TuneMirror - TuneMirror is a local offline pitch analysis tool.

There is currently a highly popular singing reality show in my country, but it has drawn skepticism from viewers who suspect that some singers are relying on Auto-Tune or similar pitch-correction software. This prompted me to develop an automated and quantifiable way to gauge a singer's pitch accuracy and provide a baseline for detecting whether their vocals have been altered. The tool is based on the pYIN algorithm. Please keep in mind that this was developed rather quickly, so there may be critical bugs or inaccurate results. It is intended for reference only, and I would greatly appreciate any feedback or suggestions for improvement.
