Worked on expanding audio data capabilities in the foxglove-sdk and mcap repositories, focusing on end-to-end audio capture, processing, and logging. Introduced a RawAudio schema to support raw PCM audio, enabling robust data serialization and cross-language compatibility. Enhanced the MCAP Demo Page to record and visualize audio, integrating React and TypeScript for frontend development and leveraging the Web Audio API for real-time processing. Delivered a Python example that generates and writes RawAudio messages to MCAP files, providing clear usage instructions and dependencies. Addressed schema field naming in Python class generation, improving reliability for developers working with audio data pipelines.
