Discord4 vs BLEASS Chorus
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Discord4
This stereo pitch-shifting delay app offers three distinct algorithms for vintage, clean, or experimental granular effects. It features tempo-synced delays, a reverb in the feedback loop, and flexible LFO modulation for extensive sound design. Control pitch shifts with MIDI and fine-tune effects with buffer size adjustments.
- Three pitch-shifting algorithms (Vintage, Clean, Granular)
- Tempo-synced and free-running delays
- Reverb in feedback loop for shimmer effects
- Flexible LFO modulation
- MIDI note control for pitch shifting
- True stereo operation with panorama controls
- Resizable vector-based GUI

Discord4 is the latest version of our most popular and long-lived product, our Discord stereo pitch shifter. Originally modeled from the H910, Discord has long since become its own effect and a studio standby, and this version includes major additions to further stretch its capabilities. This application includes a stand-alone version (with Inter-App Audio) and an AUv3 effect for use in hosts that support that format, such as Beatmaker 3, AUM, Cubasis, and Garageband. A full PDF manual is available at the Audio Damage website. Discord4 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. The P1 and P2 algorithms have full control over the buffer (window) size of the shift effect, for fine tuning the shift to the input signal, or for stranger sound effects. At the extremes of the six-octave shift range, some truly strange aliasing and artifacts can be had with this control. Discord4 retains its pair of tempo-synced delays and bandpass filters from previous versions, and adds a reverb in the feedback loop (for easy access to "shimmer" effects). We have also replaced the modulation sources from the original with our all-new FLFO (Flexible LFO) design. Panorama controls are included to control the stereo width of the wet signal. Finally, soft saturation and limiting have been added or improved throughout the signal path, for an overall improved sound and added vintage-style warmth, and to allow for extreme feedback experiments without fear of overloading your DAW's channel. Features • 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.

With up to four fully stereo chorus voices, BLEASS Chorus can create everything from subtle movement and gentle thickening to rich, complex modulations, while offering precise control over stereo width, prominence and intensity. In high-pass mode, the input filter is perfect for bringing out the space and airiness within a sound, before the advanced modulation engine makes that airiness shimmer and dance. Switching the filter to shelving mode opens up a whole new range of possibilities, from deliciously warm thickening effects to sparser, thinned-out lo-fi modulations. The detailed and colourful oscilloscope at the centre of the BLEASS Chorus interface shows you at a glance exactly what the plugin is doing. Thanks to the super-efficient BLEASS processing engine, this helpful visualisation won’t come at the expense of your system’s resources. More information and technical specifications available on https://www.bleass.com/chorus/ BLEASS Chorus can be launched as an AUv3 plugin or as a standalone app. BLEASS Chorus is also available for Windows and macOS.
