Formats for signal data

Several competitions on Kaggle used sound data as an addition to regular tabular features. There were three competitions organized by Cornell Lab of Ornithology’s BirdCLEF (LifeCLEF Bird Recognition Challenge) in 2021, 2022, and 2023 for predicting a bird species from samples of bird songs (see Reference 4 for an example of one of these competitions). The format used in these competitions was .ogg. The .ogg format is used to store audio data with less bandwidth. It is considered technically superior to the .mp3 format.

We can read these types of file formats using the librosa library (see Reference 5). The following code can be used to load an .ogg file and display the sound wave:

import matplotlib.pyplot as plt
import librosa
def display_sound_wave(sound_path=None,
               text="Test", 
               color="green"):
    """
    Display a sound wave
    Args
        sound_path: path to the sound file...
