From a single cycle to a finished table

New to wavetables? How wavetables work is an interactive guide where every figure is playable.

Draw and shape: Pencil, line, curve, and harmonic tools. The curve tool bends a wave, squeezes it into an envelope, or limits it between two curves, with templates and an optional region.
Build whole tables: Start from one frame and sweep brightness, filter, fold, sync, formant, PWM, and more across a 1D table or a 2D grid. Keyframes fill in the frames between them.
Import what you have: Serum and Surge tables open directly. Plain WAVs can be sliced into fixed-size frames, or single cycles can be pulled out of a pitched recording.
Play it in your DAW: WaveStack is also a CLAP, VST3 and AU instrument (CLAP and VST3 on Windows) with the whole editor in the plugin window. Tables are saved with your project, and every sound setting can be automated. About plugin mode
Export for your gear: Pick the synth or device a table is for and Export writes the format, frame size and frame count it expects: Serum, Vital, Surge XT, Ableton, Bitwig, Pigments, the Disting, Deluge, modwave, Iridium and more, or any WAV you like. See every instrument
