Polymath utilizes machine learning to transform any music library (e.g., from your hard drive or YouTube) into a searchable sample library for music production. The tool automatically segments songs into drum beats, bass lines, and other audio elements, quantizes them to the same speed and tempo (e.g., 120 bpm), analyzes musical structure (e.g., chorus, verses), key (e.g., C4, E3), and other information (timbre, loudness, etc.), and converts the audio to MIDI. The result is a streamlined workflow for music producers, DJs, and ML audio developers.
