If you want software to edit notes in a stem without affecting the rest of the track, RipX DAW is a great choice. This AI music production software offers advanced stem separation and note-by-note editing. You can split mixed audio into stems, replace instruments or vocals, and with the PRO version, get stem clean-up and audio repair modules.
Another option is Cryo Mix, which offers a collection of AI tools for mixing and mastering music. That includes an AI Audio Separator that isolates stems from a single audio file so you can edit one part of your track without affecting others. Its interface is easy to use, and the adjustments are made with industry-standard controls, so it's good for beginners and pros.
If you prefer a web-based option, Databass AI offers a variety of AI tools right in your browser. That includes a Stem Splitter and a Text-to-Audio tool so you can isolate and edit specific elements of your audio without affecting the rest of the track. That makes it a good choice for producers who want to experiment with new ideas or try out different styles without a lot of setup or training.
