Are you interested in FPGA development, digital audio processing, and hands-on electronics projects? This Elektor Lab Talk with Dr. Christian Nöding will leave you inspired. He takes us on his exciting journey into FPGA-based real-time audio mixing, using the Arduino MKR Vidor 4000. Starting from scratch, he dived into VHDL programming and achieved a fully functional real-time audio mixer with a 20-microsecond latency.

In the video, he explains why FPGAs are ideal for this kind of applications and details how I²S and AES3 (Ultranet) signals are handled within the FPGA, allowing multi-channel audio processing. The project includes volume control, equalization, mixing, as well as a web-based user interface. Don’t miss the live demo!

Beyond the core project, Christian also unveils an ambitious expansion: integrating his FPGA-powered system into a Behringer digital mixer, effectively doubling its channel capacity to 64 inputs while adding DMX512 lighting control. You also can visit his YouTube channel for more information.

As usual in Elektor Lab Talk, our editors also chat about Elektor Magazine news, such as highlights from the March-April edition, including RISC-V development boards, AI at the edge, the Embedded World trade show, and much more. Whether you're looking to start an FPGA project yourself or simply curious, don't miss this exciting episode packed with technical insights, watch the video below.
