1.0

This is the first release of the 1.0 series. It is identical to 0.6.0.

BirdVoxDetect is a pre-trained deep learning system which detects flight calls from songbirds in audio recordings, and retrieves the corresponding species. It relies on per-channel energy normalization (PCEN) and context-adaptive convolutional neural networks (CA-CNN) for improved robustness to background noise. It is made available both as a Python library and as a command-line tool for Windows, OS X, and GNU/Linux.

The main developer of BirdVoxDetect is Vincent Lostanlen, scientist at CNRS, the French national center for scientific research.

As of v0.4, species classification in BirdVoxDetect relies on a taxonomical neural network (TaxoNet), which is distributed as part of the BirdVoxClassify package. For more details on TaxoNet, please refer to:

0.6.0

This is the first stable release of the 0.6 series.

The main change with respect to the v0.5 series is the update from BirdVoxClassify v0.2 to v0.3. The species classifier is now "flat multitask" by default and includes hierarchical consistency. Furthermore, the order "Passeriforme" is now spelled in the plural: "Passeriformes". We have added various encodings for species: English name, scientific (Latin) name, and 4-letter code (#85). The "other" class is represented as an empty string. Lastly, we have truncated the number of digits of confidence in the checklist (#86).

0.6.0b1

This is the first beta release of the 0.6 series.

The main change with respect to the v0.5 series is the update from BirdVoxClassify v0.2 to v0.3. The species classifier is now "flat multitask" by default and includes hierarchical consistency. Furthermore, the order "Passeriforme" is now spelled in the plural: "Passeriformes". We have added various encodings for species: English name, scientific (Latin) name, and 4-letter code (#85). The "other" class is represented as an empty string. Lastly, we have truncated the number of digits of confidence in the checklist (#86).

0.6.0a5

This is the fifth alpha release of the 0.6 series. It fixes a bug in the species classifier (#90), triggered at the edges of the recording (bis).

0.6.0a4

This is the fourth alpha release of the 0.6 series. It fixes a bug in the species classifier (#90), triggered at the edges of the recording.

0.6.0a3

This is the fourth alpha release of the 0.6 series. It fixes an important bug in the encoding of the species classifier (BirdVoxClassify), triggered when the flight call is not a passeriforme ("0.*" taxonomy tags).

0.6.0a2

This is the third alpha release of the 0.6 series. It is functionally identical to 0.6.0a1, with some changes to the README page.

0.6.0a1

This is the second alpha release of the 0.6 series. It fixes an issue regarding the conversion of BirdVoxClassify output probabilities to percents.

0.6.0a0

This is the first alpha release of the 0.6 series.

The main change with respect to the v0.5 series is the update from BirdVoxClassify v0.2 to v0.3. The species classifier is now "flat multitask" by default and includes hierarchical consistency. Furthermore, the order "Passeriforme" is now spelled in the plural: "Passeriformes". We have added various encodings for species: English name, scientific (Latin) name, and 4-letter code (#85). The "other" class is represented as an empty string. Lastly, we have truncated the number of digits of confidence in the checklist (#86).

0.5.1

This is the first bugfix release of the 0.5 series.

In comparison with 0.5.0, we have changed the default classifier: it is no longer TaxoNet but "flat multitask". In doing so, we revert to the species classifier that was already present in BirdVoxDetect 0.3.0. We have made this change because we have noticed a surprisingly poor performance of TaxoNet on hold-out data. Thus, we err on the side of caution and offer a more straightforward deep learning model as the new default. We are currently investigating the cause of the problem in coordination with BirdVoxClassify developers.
