While AI technology is advancing rapidly, it is not likely that it will completely replace mixing engineers anytime soon.
While AI can automate certain tasks in the mixing process, such as identifying frequencies and adjusting levels, it still lacks the creative decision-making abilities and subjective judgment that mixing engineers bring to a project.
Mixing is an art as much as a science, and it requires human intuition and creativity to make the right choices for a particular song or recording.
AI can certainly assist in the mixing process and make it more efficient, but it is unlikely to fully replace the human touch in the creative process. Additionally, many musicians and artists value the collaboration and personal touch that comes with working with a skilled mixing engineer.
