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

Gritopia is a character processor built for adding texture, weight, and attitude to any sound. Rather than simply clipping or saturating, Gritopia layers harmonic coloration, evolving instability, and controlled degradation to create rich, expressive character. From subtle warmth to heavily damaged digital grit, every control interacts to produce movement rather than static distortion. The result is an effect that feels alive, constantly shifting as it reshapes your sound. Perfect for drums, bass, synths, guitars, vocals, and creative sound design. Features • Layered saturation and harmonic coloration • Digital erosion and evolving texture • Dynamic instability and motion • Designed for both subtle enhancement and aggressive destruction Controls Grit – Controls the overall amount of texture and saturation. Tone – Shapes the tonal balance of the processed signal. Fuzz – Adds thick harmonic fuzz and aggressive character. Erode – Introduces digital wear, degradation, and broken texture. Drift – Creates slow, evolving movement. Jitter – Adds fast instability and unpredictable variation. Glue – Blends the processed layers into a cohesive sound. Mix – Balances processed and dry signals.
