People often record to a click so that a timing reference will be available later. When Apple loops are imported, as these already contain information regarding their tempo – here, again, further analysis of the tempo would be pointless.When an assignment file containing the results of a previous detection and any editing thereof has already been saved for the new audio file – here the tempo has been detected already so there is no need to repeat the process.No tempo detection is performed in two cases: The audio file runs in sync without your having to give it a moment’s thought.
Melodyne detects the tempo of the music and adjusts it to that of your project (even if this includes gradual tempo changes). Example: Drag a recording, a phrase or a loop into a document in the stand-alone implementation of Melodyne. Melodyne’s tempo detection and tempo adjustment functions are used often and to great effect, yet they execute for the most part quietly in the background.
