The system compensates for drift and uses interpolation to ensure smooth audio transitions. The software, developed in C++ with CubeIDE, is optimized for real-time audio processing and runs on an STM32H743 microcontroller. A custom electronic board, designed with KiCad, has been developed to host this solution and provide a tailored hardware platform.\n\n![Image1](Images/PCBMixSmall.jpg) ![Image1](Images/Mixer.jpg)\n## Author\nThis project is developed by **DAD Design**.\n## License\nThis project is licensed under the [MIT License](LICENSE).\n## Evolutions\nRecent updates to the project include:  \n- **Addition of a third input**: Support for an additional audio stream has been integrated.  \n- **Development of a dedicated PCB**: A printed circuit board (PCB) has been designed to host the software.  \n\n## Features\n- **Synchronization of Asynchronous S/PDIF Streams:**  \n  The project synchronizes three input audio streams, each potentially running at different sample rates (96kHz, 48kHz, 44.1kHz, 32kHz), into a unified output stream at 48kHz.\n  \n- **Clock Drift Compensation:**  \n  Drift between the input streams is handled through periodic drift factor recalculation, ensuring the output remains smooth and synchronized.\n\n## Hardware Platform\nThe `KiCAD` folder contains the schematics and PCB files for the project's hardware. These files were created using **KiCAD version 8.0**.\n\n## Development Environment\nThe project is developed and compiled using the **CubeIDE** environment provided by STMicroelectronics. CubeIDE is a fully integrated development environment (IDE) that supports STM32 microcontrollers and provides tools for debugging, flashing, and developing embedded systems.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdaddesign-projects%2Fasynchronous-spdif-mixer","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdaddesign-projects%2Fasynchronous-spdif-mixer","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdaddesign-projects%2Fasynchronous-spdif-mixer/lists"}
