Neural Style Transfer Audio Effect Kit with Arduino Due + LED
Build a Real-Time Neural Audio Effect: Arduino Due Kit for Timbre Transfer
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a guitar riff that leaves your instrument but arrives at the speaker with the spectral fingerprint of a violin, or your voice reshaped to carry the texture of a vintage synthesizer. This kit lets you build exactly that: a standalone audio effect unit that samples live sound, applies matrix convolution weights from a trained neural filter bank, and outputs a resynthesised timbre in real time. No laptop required once loaded — it’s a self-contained pedal-like processor powered by an Arduino Due and a quad DAC.
What You'll Build
You’ll create a hardware audio effects processor with a built-in microphone preamp, a 3W speaker output, and an OLED interface. Two rotary encoders let you scroll through preloaded neural weight sets and adjust wet/dry mix. The result is a tangible device that transforms mundane sounds into entirely new timbres, right at your desk or on stage.
What You'll Learn
- Sample audio in real time using Arduino Due’s ADC and DMA for low-latency capture
- Implement matrix convolution algorithms in C++ to apply neural filter bank weights
- Integrate I2C devices: MCP4728 quad DAC for high-quality output and 0.96” OLED for visual feedback
- Design, solder, and enclose a complete audio effects unit from prototyping boards to a finished box

Who This Kit Is For
Engineers and researchers diving into real-time audio DSP and neural networks will find this an ideal testbed. It suits final-year B.Tech ECE/EEE projects at IITs, NITs, VIT, or BITS, and tackles signals-processing challenges in Smart India Hackathon. Makers who have moved beyond basic Arduino and want to explore hardware-based audio ML will appreciate the depth.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
The AI companion provides step-by-step guidance, and you can send a WhatsApp message to our team for direct help from an engineer who knows this kit inside out.
Do I need prior experience with digital signal processing?
You’ll get the most out of the kit if you’re comfortable with C++ and basic DSP concepts, but the AI companion explains convolution, filter banks, and weight loading in clear, practical terms as you build.
Can I load my own neural network weights?
Absolutely. The kit includes a Python script that converts custom trained weights into a binary format the Arduino Due reads from its flash memory. The OLED menu lets you switch between weight sets on the fly.
Is the effect truly real-time?
With optimized code, the sampling, convolution, and DAC output run at a 16 kHz rate with latency well under 10 ms — making it feel immediate for live performance or monitoring.
Arduino Mega samples audio, applies matrix convolution weights from trained filter bank, outputs resynthesised timbre.
