Tapes is a local-first audio workspace bringing professional studio tools to mobile. It uses on-device AI for stem separation, audio-to-MIDI conversion, and noise reduction. Key features include a multi-track studio view, real-time BPM/key detection, and harmonic scouting for sonic matching. Unlike cloud-based alternatives, Tapes processes all audio locally, ensuring privacy and offline performance. It is a comprehensive toolkit for mobile producers and field recorders.
