Question: Is there a DJ software that uses AI to isolate beats, instruments, and vocals from songs in real-time?

If you're in the market for a DJ software that uses AI to extract beats, instruments and vocals from songs in real-time, djay is a good choice. It's got a technology called Neural Mix that separates music sources in real-time. The software runs on a variety of devices, including Mac, Windows, iPad, iPhone and Android. Djay also can tap into Apple Music for a large library of songs, and it's a full-featured DJing tool with options like cue points, looping and effects.

Another good option is Moises, an AI-based audio processing and separation tool. Moises can separate vocals, drums, guitar, bass and other instruments in real-time, which is useful for musicians who want to practice in a different key or tempo. It runs on multiple devices, including mobile apps and web interfaces, and lets you securely log in to a private library.

If you're looking for more advanced stem editing and sound replacement, check out RipX DAW, an AI-based music production tool that can dissect mixed audio into stems and then edit each stem note by note. It's geared for serious producers, DJs and musicians who need fine control over their audio.

Last, Fadr is a web-based tool that offers a collection of AI-based music tools, including a vocal remover, song splitter and key/tempo/chords detector. It's good for people who want to make remixes and mashups, and stem extraction for different audio elements. Fadr also has a DJ tool for live performances, so it's good for creative music production.
