Audiotool
Audiotool is an online music production studio. It is an advanced music mixing space, and is posted here as a tool for teachers as opposed, not as a resource for students. Their privacy policy isn’t quite where we need it to be for student use. Because of the advanced nature of the tool, it would be a very rare circumstance that this tool would be beneficial in the classroom. However, it may be of great value to a music teacher.
