) load these files the same way; check your synth's manual for its import option.
Categories
Each wavetable has one category, like a folder in Serum's browser. The first rule that matches wins.
- Noise
- Flat, noise-like spectrum.
- Vowel
- Built around vocal formants: “a”, “e”, “o” and other vowel colours.
- Digital
- Stepped, glitchy or chaotic, or both harsh and complex.
- Analog
- Close to a classic shape (sine, triangle, saw, square, pulse), or simple and warm.
- Spectral
- Everything else: rich, evolving spectra.
Tags
Tags are measured from the sound itself (character, shape, motion) or come from how the table was made (synthesis, source). Selecting several tags shows files that have all of them.
- dark / bright
- Energy sits in the low or the high harmonics.
- warm / harsh
- Upper harmonics fall off quickly (soft) or stay strong (edgy).
- simple / complex
- Smooth waveform with few wiggles, or a busy, detailed one.
- clean / noisy
- Clear harmonics, or a flat, noise-like spectrum.
- hollow
- Mostly odd harmonics, like a square wave or a clarinet.
- sub / thin
- Strong fundamental (solid low end), or almost none.
- sine, triangle, saw, square, pulse
- Large parts of the table sound like that classic waveform.
- static / evolving
- Little change across frames, or a clear timbre change when you sweep the position.
- opens / closes
- Gets brighter or darker from the first frame to the last, like a filter sweep.
- chaotic
- Neighbouring frames differ a lot: jumpy, unstable movement.
- glitchy
- Mostly smooth, with a few sudden jumps.
- quantized
- Bit-crushed or stepped, with audible digital stairs.
- additive, FM/PM, AM/RM, PWM, spectral, subtractive, digital
- The kind of synthesis used to make the table.
- voice, formant, chimes, bell, organ
- What the table imitates.
Good for and Sound
Good for (bass, sub-bass, lead, pad, pluck, keys, fx, texture, drone) and the Sound words on each file page come from an AI model that listens to the table and looks at its 3D view. They are suggestions, not rules.
Sorting scales
Every file has eight measurements from 0 to 1, shown as bars on its page and available in Sort:
- brightness
- Where the energy sits, from low to high harmonics.
- harshness
- How strong the upper harmonics are compared with the lower ones.
- complexity
- How busy the waveform is.
- noisiness
- How close the spectrum is to noise.
- hollowness
- How much odd harmonics dominate.
- fundamental
- How much energy is in the fundamental (low end).
- motion
- How much the timbre changes across the table.
- jitter
- How much neighbouring frames differ.
