phase, magnitude, audio file and information
As the comments said. "monoaural phase" is not very important and monoaural phase changes are often inaudible. "binaural" phase is very important for localisation and imaging, particularly in stereo files.

"monoaural" means the phase of a single channel or that the same phase shift or modification is applied to all channels the same way.

"binaural" means specifically the difference in the signal at the left and the right ear.
