SPC Tuner
Bend any sound into a new pitch world — smoothly.
“Hear the hidden tuning of any sound — then move it into another pitch universe.”
SPC Tuner is a phase-aware spectral retuner delivered as a CLAP plugin. It analyses the incoming sound, works out its true pitch reference, and smoothly bends the whole spectral body toward the tuning world you pick — the tone, transients and stereo image staying intact. A scale-aware correction layer can pull notes onto the key of your song, and A=440 doubles as a repair mode that restores drifted audio to standard pitch while leaving already-in-tune material alone. Two modes cover playing (Live, low latency) and finished clips (Baked, a stable tuning map over the whole clip). The ultraviolet cosmic interface shows it all: twin orbs for detected vs corrected pitch, a cymatic spectral field of dry versus changed, and colours that intensify the more the sound is transformed.
Available now — a one-time purchase, yours to keep.

Latest updates
Actively developed — recent fixes and improvements:
- Housekeeping patch — loading a project now reliably refreshes the on-screen controls, typing a target/theme by name matches exactly, and state round-trips cleanly in every host. No sound change; projects and activation carry over.
- Theme Pack — 11 new console themes (click the THEME chip): Dark, Cyberpunk, Candy, Spectrum, Black & Gold, Lapis Lazuli, Pink, Sand, Retro, Game Boy and Shadow Purple, alongside the originals.
- Initial release — 25 tuning worlds, automatic source detection, Live & Baked modes

Made to be played
Every knob morphs the sound.
SPC Tuner is built for real-time sound design. Turn a control and the whole signal reacts at once — spectral colour, granular texture and modulation respond live, right in your DAW. Nothing is baked in: every parameter is fully automatable and MIDI-mappable, so you can draw evolving movement, morph a vector-scope signal, and lock in a one-of-a-kind sound no preset could give you.
