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

MetaSkew is a granular delay and pitch-shift effect built for producers, musicians, and sound designers who want one processor for width, motion, ambience, and controlled damage. What you can shape: - Delay time from tight doubling to long phrase memory - Pitch from deep drops to shimmer intervals - Grain size, smoothing, and gain for soft clouds or chopped repeats - Feedback, pan, mix, and output for clean blend control - Latch for frozen textures and phrase-end captures - Spread and Skew for stereo width, asymmetry, and unstable character The signature Skew control is the fastest way to move from polished enhancement into unstable texture. Keep it low for subtle smear, or push it with Spread, Feedback, and LFO movement for broken motion. Modulation is built in. Three LFOs can run free or sync to musical divisions, with Sine, Triangle, Sample & Hold, and Saw shapes. Route movement to Delay, Pitch, Grain, Smoothing, Feedback, Mix, Pan, Spread, or Skew, then push subtle drift or obvious rhythmic motion. Presets are designed around real production jobs, not random patches. Browse Utility, Width, Pitch, Atmosphere, Motion, Rhythmic, Freeze, Destruction, and Signature categories. Save your own snapshots, recall them later, and keep user presets synced through iCloud when available. For hands-on control, MIDI Learn lets you map parameters to hardware. Default assignments cover the core effect, and MIDI CC broadcast can reflect parameter movement in connected setups. Use MetaSkew for: - Vocal throws and shimmer trails - Wide synth doubles and guitar halos - Drum stutters, glitch fills, and tempo-locked motion - Frozen pads and transition beds - Experimental resynthesis, smear, and warped ambience MetaSkew includes a standalone app and effect plugin for host apps that support AUv3 plug-ins.

Verdict

The call

The clearest difference is price: Stone Echo at $2.99 against MetaSkew's $14.99. Stone Echo also leads on ratings volume (4 vs 1) and iOS requirement (10.0 vs 17.0). MetaSkew's advantage is rating (5.0 vs 2.8) and update cadence (every 5 weeks vs every 38 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
