Discord4 vs Degrader
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 Audio Damage stereo pitch shifter, in its fourth generation. Each channel has its own pitch shifter, delay, bandpass filter, and feedback, and every repeat runs back through the shifter, so the same effect can double a vocal, stack fifths into an arpeggio, or send echoes spiraling up or down. Three engines set the character. Vintage is modeled on the H910 and H949 and has their grainy, glitchy character. Modern is cleaner and more transparent. Both have a buffer control from 32 to 2048 samples that changes the character of the shift. Granular cuts the signal into grains from 15 to 100 ms long, with an interval control and a Chaos knob that scrambles them, for anything from soft clouds to complete destruction. Detune the two sides a few cents in opposite directions over a short delay for a wide doubler. Set one side a fifth up, sync the delays, and raise the feedback so each repeat climbs another step. Keep the reverb in the loop for shimmer, then hit Freeze to hold a pad under the part. Turn on MIDI Shift to play harmonies from a keyboard, or ride the pitch wheel for bends. • Three pitch-shift engines: Vintage, Modern, and Granular • True stereo: each side has its own shifter, delay, filter, feedback, and pan, or link them so the right follows the left • Up to three octaves up or down, set by the cent or locked to semitones • Delays up to two seconds per side, free-running or tempo-synced, with feedback and cross-feedback • A bandpass filter in each feedback path, set from an XY pad • A stereo reverb inside the loop, with Freeze to hold the tail indefinitely • Saturation in the loop to keep runaway feedback in check • Two flexible LFOs for pitch, delay time, and filter frequency, shaped by Wave, Skew, and Warp, free from 0.01 to 14 Hz or synced to tempo • MIDI Shift: play the shift amount from a keyboard, with pitch bend, in hosts that send MIDI to effects • A preset browser with folders and favorites, and 50 factory presets from everyday doubling to the thoroughly strange Discord4 runs as an AUv3 plugin inside any compatible iOS host, including AUM, Cubasis, Drambo, and apeMatrix, and as a standalone app with background audio for live input. It is also available for macOS, Windows, and Linux as a desktop plugin. Requires iOS 16 or later. An AUv3 host app is recommended. No subscriptions. No accounts. No nonsense. Buy it once, own it forever.
