Worked on the Sonarr/Sonarr repository to enhance Kodi metadata generation by developing a dedicated audio codec formatter supporting advanced profiles such as Atmos and DTS-HD. Integrated this formatter into the existing XML serialization workflow, refining both audio codec and video framerate formatting for improved accuracy. Employed C# and NUnit to implement comprehensive unit tests, ensuring the reliability of new audio codec mapping logic and correct parsing of complex media information, including DTS-HD MA with DTS:X. Focused on backend development and code quality, these changes increased test coverage and improved metadata reliability, resulting in more accurate media data and better Kodi interoperability.
