Echo effect Audio Unit V3 inspired by the mayan pyramids acoustic echo. I come up with a complex phase modulated frequency of the echo so you can change it’s frequency signature. It is kind of changing the material of the reflective surface and I called it “Stone F”. I have made the echo to sound more music friendly to me but there is button called “UFO” and if you press it the effect is more close to the mayan just shifting the frequency backwards (I liked that better). You can also control the feedback of the phase modulation. The effect can work as a stand alone app and as an audio unit AUV3 plug-in. Stone Echo is an effect that is heavy on the CPU Controls: - Time - time offset of the echo - Stone F - frequency response of the echo - Feedback - echo feedback - Level - the volume of the echo - UFO - heavy modulated echo

- Set delay time in exact samples
- Long delay times (up to 1 second at 48KHz)
- Smoothly toggle between dry and delayed signal
- Displays actual delay time in milliseconds
- AUv3 effects plugin
- Standalone or host compatible

MicroLag is a delay audio processor that allows you to set the delay time in an exact number of samples. While there are already quite a few sample delay plugins available, I couldn’t find one that quite fit my needs, so I made one. MicroLag allows you to set relatively long delay times, e.g. up to around 1 second at 48KHz sampling rate. You can also smoothly toggle between the delayed and bypassed / dry signal. Finally, the actual delay time in milliseconds (depending on the host sample rate) is displayed. That’s basically it! MicroLag is an AUv3 effects plugin that can run standalone, or in any AUv3 compatible host such as Logic Pro, GarageBand or AUM. MicroLag 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 MicroLag on Mac / desktop, please ensure that your favourite DAW / host supports AUv3 (not just AU).

Verdict
The clearest difference is rating: MicroLag at 5.0 against Stone Echo's 2.8. MicroLag also leads on price ($1.99 vs $2.99). Stone Echo's advantage is ratings volume (4 vs 1) and iOS requirement (10.0 vs 13.0). On ads, in-app purchases, monetization model and device support there is nothing between them.
