tempograph comes in parts:
-
a dense text notation based on ffmpeg's filtergraph (
name=value:any_key=value) to describe the tempo of a song (constant or variable) -
a software library which can query information about notated tempo (x beat's time, total beat count at x time, total time at x beats...) using analytical evaluation of the notation as an integral
-
a graphical interface to make tempo notation easy
- Force Dynamics of Tempo Change in Music, 1992 (Jacob Feldman, David Epstein and Whitman Richards) is a covered application of manual tempo notation and analysis
