formant~formant~ performs formant synthesis as described by JP Smets, intended for synthesizing singing-voice components.
sonogram~sonogram~ records an FFT-based sonogram from a loaded sound, allows its frequency-domain data to be modified, and plays the resynthesized result.
tune~tune~ performs real-time tuning of a live monophonic input to desired MIDI pitches while keeping its spectral envelope relatively intact, and can produce polyphonic, spatialized output with independently controlled voices.
audiofreezeaudiofreeze takes an audio signal and, when triggered by its FREEZE control or trigger input, captures a snapshot of the spectral field and recreates it through resynthesis.
fofsynth~fofsynth~ is an alias for fof~ that outputs a signal for formant-style synthesis, with controls for fundamental frequency, formant frequency, rise time, and fall time.
martha~martha~ is a companion to sigmund~ that uses its partial analysis to drive a configurable oscillator bank for resynthesis.
pp.fft-stretch~pp.fft-stretch~ is a stereo phase-vocoder abstraction for time-stretching buffered or recorded audio, with independent playback-speed and transposition controls.
