Description

Audrey II Desktop Feedback Synthesizer

The Synthux Audrey II is a desktop feedback synthesizer for evolving drones, ambient textures and resonant soundscapes. Built on the Daisy Seed platform, it combines a Karplus-Strong synthesis engine with reverb, high-pass and low-pass filters, tape delay emulation and stereo widening.

Explore eerie, tension-filled atmospheres or softer, tuneful resonances. Shape the feedback path, let the sound bloom through reverb and add dark, modulated repeats for a layered stereo texture.

Feedback Synthesis and Sound-Shaping Features

• Karplus-Strong engine: a noise burst feeds a short, resonant delay line, with amplitude and frequency controls.
• Reverb in the feedback path: soften and expand resonances into spacious drones.
• High-pass and low-pass filters: sculpt the feedback's spectral content and explore new harmonic tones.
• Tape delay emulation: add depth with dark, modulated repeats and push the delay into its own feedback for saturation.
• Stereo widening: create an immersive output field from layered textures.

From Resonant Tones to Ambient Soundscapes

Start with the noise excitation and short delay, then guide the resonances using the filters. Reverb creates a spacious bloom around the feedback, while the tape-style delay adds another layer of movement. Audrey II rewards attentive listening as you move between delicate tones and more intense feedback textures.
