Estimation of Tempo, Micro Time and Time Signature from Percussive Music
نویسندگان
چکیده
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.

A Mid-Level Representation for Capturing Dominant Tempo and Pulse Information in Music Recordings
Automated beat tracking and tempo estimation from music recordings become challenging tasks in the case of nonpercussive music with soft note onsets and time-varying tempo. In this paper, we introduce a novel mid-level representation which captures predominant local pulse information. To this end, we first derive a tempogram by performing a local spectral analysis on a previously extracted, pos...
متن کاملTempo Detection of Urban Music Using Tatum Grid Non Negative Matrix Factorization
High tempo detection accuracies have been reported for the analysis of percussive, constant-tempo, Western music audio signals. As a consequence, active research in the tempo detection domain has been shifted to yet open tasks like tempo analysis of non-percussive, expressive, or non-western music. Also, tempo detection is included in a large range of music-related software. In DJ software, fea...
متن کاملTempo Tracking With a Periodicity Comb Kernel
Automatic tempo extraction and beat tracking from audio is an important ability, with many applications in music information retrieval. This paper describes a method for tempo tracking which builds on current research in the field. In this algorithm, an autocorrelation surface is calculated from the output of a spectral energy flux onset novelty function. The most salient repetition rate is cal...
متن کاملA Two-Fold Dynamic Programming Approach to Beat Tracking for Audio Music with Time-Varying Tempo
Automatic beat tracking and tempo estimation are challenging tasks, especially for audio music with timevarying tempo. This paper proposes a two-fold dynamic programming (DP) approach to deal with beat tracking with time-varying tempo. In particular, the first DP computes the tempo curve from the tempogram. The second DP identifies the optimum beat positions from the novelty and tempo curves. E...
