Music producer builds audio analyzer CLI without typing code—github copilot turns devs into prompt therapists, bugs into group therapy

A music producer has developed an audio analyzer tool called mixref through conversation with GitHub Copilot CLI, a tool that generates code based on plain language descriptions. The mixref tool analyzes audio files, providing loudness metrics, BPM detection, musical key, and spectral analysis. It was built entirely through conversation, with the developer describing what they wanted in plain language, and GitHub Copilot CLI generating the code. The tool has 750 lines of source code, 154 tests, and 19 modules, and is available on PyPI and GitHub. The developer found that building features was much faster using GitHub Copilot CLI, and that the generated code followed conventions and had good test coverage. The project demonstrates the potential of AI-assisted development, allowing developers to focus on describing problems and reviewing solutions rather than typing code. The mixref tool is a functional audio analysis tool that can be installed using pip install mixref.
