Birdsong NOIZEUS: Bioacoustics noise reduction benchmark dataset

------------------------------------------------------------------------
Birdsong noizeus dataset
------------------------------------------------------------------------

Authors: Tim Sainburg & Asaf Zorea
Year: 2024

------------------------------------------------------------------------
General information
------------------------------------------------------------------------
- There are 5 recordings from each of 14 individuals (European starlings) recorded in an acoustically isolated chamber. 
- For each song, we apply noise at 5 SNR levels (0dB, 5dB, 10dB, 15dB). 
- There are 8 noise types, each taken from a single noise clip from the "Soundscapes from around the world" dataset.
- They are "rain", "town", "wind", "waterfall", "insect", "swamp" "frogscape", "forest"
- Each soundscape contains multiple noise sources. 
- Noise levels were estimated using the pyloudnorm software (Steinmetz et al., 2021)
- Audio is provided as waveforms at 44100 samplerate

Data format
------------------------------------------------------------------------

- clean
    - {bird_name}_{timestamp}.wav
- noisy
    - {snr}dB
        - {bird_name}_{timestamp}_{noise_category}_{snr}.wav
- noise_sample
    - {snr}dB
        - {bird_name}_{timestamp}_{noise_category}_{snr}.wav

`clean` contains the original clean audio.
`noisy` contains the song+noise
`noise_sample` contains a 1-second sample of noise only. 

Timestamp is in the format YYYY-MM-DD_HH-MM-SS-MILLISECONDS and refers to the time that the song was recorded.

We sampled 8 soundscapes from this dataset:
    1. Rain https://www.gbif.org/occurrence/4523646364
        - Virginia
        - 457s
        - rain, Recording of the feeders in the backyard with a light rain falling on the leaf litter, while a freight train passes by ~1/2 mile away.
    2. Town https://xeno-canto.org/696263
        - 2:22
        -  the closer habitat are greater trees and coniferes ..smaller bushes ...some other Krautgärten ... traffic-noise is to hear..as airplanes,too.
        - insects, birds, bells, traffic?, airplane
