EVOC 20 TrackOscillator

Apple

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

EVOC 20 TrackOscillator is a vocoder plugin with a monophonic pitch tracking oscillator that analyzes and transfers the sonic character of an input signal to synthesized sound. It features dual formant filter banks for analysis and synthesis, U/V detection for improved speech intelligibility, and an FM synthesis engine that tracks incoming pitch—making it ideal for classic vocoder effects, pitch-tracking synthesis, and creative filtering applications.

Written from the manual and checked against it. How we check

Key Features

01Monophonic pitch tracking oscillator with FM synthesis engine
02Two formant filter banks with up to 20 frequency bands each
03U/V (Unvoiced/Voiced) detection with Noise, N+Syn, and Blend modes
04Selectable analysis and synthesis input sources: Track, SideChain, or Oscillator
05Formant Stretch and Formant Shift parameters for timbre manipulation
06Three pitch tracking modes: Old (FFT), Cepstrum, and AKF
07LFO with 6 waveforms (Triangle, Sawtooth, Square bipolar, Square unipolar, S&H, Smoothed random) for pitch or formant modulation
08Pitch Quantize with scale/chord selection and automatic pitch correction

Things to Try

  • 01Set Attack to the lowest possible value and Release around 8-10 ms for enhanced articulation on percussive input signals like spoken word or hi-hat
  • 02Use the Freeze button to capture a particular vowel or sustained characteristic of a vocal phrase, then lock it across gaps in the vocal part
  • 03Set Bands to 10-15 as a compromise between sonic precision and resource usage for intelligible speech and vocals
  • 04Combine Formant Shift upward with speech signals to create 'Mickey Mouse' effects by shifting the synthesis filter bank bands up in frequency
