WAIL - Industrial Feedback Synthesiser, Drone and AUV3 FX Turn unstable feedback into a playable instrument. WAIL forces a self-resonating signal into submission, generating harsh drones, soaring screams, and aggressive textures that traditional synths refuse to touch. Built for zero menu-diving and pure performance, WAIL delivers raw, uncompromised noise control in a single intuitive screen. TAME THE NOISE: 4 Dynamic XY Pads: Instant tactile control over Feedback/Filter, Bite/Space, Ring/Fold, and Comb/Sub. Dedicated Performance Knobs: Master, Spread, Grind, and Tune, with dual-axis Coarse/Fine tuning designed for precise, subtle adjustments mid-performance. Real-Time Visuals: Built-in integrated oscilloscope displays waveform stability and feedback saturation as you play. Drone or MIDI Triggered: Play as an evolving drone, or connect a MIDI keyboard or sequencer. AUv3 FX: Load WAIL as an effect in your host and run any track through its feedback engine. Push a drum loop, a vocal, or a synth line into full self-resonating collapse, or layer WAIL's own drone on top of what you send in. Seamless AUv3 Integration: Full host transport sync, preset save/recall, and universal MIDI CC learn across all 12 parameters. Universal Support: Formatted natively for both iPad and iPhone as an AUv3 plugin or Standalone app. 12 parameters. 4 XY pads. One feedback loop trying to escape.

AuTranspose
This utility plugin allows for simple pitch-shifting and detuning of audio. It offers a range of +/- one octave in semitones and +/- 100 cents detune. Note that it introduces audio latency, making it unsuitable for real-time performance where timing is critical.
- Pitch shifting +/- one octave
- Detune +/- 100 cents
- AUv3 effects plugin
- Standalone or host compatible
- Latency reporting on UI
- Simple and easy to use

AuTranspose is a simple pitch-shifting / transpose utility plugin with a range of +/- one octave in semitones, and a +/- 100 cents detune (semitone up or down). Please note that AuTranspose has audio latency (see the PLEASE READ section below) so it is not really suitable for realtime pitch shifting in situations where timing is critical - for example, shifting the pitch of an instrument as you play it or syncing multiple tracks in a live performance. AuTranspose is an AUv3 effects plugin that can run standalone, or in any AUv3 compatible host such as Logic Pro, GarageBand or AUM. AuTranspose currently runs on iPadOS / iOS (iPad & iPhone) and macOS (Intel & Silicon) and is available as a Universal Purchase from the Apple App Store. If you’re planning on using AuTranspose on Mac / desktop, please ensure that your favourite DAW / host supports AUv3 (not just AU). PLEASE READ THIS SECTION CAREFULLY! AuTranspose uses a pitch shifting technique that adds latency (delay) to the processed audio. Please note that this is unrelated to your audio interface buffer size or sample rate. The quality of the pitch conversion is a compromise between low latency or decent quality results - unfortunately, you can’t have both. AuTranspose can get as low as around 25ms latency which is just about good enough for a guitar octaver type application, but will probably sound a bit “wobbly” / “lo-fi” on more general audio. If you’re interested in a more guitar-centric octaver, please check out OttavaBassa which uses similar DSP, but tuned for guitar. AuTranspose does not report its latency to the host! This is by design. Instead, the current latency is shown on the UI in samples (and ms) so you can decide yourself if you need to compensate for it - for example, when remixing projects and you need to re-sync tracks that aren’t going through AuTranspose. So what is it for, and why did I make it? In my own search for a simple pitch shifter, I found that the really simple ones didn’t sound so good, and the ones that did produce good results were fairly complicated and / or CPU intensive. So I tried to make something that was very simple to use, that produced reasonable results. When might AuTranspose be useful? Backing tracks: You might want to transpose up or down by a semitone or two to put the song in a more comfortable key to sing, or perhaps you tune your guitar to Eb. In these situations, you could probably transpose the whole track up or down and it’ll still sound OK. The only other thing to keep in mind is that the playback of the track will be delayed by the latency so as long as the backing track doesn’t have to sync with anything else, you should be fine. Remixing recorded projects: Perhaps you have a project that’s audio only and you’ve decided it needs to be in a different key. You could use AuTranspose to pitch-shift the tracks or stems that need to be in key, but leave the percussion tracks as they are. You can then add a sample length delay (*) to these tracks so that everything plays in sync. For convenience AuTranspose reports the number of samples to adjust by. And of course, you could simply use AuTranspose as an effect in itself, for example as a “Lo-Fi” pitch shifter for a retro vibe. There are a few examples in the factory presets to get you started. (*) In cases where you need to compensate for latency on tracks that aren’t using AuTranspose, add a sample delay plugin to those tracks and set the number of samples to what’s reported on the AuTranspose UI. There are several sample delay plugins available, although many of the free ones (Apple’s included) don’t go that high. By the time you read this, MicroLag should be available which supports longer delay times.

Verdict
The clearest difference is price: AuTranspose at $2.99 against WAIL's $9.99. AuTranspose also leads on review sentiment (100% vs 83%) and iOS requirement (13.0 vs 15.6). WAIL's advantage is ratings volume (8 vs 1). On rating, ads, in-app purchases and monetization model there is nothing between them.

WAIL costs $9.99 and AuTranspose $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 5.0 for WAIL against 5.0 for AuTranspose. That said, the two scores are not equally well evidenced: WAIL has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 83% of WAIL's written reviews are positive against 100% of AuTranspose's.
