I built a free browser-based wavetable generator - exports standard .wav

[fineincrements]

Hey all,

I built a free algorithm-based wavetable generator that runs entirely in the browser, and figured this forum would be the right place to share it.

The idea: a timeline of segments, each running one of a set of algorithms, with a morph parameter that evolves across the segment. Drag the dividers to set how much of the table each segment occupies, adjust parameters and layer modifiers on top (reverse/ping-pong, depth scaling, phase shift/animation, invert, mirror), and audition the whole thing in a 3D frame-stack view with a per-frame waveform and harmonic spectrum readout.

A second keyframe-based mode lets you drop in single cycle wavetables, or select frames from larger .wav files to stitch together or interpolate through. There's a play button if you want to hear the current frame or a swept playback at a chosen note before exporting.

Output is a standard .wav file with configurable frame count, frame size, and metadata so it drops cleanly into Serum, Vital, Pigments, Massive, or anything else that imports wavetables.

Upfront disclosure: there's an email gate on the page. Enter an email and you get the tool - no need to subscribe if you don't want, no payment, no account, no limits on exports.

One usage note: Turn off pop-up blockers - some of the controls open pop-ups.

For context on where this came from: I make a plugin called Wavefield (a wavetable-based spectral filter that sweeps through wavetable frames to shape a filter response on incoming audio rather than using the table as an oscillator). The generator was created as a companion utility for designing tables that move musically through Wavefield's processing, and a lot of the algorithms and modifiers are shaped by what creates interesting spectral motion in that context. But standard .wav out means it works anywhere wavetables work, and the algorithms and modifiers are genuinely unique and useful for synth-oscillator wavetables too.

Happy to answer questions about how any of the parameters work, or take feedback and feature requests.

Cheers,
Seth
