Products of Synthux Academy
Synthux Academy is an educational nonprofit organization based in Rotterdam, The Netherlands. The Academy teaches sound design and how to program your musical instrument. Synthux DIY kits were created following six years of research at Design Academies around the world. The DIY kits were tested by thousands of students and teachers around the world who made their own unique twist to the instrument. Synthux Academy offers three DIY kits: Simple Fix Kit, Simple Touch Kit, and Simple Designer Kit. No prior technical knowledge is required to enjoy these powerful programmable musical instruments. The kits were designed to serve as your first synth DIY kit as well as a powerful tool for a more advanced creator. Each kit comes with a free video course teaching sound fundamentals. https://learn.synthux.academy/ For videos, live streams, and exclusive online courses, visit Synthux Academy on YouTube. https://www.youtube.com/c/synthuxacademy

Synthux Academy - Audrey II
available
Horrorscape Synthesizer - sculpting feedback into sonic art!Audrey II is a horrorscape synthesizer designed for fearless exploration of feedback. Unpredictable yet compelling, it transforms chaotic sound into immersive soundscapes. From deep, haunting drones to screeching, otherworldly tones, Audrey II is a sonic beast like no other.Feedback Synthesis?What is feedback, really? It’s that magical moment when sound loops on itself, evolving into something wild. With Audrey II, we’re taking feedback to the next level using Karplus-Strong synthesis—a fancy term for turning short bursts of noise into rich, self-sustaining tones. Think digital strings, but way cooler.Digital WitchcraftSome say analog is the only way to get that sound… We were surprised too when we heard the first burst of noise coming through our headphones. That warmth, the grit, the unpredictability—it was all there. But here’s the twist: Audrey II is 100% digital, running on the almighty Daisy Seed platform.Built from the ground up to emulate analog chaos, digital bits power every nuance of Audrey II’s feedback, distortion, and reverb-drenched echoes. It’s pure digital magic that doesn’t just imitate analog—it embraces and amplifies it. What you hear isn’t just a close approximation; it’s a whole new breed of sound that pushes digital synthesis into uncharted territory.Pristine SoundPowered by the Daisy Seed microcontroller, Audrey II delivers 96kHz / 24-bit audio with the speed of an ARM Cortex-M7 at 480MHz. Equipped with 64MB of SDRAM, it handles complex feedback, drones, and effects seamlessly, pushing digital synthesis into rich, analog-like territory.The Signal Flow01. Karplus-Strong Synthesis & DistortionThe signal begins with Karplus-Strong synthesis, a method of string synthesis that creates resonant, droning tones—adding layers of harmonics to emulate organic vibrations, while feedback and distortion weave in raw, aggressive edges.02. ReverbNext, the signal passes through a rich, spacious reverb, allowing the drone and feedback to bloom, creating haunting and immersive atmospheres.03. FiltersFollowing the reverb, Audrey II utilizes high-pass and low-pass filters with a body control to shape the sound further, revealing hidden overtones and harmonic textures that can add either warmth or an eerie sharpness to the feedback.04. Tape Delay EmulationFinally, the signal reaches a tape delay emulator that further degrades and expands the sound, adding layers of movement, modulation, and a classic tape echo feel that’s both nostalgic and unpredictable.05. Stereo OutputTo top it all off, Audrey II’s stereo output widens the soundstage, creating a sense of depth and space that immerses you in rich, layered textures. With stereo feedback flowing through the chain, each element takes on new dimensions, allowing you to push the boundaries of sonic space.Driven & Open SourceAudrey II is a collaborative project born from the Synthux Academy community, where music technology enthusiasts, designers, and engineers come together to push creative boundaries. Developed by Nick Donadson from Infrasonic Audio and designed by Roey Tsemah, founder of Synthux Academy, Audrey II embodies the spirit of exploration and innovation that drives this community.Audrey II’s firmware is available on our GitHub, inviting anyone to dive into the code, make modifications, or build upon its foundation. This open-source approach empowers makers not only to experiment with Audrey II’s sound but to shape its future, contribute enhancements, and share discoveries with the Synthux Academy community. Audrey II is a testament to the creativity that can emerge from collective knowledge and a shared passion for instrument design.Features:• Karplus Strong synth engine• Reverb amount• Reverb size• High and low pass filters• Tape delay emulation• Stereo out• Built on the Daisy Seed• Open sourceDIY-Kit-Type:THT-Kit-1.
