Apple

Where to get itIncluded with Logic Pro. It is part of that DAW, not a separate download.apple.com

EVOC 20 PolySynth is a vocoder synthesizer plugin that combines a polyphonic synthesizer with vocoding capabilities. It analyzes incoming audio signals and imposes their sonic characteristics onto synthesizer output, enabling classic 'singing robot' effects as well as subtle vocal harmonies and creative sound processing. The plugin features up to 20 analysis and synthesis filter bands for precise sound modeling.

Key Features

01Polyphonic synthesizer with up to 16 voices in Unison/Mono mode
02Up to 20 filter bands in analysis and synthesis filter banks
03Unvoiced/Voiced (U/V) detection for improved speech intelligibility
04Dual and FM synthesis oscillator modes with 50 single-cycle digital waveforms
05Two LFOs with tempo-sync capability for pitch and formant shift modulation
06Formant Shift and Formant Stretch controls for timbral manipulation
07Ensemble effect processor with two chorus modes
08Attack/Release envelope generator and comprehensive filter controls

Things to Try

  • 01Set cutoff as high as possible, then adjust resonance to achieve a brighter high-end signal for better speech intelligibility
  • 02Set Color to full-right position and Level to very low value on the noise generator to achieve a lively and fresh synthesis signal
  • 03Use Release values around 8 to 10 milliseconds as starting points for articulate vocoder sounds
  • 04Compress the analysis signal to improve intelligibility, as level changes reduce vocoder clarity
