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

Recodec is an AUv3 audio effect for turning clean signal into textured, character-rich tone. Use Crusher for bit-depth style reduction, Reducer for sample-rate style degradation, Refine for smoother oversampled processing, Drive for added harmonic color, and Bass and Treble to rebalance the result. Then place the effect exactly where it belongs with Dry / Wet and the always-on Limiter. Recodec is built for fast experimentation. The classic interface keeps the core controls close, supports mono and stereo operation, includes factory presets across multiple categories, and lets you save your own user presets for quick recall. Recodec also includes MIDI Learn, Host Learn, CC assignment, and optional CC broadcast feedback for hands-on control workflows. Features: - Crusher for digital bit-depth style reduction - Reducer for sample-rate style degradation - Refine oversampling control - Drive, Bass, and Treble tone shaping - Dry / Wet blend and always-on Limiter - 35 factory presets across multiple categories - User preset save and recall - MIDI Learn, Host Learn, CC assignment, and CC broadcast - Mono and stereo operation Great for: - drums and percussion - vocals - synths and keys - bass and guitar - loops and transitions - creative sound design
