Preprocessed Soundscape Datasets for Bird Sound Classification

soundscapes.zip contains evaluation soundscape datasets from the BIRB benchmark (https://arxiv.org/abs/2312.07439), downsampled to 16kHz, preprocessed using CNN14 from PANNs (https://arxiv.org/abs/1912.10211), to select a 6-second window with the highest bird activation, and converted to Pytorch (.pt) format to facilitate usability for evaluating deep neural networks. These datasets are prepared specifically for bird sound classification.

These preprocessed datasets are employed in the work "Domain-Invariant Representation Learning of Bird Sounds" (https://arxiv.org/abs/2409.08589), which assesss few-shot learning capabilities for transfer learning from focal to soundscape recordings.

Dataset Structure

Validation Dataset

• POW (pow.pt): Contains a dictionary with 'data' and 'label' keys representing the bird sounds and their corresponding labels. Source: https://zenodo.org/records/4656848#.Y7ijhOxudhE

Test Datasets 

Each test dataset folder contains numerous subfolders, with each subfolder named according to an eBird species code to represent data for a specific bird species.
