Mixboard Uses AI to Enable Anyone to Make Musical Mashups

The AI enables users to focus on developing the song instead of worrying about technical aspects and music theory. The app uses open-source music information retrieval libraries to determine song tempo, keys, and music stems, which help break down the song into individual mixes. The algorithm can stretch the sound to match the tempo or transpose keys to ensure both songs are in the same key. The researchers also provide templates of basic song structures to help users create an appealing track.
