# Beat Tracking Evaluation Toolbox

This repository implements a number of beat tracking evaluation methods, described in a summary paper:

- Evaluation Methods for Musical Audio Beat Tracking Algorithms, Matthew E. P. Davies, Norberto Degara and Mark D. Plumbley, Technical Report C4DM-TR-09-06, 2009

Implementation by Adam Stark and Matthew Davies

## Install

Run:

pip install beat-tracking-evaluation

## Running the code (Python)

First, import the library:

import beat_evaluation_toolbox as be

Then, evaluate beat estimations on database of beat annotaions as follows:

R = be.evaluate_db(annotations, beats, measures, doCI)

where the arguments are as follows:

- 'annotations' is a list of numpy arrays containing the beat annotations for the database
- 'beats' is a list of numpy arrays containing the beat estimations for the database
- 'measures' is a list of strings indicating which evaluation measures to use. Setting measures='all' calculates all measures. Specific measures can be chosen by setting measures = ['fMeasure','cemgilAcc','gotoAcc','pScore','continuity','infoGain','amlCem'] or a subset thereof.
- 'doCI' is a boolean indicating whether or not to calculate confidence intervals

and the returned value is:

- 'R' is a dictionary containing all results

All results will be printed to the terminal once the evaluation is complete.
