To develop a genuine random number generator in Python by utilizing ambient noise such as recorded MP3 or wave files, you can follow these steps:

  1. Import necessary libraries - wave, numpy, and random.
  2. Read the audio file using the wave library.
  3. Extract the audio frames using the readframes() function.
  4. Convert the frames to integers using the frombuffer() function.
  5. Generate a random sequence of integers using numpy's randint() function.
  6. Choose a random starting index within the audio frames.
  7. Create a loop to combine the randomly generated integers with the audio frames in a new list.
  8. Shuffle the elements in the list using random.shuffle().
  9. Use the shuffled list as a seed for random.seed().
  10. Generate your random numbers using the random() function.

Here's a sample code:

import wave
import numpy as np
import random

def get_random_number(audio_file):
    # Step 1: Import necessary libraries
    # Step 2: Read the audio file
    with wave.open(audio_file, 'rb') as wav_file:
        # Step 3: Extract the audio frames
        frames = wav_file.readframes(-1)
        # Step 4: Convert frames to integers
        int_frames = np.frombuffer(frames, dtype='int16')

        # Step 5: Generate a random sequence of integers
        rand_seq = np.random.randint(0, 32767, len(int_frames))

        # Step 6: Choose a random starting index
        start_index = random.randint(0, len(int_frames) - len(rand_seq))

        new_seq = []

        # Step 7: Combine randomly generated integers and audio frames
        for i in range(len(rand_seq)):
            new_val = (rand_seq[i] + int_frames[start_index + i]) % 32767
            new_seq.append(new_val)

        # Step 8: Shuffle the list
        random.shuffle(new_seq)

        # Step 9: Set the shuffled list as the seed
        random.seed(new_seq)

        # Step 10: Generate a random number
        return random.random()

Note: this method may not produce truly random numbers, as the ambient noise might contain patterns or biases. Additionally, the randomness of this method may depend on the quality of the audio file and the method used to record it. It's always best to evaluate the randomness of any random number generator before relying on it for security or other critical applications.
