blepfx has released Spectra, a $25 plugin that blends two audio sources by reshaping their spectral makeup. Instead of treating each signal as one block, the processor separates broad spectral envelopes from finer harmonic detail, then lets those pieces cross between the main input and sidechain for fresh timbres.
Four processing engines handle the job differently. Linear uses FFT techniques, Hilbert cuts back pre-ringing, LPC brings a rougher speech-coding flavor, and IIR works through narrow filters with zero latency. Each route gives the morphing process a different character.
A four-octave formant control sits beside tilt filtering, envelope freezing, smoothing, and smearing tools. Spectra runs as VST3, AU, or CLAP across macOS, Windows, and Linux.
