Worked on the Blaizzy/mlx-audio repository to implement a length alignment mechanism for the SineGen module, ensuring generated sine waves accurately match the input f0 sequence length across various TTS backends. Developed a helper function to handle padding and truncation, and introduced a dedicated test suite using Pytest to validate cross-model consistency and reliability. Addressed a length alignment bug, resulting in improved compatibility and reduced integration risk for downstream audio processing pipelines. Enhanced code quality by clarifying the API, updating documentation, and adopting a test-driven approach. Utilized Python, MLX, and unit testing to deliver maintainable and robust audio generation features.
