Spectral tools utilize the PVS phase vocoder in CSound to create a selection of plugins featuring spectral manipulations. These plugins have been tested in Reaper.
Spectral Pedal accumulates FFT frames to create a sustain pedal effect with any sound. This is different from a spectral freeze as new frames are averaged with the previous average.
Cross Synth
Cross Synth allows a user to load several samples and mix between their modulus and phase while also transposing them on a keyboard.
Spectral EQ
Spectral EQ provides an easy to use FFT filter-bank where different filters can be mixed together in real time.
Spectral Delay
Spectral Delay allows a user to delay different FFT bins at different time, amplitudes, and feedbacks. The tables controlling these parameters can be tweened and saved to create dynamic spectral delay effects.
Stereo Cross Synthisis
Stereo Cross Synthesis is a simple plugin that allows users to fade between amplitudes and phase information between audio sources.
