Estimation of tempo, micro time and time signature from percussive music
Tempo, micro time and time signature are basic rhythmic features for a wide range of music. Their automated extraction from music is needed for a number of applications, e.g. automatic transcription and music information retrieval systems, authoring tools, entertainment applications, musicological analysis or educational purposes. The presented analysis procedure estimates tempo, micro time and time signature from percussive music. From 117 excerpts of eight seconds length, 84.6% of the tempo values, 83.8% of the micro time and 73.5% of the time signatures were estimated correctly.
