Beat Tracking

Coursework 1 : Music Informatics (2021) Queen Mary University of London

Dynamic Programming implementation and evaluation of Dan Ellis (2007) Beat Tracking algorithm [1].

Requirements

• python3
• librosa
• mir_eval

Runing

To run the program against a single file:

$ make track-beat AUDIO_FILE=<path-to-audio-file>

The program is also callable from a python environment as follows:

beats = beatTracker(<path-to-audio-file>)

To run the program against the entire Ballroom dataset:

make track-all

Evaluation

To evaluate a single run you must have your estimates and your ground truth sequences in local files and the evaluator can be evoked by running:

$ make eval-one BEAT_ESTIMATE=<path-to-estimate-sequence> BEAT_GROUND_TRUTH=<path-to-ground-truth>   

To evaluate all outputs in the given dataset and produce relevant box plots:

$ make eval-all
