Visualizing audio data with matplotlib and Librosa

Visualizations play a crucial role in understanding and interpreting audio data. Here’s a comparison of different types of visualizations for audio data and their uses in various scenarios. The choice of visualization depends on the specific goals of the analysis, the nature of the audio data, and the intended application. Combining multiple visualizations can provide a comprehensive understanding of complex audio signals.

This section demonstrates how to visualize audio data, an essential skill in audio analysis.

Waveform visualization

A waveform is a simple plot that shows how the audio signal changes over time. It’s like looking at the ups and downs of the audio as a line graph. In other words, a waveform represents the amplitude of the audio signal over time:

import librosa
import librosa.display
import matplotlib.pyplot as plt
# Load an audio file
audio_file = "sample_audio.wav"
y, sr = librosa...
