Polymath is a open-source tool that uses machine learning to convert any music library (e.g from Hard-Drive or YouTube) into a music production sample-library.
The tool automatically separates songs into stems, quantizes them to the same tempo and beat-grid and analyzes musical structure, key, and other infos. The result is a searchable sample library.
