Background Library 01 consists of

BL01 >> BL_CHVACH_free_final:
54 hand-cleaned (Vanellus chilensis-free) background files and

BL01 >> PSC008_forest:
36 original soundscapes recorded inside forest, which may contain a few target signals from overflying lapwings.

Contains the Excel files
- 2013CHVACH_BreedingCycle_Statistics_PONE: statistics on V. chilensis activity patterns, Apr. 2013 to Sep. 2013.
- 2013CHVACH_FalseNegatives_PONE: determination of the false negative rate based on an expert-annotated sample of 26 soundcsape recordings
- 2013CHVACH_FalsePositives_PONE: determination of the false positive rate based on an expert-annotated random sample of 1250 automated V. chilensis detections.

Training library for the development of the V. chilensis recognizer, consisting of 90 hand-filtered recordings of the target species.

VACH_Detector_results >>
TXT detector output files, listing timestamps of potential V. chilensis sound events.

Validation library used to determine the false negative rate. The library consists of 26 expert-annotated sound files. Annotations were made in Adobe Audion v3.0.

Validation library used for the fine-tuning of the recognizer settings.

Important notes on the annotation of the VACH_FNrate_20160706 library:

1) In general, we used the procedure described in Ganchev et al. 2015 for the annotation of VACH validation libraries (see next section).

2) However, the detector-generated timestamps were not changed! For the following reasons, it is not possible to use the VACH_FN_rate library as a validation library for the development of improved recognizer versions:

(a) The VACH detector overlooked many of the weaker signals within a VACH call series. Therfore the detector-generated annotations are incomplete.
(b) For the same reason some automatically-generated detections may refer to a single VACH call event (double hits).

Details on the method used for the annotation of the VACH validation libraries are described in Ganchev et al. 2015, pp.6100f: chilensis validation dataset.
