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

Verdict
The clearest difference is rating: Refraktions at 4.5 against Stone Echo's 2.8. Refraktions also leads on review sentiment (90% vs 50%) and update cadence (every 2 months vs every 38 months). Stone Echo's advantage is price ($2.99 vs $5.99) and iOS requirement (10.0 vs 14.3). On ads, in-app purchases, monetization model and device support there is nothing between them.
