Audio Damage Discord4 Now Available For iOS, Mac, PC

Audio Damage has released Discord4, the latest version of their stereo pitch shifting effect.

The pitch-shifter consists of three separate algorithms:

  • a “vintage” mode (the original Discord algorithm, modeled on the Eventide H910 and H949),
  • a “clean” mode for more modern shifting sounds, and
  • a “granular” mode for experimental effects.

Each mode has its strengths, depending on the input material, and Discord3 has a broad palette of capabilities as a result.


  • Pitch Shifting: Discord4 contains a pair of shifters with three separate algorithms (Vintage, Clean, and Granular) for different styles of pitch shifting.
  • Buffer Size Control: The P1 (Vintage) and P2 (Clean) algorithms have a Buffer Size control, from 32 to 2048 samples, for fine-tuning the pitch shifting effect.
  • Delay: Tempo-synced or free-running delays with feedback, cross-feedback, and a sophisticated bandpass filter.
  • Reverb: A simple stereo reverb is added to the feedback path, for “shimmer” effects and further sound exploration.
  • Modulation: Two of our new FLFO (Flexible Low-Frequency Oscillator) with tempo sync and an arbitrary waveform, capable of a nearly infinite number of modulation shapes using only three controls.
  • True Stereo Operation: Discord4 has a true stereo signal path, with entirely independent control over each side, finishing with panorama settings for stereo width.
  • MIDI Note Control: Six octaves of pitch-shifting can be controlled with MIDI note input.
  • All-New GUI: Vector-based resizable user interface.
  • Presets: Cross-platform XML-based preset manager.

Discord4 is available now for US $5.99 for iOS and $59.00 for Mac & Windows.
