Choon is a cutting-edge AI application designed for DJs and music enthusiasts who struggle to manage large digital libraries. The platform integrates multiple technologies including metadata cross-referencing against Discogs' extensive database, direct audio analysis through Python DSP (BPM, harmonic content, energy), and machine learning models trained on obscure tracks. Choon's tagging system includes four dimensions: genre (with over 50 sub-genres), region, era, and vibe, which helps classify how a track functions in a set context such as peak time or after hours. The app offers a Mac companion for library management and syncing with Rekordbox, ensuring your tags are accessible during live performances. Choon ensures that no audio data leaves the user's device, maintaining privacy and security. It operates on a credit-based pricing model without subscriptions, offering reasonable rates.
