Annotation Files
------------

Transcriptions were produced using Sonic Visualiser: https://www.sonicvisualiser.org/ by an experienced birdwatcher, Hanna Pamula.

Number of missing annotations: 13 (6 of these files contained sounds which could not be unambiguously labelled and the rest 7 of them only included insects)

The original (weak) labels provided during the NIPS4B 2013 challenge were used for guidance. However, some files were judged to have a slightly different set of species present than was given in the original metadata.

Extra Unknown label was added to the dataset for the vocalisations that couldn't be classified to a specific species. Also, extra Human label was added for a few recordings that had human sounds present in them.

Transcription format:
[Starting time (sec)],[Duration of event (sec)],[Label]
