METHOD AND APPARATUS FOR ENABLING A USER TO AMEND AN AUDIO FILE

摘要

A method and apparatus for enabling a user to amend an audio file via a user interface for controlling a drive for re-authoring the audio file. The method comprising: a) associating icons on a display of the user interface with one or more instruments or sets of instruments in the audio file; b) the user selecting an icon (103); c) the user assigning a position to the icon (105) on the display to indicate the virtual position relative to the user of the associated instrument/s; d) the user assigning a trajectory to the icon (107) from a selection of provided trajectories that define the virtual path relative to the user of the associated instrument/s; e) indicating on the display the position of the icon and whether a trajectory has been assigned to the icon. This can be used in applying three-dimensional audio data to a MIDI file.
