Spectral convolution/morphing processor

FFT spectral processor performing live signal convolution or morphing

Novel firmware for the Electrosmith patch.Init() module. (https://modulargrid.net/e/electrosmith-patch-init)

• 1024 bin, 4-hop FFT processor, switchable between convolving (LED on) and morphing (LED off) modes
• convolution is partial, excluding sub-150 Hz frequencies
• signal A/B (switch dependent) dry bass passes to output sum; attenuation under CV control
• dual mono in, stereo out chain
• independent signal A and signal B attenuators (0 to unity)
• A/B input swappable with switch; affects dry bass routing and unvoiced channel tracking
• signal B sample rate under knob and CV control
• parallel non-resonant DJ-style tilt filter on each input; ranges from full attenuation of high frequencies to half attenuation of low frequencies
• Haas-style stereo-spread delay under CV control
• vocoder-esque unvoiced output HF tracking; white noise under CV control summed with main output
• tanh limiter at output
