Developed WebM audio read and write support for the mlx-audio repository, expanding its audio processing capabilities to handle browser-generated audio blobs. The implementation leveraged the existing ffmpeg-based decode and encode pipeline, ensuring no new dependencies were introduced while maintaining compatibility with outputs from browser MediaRecorder. Comprehensive tests were added to validate the new WebM workflow, confirming correct handling of both reading and writing operations. The work was completed using Python, with a focus on robust audio processing and thorough testing practices. This update addressed the need for seamless integration of WebM audio formats within the existing processing framework.
