tempograph comes in parts:
-
a dense text notation based on ffmpeg's filtergraph (
constant=120:start=1.0,linear=120:140:start=4b) to describe the tempo of a song (read more) -
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 (ideas)
- 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
