DelayScaper vs EchoSketch
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
DelayScaper
This audio effects plugin offers dual dynamic stereo delays that respond to input intensity and note spacing. It allows for experimental sound design, atmospheric textures, and even looping, with bonus effects like octave pitch-shifting and random reversing.
- Dual stereo delay modules
- Dynamic parameter response to audio input
- Host tempo syncable delay times
- Max 8-second delay time
- Octave Grains effect
- Random Reverse effect
- Envelope followers for modulation

DelayScaper is an AUv3 effects plugin that can run standalone, or in any AUv3 compatible host such as Logic Pro, GarageBand or AUM. DelayScaper currently runs on iOS (iPad & iPhone) and macOS (Intel & Silicon) and is available as a Universal Purchase from the Apple App Store. Overview DelayScaper is a dual dynamic delay effect designed to produce inspiring, and sometimes very unpredictable results that literally responds dynamically to audio input. Playing an instrument through DelayScaper can be especially rewarding when you adjust your playing to what you’re hearing, because DelayScaper can be configured to constantly modify its parameters according to the intensity and spacing of your notes. It’s like having five extra pairs of hands twiddling knobs for you! At its core, DelayScaper comprises two identical stereo delay modules that can run in series or parallel. While it can cover “normal” delay duties, including host tempo syncable delay times, DelayScaper is really for those who like to experiment with sound, especially in the atmospheric and ambient realm. With a maximum delay time of 8 seconds, you can even use DelayScaper as an old-school “free looper” for “Frippertronics” type evolving soundscapes. DelayScaper also features two bonus “one knob FX” effects that are both original designs that complement the core delay processing: “Octave Grains” is a randomised and delayed pitch-shifting algorithm that sits somewhere between a pitch-shifted delay and granular shimmer effect. “Random Reverse” does what you might expect it to do, but often in an unexpected way! Both algorithms will grab random sections of the incoming audio, process it, then feed those into the main delay processing. The dynamics section is where DelayScaper comes to life, and includes dedicated envelope followers for both delays, which can then be used as a modulation source for up to 5 delay parameters for each delay. For example, you can modulate the mix level to create a “ducking delay”, or modulate tone so the delay repeats get brighter or darker depending on how hard or softly you play. A “cascade” feature sends the output of the first delay into the second, allowing you to fine-tune the balance between parallel and series mode.

EchoSketch turns delay and reverb into a live, playable instrument. Shape your sound in real time using a responsive X/Y performance surface designed for intuitive touch expression. At its core are four great-sounding delays: digital, analog, ping-pong, and reverse. The range for each parameter and the XY axes direction can be set independently, allowing you to easily morph between sounds. It works as an Audio Unit plugin or standalone — iOS or Mac. Comprehensive Delays • Digital (patterned after a legendary '80s rack delay), Analog (warm, with tape-style pitch glide), Reverse, and Left/Right Ping-Pong • Delay times can sync to tempo or be set in milliseconds • Feedback features delay-dependent tone shaping — bright for short delays and darker for long ones Convolution Reverb • Stereo or mono Spring, Plate, and Hall • Reverb path is separate from the delay (same as vintage tape echo units), so repeats don’t get washed out Modulation and Filter • Analog-style modulation for chorused, warbly pitch echoes • Tone control — darken or brighten delays, with a center detent for flat Designed for Hands-On Performance • HOLD / LIFT — leave the XY cursor in place, or touch the pad for momentary delay sounds • FREEZE — set the current feedback into an infinite loop and play over it • MOTION — record a gesture on the XY pad and loop it Presets and More • Presets are transferable between hosts • Two looks — light "Trail" and dark "Glow" • Works standalone with live audio or as an AUv3 plugin • Universal — iPad/iPhone also gets you the Mac version — one purchase • Mac: after installing, open EchoSketch once to use it as a plugin in your DAW • Works in AUM, AudioBus, GarageBand, Logic, and other AUv3 hosts
