NBMSet24: Nocturnal Bird Migration Dataset

Boxed annotation from : https://arxiv.org/abs/2412.03633

Dataset architecture and BuilderScript is inspired from BirdSet https://huggingface.co/datasets/DBD-research-group/BirdSet

How to download this dataset?

Install huggingface datasets package: pip install datasets

Run this python code:

from datasets import load_dataset

dataset = load_dataset(
    path="ppeyret/NBMSet24",
    name="NBMSet24",
    cache_dir="path/to/where/you/want/your/cached/data",
    num_proc=None, # put and integer (number of workers) here if you want to use multiprecessing
    trust_remote_code=True
)

Changes compared to Zenodo database

Changes compared to original dataset in Zenodo:

• Audio data have been converted to mono and resampled to 32kHz
• Frequency values of annotations with low_freq or high_freq > 16kHz have been set to 16kHz.
• Label mispelling corrections
• Annots with low_freq or high_freq to -1 (due to audacity bug) have been corrected
• Removed audio files that have no annotations

Still need to fix:

• Some original annotations have no label. They have been mapped to the class "other" for now.

Caution:

The species list is different between train and test splits:

Species of test split that are not in train split:

{'Buteo buteo', 'Podiceps cristatus'}
