Question: Is there a music analysis tool that can separate audio tracks into individual instruments?

Cryo Mix is a powerful AI-based music mixing and mastering tool that includes an AI Audio Separator. It can break down stems like vocals, drums and instruments from a single file using machine learning technology. It's got an interface that's easy to use, too, and other features like pitch correction and final mix preparation.

Another tool worth a look is AudioShake, which is geared specifically for audio separation and isolation. It can recognize and isolate audio elements from files up to 192kHz, so it's good for a variety of tasks, including making instrumentals and analyzing audio.

If you want something a bit more streamlined, LALAL.AI offers a fast and accurate way to split an audio file into vocal and instrumental tracks. You can upload multiple files and choose from a variety of stem options for fast processing and good results. The service is geared for musicians, streamers and transcribers.

Last, RipX DAW offers stem separation and editing. It lets you edit notes one at a time and replace instruments, which is good for producers, DJs and musicians. The PRO version adds other tools like audio repair modules and effects for more serious musicians.
