There's a New Plugin That Uses Wavetables as Spectral Filters — Wavefield by Fine Increments

video upload by Keith Crosley

"Two new uses for wavetables today — and neither is synthesis. First: smallcircles.net/waveforms, a web tool by KRC Mathwaves user Quentin that renders any audio file as stacked ridgeline plots — instant Peter Saville/Joy Division "Unknown Pleasures" album cover art. (Fun fact: the cover visualizes radio pulses from pulsar CP 1919, originally plotted by Harold Craft Jr. for his 1970 Cornell PhD thesis.) Second: Wavefield from Fine Increments, a brand-new spectral filter plugin by Seth Watson that turns wavetable frames into FFT gain curves — three modes (Magnitude, Spectral IR, Phase Warp), tempo sync, stereo spread, and wavetable import. We also drop Wavefield into a Bitwig delay feedback chain for spectral delay, feature Authentic Soundware's new Space Age Colors library, and close with Liminal Space reverb for that Blade Runner/Lexicon 224 vibe. So grab your spectral filter and hold on to your pulsar for this wavetables-a-go-go episode of your favorite talky synthesizer content show!

─── WHAT YOU'LL LEARN ───
What the smallcircles waveform visualizer does and why wavetables are perfect input
How to export your own ridgeline waveform art as SVG for shirts, posters, and album covers
Why Wavefield's spectral filtering sounds different from EQ or conventional filter automation
How Wavefield's three modes (Magnitude, Spectral IR, Phase Warp) differ — and when to use each
How to drive Wavefield with your own wavetables, including KRC Mathwaves
How to put Wavefield inside a Bitwig delay feedback loop for a spectral delay effect
