Studio quality reverb for AUv3 compatible hosts / Audiobus / Inter-app audio and songs from your iTunes music library. AudioReverb is an algorithmic reverberation app which combines the flexibility of vintage algorithmic reverbs with the sonic quality of convolution based reverbs. The creation of high quality reverb needs a realistic simulation of the important early reflections together with a smooth and colorless reverberation tail. The early reflections are the most important clue for the human ear to get a feeling about the dimension and character of a room. Most algorithmic reverbs offer a number of different algorithms to simulate different natural rooms like chamber, halls or artificial ones like plates. AudioReverb uses impulse responses from real acoustic spaces and classical reverb algorithms to emulate their acoustical properties. The resulting reverberation sets new standards in clarity and sense of space ! Use AudioReverb for enhancing your listening experience with your favourite iTunes songs. Use AudioReverb as professional reverb plugin to improve the quality of any Audiobus or Inter-app audio compatible App. • Smooth reverb tail generation. • Early Reflection Modelling. • 118 factory presets. • 4 Band Equalizer. • AudioUnit for AUv3 compatible hosts. • Inter-app audio compatible effect. • Audiobus 3 compatible as effect. • Reverberate any song in your iTunes library. • Low latency live usage with mic and headphones. • Audio recorder. • Audio file export via pasteboard / open in / e-mail
spectwhirl
This audio effect app transforms input sound into new textures and bell-like tones by extracting and manipulating sinewave components. It offers advanced control over delay lines, frequency shifting, and filtering, with gesture recording for parameter automation.
- Sinewave component extraction and grouping
- Delay lines with feedback
- Frequency shifter and sample-and-hold effects
- Configurable filtering
- Gesture recording for automation
- Scene saving and management

"bells and whistles, literally" spectwhirl is a hybrid spectral audio effect. It can extract and rearrange sinewave components from input signal to make new sound textures and bell-like sounds. * input sound is converted to sinewave components that are divided into 4 groups: harmonic, inharmonic, 12-edo and other * each component is fed into a delay line with feedback * there is a group of frequency shifter and sample-and-hold effects before and after delay lines * each set of sinewave components can be filtered * all the parameters can be instantly automated with gesture recording !!! Please note that this effect consumes much CPU and requires a modern device. ====================== Quick Start: Top row of controls enables different parts of user interface: scenes editor ("scene"), controls switch ("edit") and "zoom" controls When "edit" is switch on, you can show or hide various controls (marked as "ctrl") and switch gesture recording automation for some of them (marked with ">") Main control surface displays sonogram with tracked elements. Colors are set accordingly to the group they are assigned (red-orange-green-blue are for harmonic, inharmonic, 12-edo and others). Each "lane" contains delay time controls. * Triangle facing left is for the start locator, it determines initial delay time * Square moves both start and end locators together * When left locator is first moved you can see the right locator with the same triangle. It shows the end of the selected region, the secondary delay time is determined by the difference between left and right locators * if you drag over the area of the region in a lane, the four-dotted/one circle indicator will change its appearance; this changes the arpeggio mode of the region. If set to leftmost position (one circle) the components go in-sync; if set to maximum value (shown as diagonal line with circles) - components are played sequentially * all settings can be stored as "scene" and multiple scenes can be switched sequentially; there is a set of button to move, add and delete scenes. All scenes will be stored as machine state; it can be exported / imported as a single file or as separate file with current scene in the "setup" view The standalone version always starts with output level set to -70 dB to avoid feedback

Verdict
The clearest difference is review sentiment: AudioReverb at 65% against spectwhirl's 33%. AudioReverb also leads on price ($1.99 vs $4.99) and ratings volume (23 vs 5). spectwhirl's advantage is update cadence (every 5 weeks vs every 4 months) and rating (4.0 vs 3.7). On ads, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
AudioReverb costs $1.99 and spectwhirl $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
spectwhirl holds the better App Store score, 4.0 against 3.7. Both are backed by a comparable volume of ratings — 23 and 5 respectively. Written reviews complicate that: 65% of AudioReverb's written reviews are positive against 33% of spectwhirl's, so the app with the better star average is not the one people write more warmly about.
AudioReverb ships an update every 4 months, spectwhirl every 5 weeks. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
