Generating audio signals

Now that we know how audio signals work, let's see how we can generate one such signal. We can use the NumPy package to generate various audio signals. Since audio signals are mixtures of sinusoids, we can use this to generate an audio signal with some predefined parameters.

Create a new Python file and import the following packages:

import numpy as np 
import matplotlib.pyplot as plt 
from scipy.io.wavfile import write 

Define the output audio filename:

# Output file where the audio will be saved  
output_file = 'generated_audio.wav' 

Specify the audio parameters such as duration, sampling frequency, tone frequency, minimum value, and maximum value:

# Specify audio parameters 
duration = 4  # in seconds 
sampling_freq = 44100  # in Hz 
tone_freq = 784  
min_val = -4 * np.pi 
max_val = 4 * np.pi 

Generate the audio signal using the defined parameters:

# Generate the audio signal 
t = np.linspace(min_val, max_val, duration * sampling_freq) 
signal = np...
