Apple Soundtrack Pro 3 - Manual (Page 208)

You can open and edit an audio file with up to 24 channels in the File Editor, view it in
Waveform or Frequency Spectrum view, process the file using actions, analyze it for
common audio problems, fix analyzed problems individually or together, and then save
the edited file as an audio file project or as a standard audio file. And you can do all this
while working interactively with same audio file in the multitrack Timeline and while
hearing (and seeing) the file in the context of other audio files in a multitrack project.
