Woodulator vs JAX P3 - Pitch Shifter III Usage & Stats
The Woodulator is a delay and pitch shifter inspired by analog bucket brigade delays. It also includes 2 versatile modulators.
Pitch shifting is obtained by increasing or decreasing the clock in the delay line and not by FFT calculations.
- Has 2 pitch shifters which can go up or down according to a harmonic scale or in chorus mode
- Modulator source can be internal LFO or external side chain
- Modulator destination can be pitch frequency, pitch amplitude, delay amplitude, panning, feedback amounts or Moog filter frequencies.
- Modulation of pitch frequency can be up, down or both.
- Delay line color can be set with LP/HP/BP/Moog filter and Saturation level.
- Includes HP and LP filters on the input signal
- Includes Moog filter on pitch out signals.
- Pitch shifters have Reverse mode.
- BPM can be set, tapped or synced by the DAW host.
- LFO Square has slew-rate control. (control at 100% generates triangle waveform)
- LFO’s have convenient beat/bar timing popup.
- Delay and pitch signals can be panned L-R on a stereo bus/track.
- Delay and pitch shifter timing can be synced to the bar or re-synced manually (playing live)
- Stereo diff mode can create wide stereo from mono sources.
- Presets can be stored in iCloud Drive (makes them available on all your devices).
- Presets can be switched with Midi Program Changes.
- Major controls can be set with Midi CC messages.

Our frequency domain approach for pitch shifting will use the “phase vocoder” method, that effectively is an FFT/inverse FFT. The term “vocoder” is somewhat misleading here, because it has nothing to do with a real “vocoder”.
FFT will introduce latency too, but the buffers can be kept relatively small and the input can be shifted by exactly this fixed amount of latency for the final mix internally.
Complex mathematical formulas will be used to extract the frequency components from the signal and their corresponding magnitudes. After the frequency is known, it can be modified in controlled manner, thus making pitch and frequency shifting possible in realtime.
If the frequency was modified across all magnitudes equally, the inverse FFT is applied, leaving the audio with a changed pitch. Like the time domain approach of JAX ESSENTIAL SERIES P2, this will produce “chipmonkeyfication” effects, because all transients and formants will be shifted this way too, proportional with the fundamental frequency.
The frequency domain approach has some side effects too. The audio will be smeared slightly but equally across the entire range. Grainy results are less audible than with the time domain approach. It is not well situated for using with strong transient audio material. Excellent results can be achieved with ambient audio material.
