Miles contributed to the foxglove-sdk and mcap repositories by developing end-to-end audio data capture and processing features. He introduced a RawAudio schema to support logging and handling of raw PCM audio, and enabled audio recording with visualization and UI state management in the MCAP demo page. Using TypeScript, Python, and the Web Audio API, Miles ensured cross-language compatibility and robust data serialization. He also fixed schema field naming in Python class generation to prevent errors, and created a Python example for writing RawAudio messages to MCAP files. His work provided reusable references and accelerated onboarding for audio data workflows.
