White Noise Generation

Program Features

  • A program that generates 5 different types of noise.
  • Composed of 3 functions for noise sample generation, applying a bandpass filter, and saving the generated samples.
  • The generated noise is saved in WAV file format.

Key Features

  • Configure the sampling rate and length of generated samples.
  • Choose from 3 weighting filters.
  • Specify the sound volume when saving samples (in dB).

How to Use

Each function can be used step by step. You can test all the processes by running the noise_generator.ipynb file.

1) main.py

a) generate_sample

  • Generate noise samples.
    • sec: Duration of the noise to be generated.
    • sample_rate: Sampling rate.
    • color: Type of noise.
    • weight: Type of weighting filter.

b) bandpass_filter

  • Apply bandpass filtering on frequency domain.
    • samples: Generated samples.
    • lowcut: Lower frequency for filtering.
    • highcut: Upper frequency for filtering.

c) save_sample

  • Save the samples as WAV files.
    • samples: Generated samples.
    • db: Sound volume level.
    • file_name: Name of the file to be saved.
