Asynchronous SPDIF Mixer

by DADDesign-Projects

"Asynchronous SPDIF Mixer" synchronizes and mixes up to three asynchronous S/PDIF streams into a 48 kHz output. Running on an STM32H743 and developed in C++ with CubeIDE, it compensates for drift with interpolation. A custom KiCad-designed PCB hosts this real-time audio processing solution.
