TEMPO EXTRACT

[Wayne Bangert]

I have been using AUDIO SNAP functions to create a tempo map for a all audio file with 10 audio stems. The drum track has straight forward with Bass, Snare.  I run AUDIO snap to extract the location of the 1/4 notes in each measure. I have had good luck with this feature and I am able to add midi tracks to the file at the correct tempo. I noticed in several cases the file may have a tempo of 105 bpm as based on the real world count of the song. After running AUTOSNAP to extract the tempo the resulting tempo then is 54 bpm on average and the real world tempo count is unchanged.  . Granted everything is playing in tempo but why the reduction in tempo count?

Audiosnap's analysis is sometimes off by factor of two. Before doing tempo extraction or any other operation with Audiosnap you should choose the correct Average Tempo from the pick list in the Audiosnap Palette (or in the bar at the bottom of the clip when 'Edit Clip Map' is enabled in the palette).

David,

Thanks, that worked. Do you know of any video instructions on using audiosnap? I just do not know much about this feature.

Audiosnap is a collection of tools for manipulating audio and project timing in different ways. The appropriate functions and steps to use in a given situation depend on the starting point and the goal, and it would be difficult to cover all the possible scenarios in a single video.  I learned it by experimenting with it. There's a lot of random stuff on Youtube that is more or less (sometimes much less!) correct, depending on who posted it. For a general overview of what it can do, I would actually start with this ancient video by Seth Perlstein on Cakewalk's channel; The UI is a more than a bit out of date, but the overall capcbilities and usage have not changed that much:
