import numpy as np
from scipy.io import wavfile
from sklearn.decomposition import FastICA

# Load the mixed audio file
rate, mixed = wavfile.read('mixed_audio.wav')

# Apply Independent Component Analysis (ICA)
ica = FastICA(n_components=1)
source = ica.fit_transform(mixed)

# Save the separated source audio
wavfile.write('separated_audio.wav', rate, np.int16(source))

print("Separation completed!")

Stuff to consider:

To use this program, you’ll need to have the numpy, scipy, and scikit-learn libraries installed. Additionally, you should have a mixed audio file named 'mixed_audio.wav' in the same directory as the Python script. This audio file should contain the recorded audio in a crowded room where a single speaker is talking.

The program uses the wavfile module from scipy.io to read the mixed audio file. It then applies Independent Component Analysis (ICA) using the FastICA class from sklearn.decomposition to separate the source audio from the mixture. Finally, it saves the separated audio as 'separated_audio.wav' and prints a completion message.

Make sure to replace 'mixed_audio.wav' with the actual filename of your mixed audio file before running the program. Additionally, you may need to install the required dependencies if they are not already installed.

Please note that the success of the cocktail party problem depends on various factors such as the quality of the recording, the number of speakers, and the level of background noise. The program provided serves as a basic example, and you may need to experiment with different algorithms or parameters to achieve satisfactory results in real-world scenarios.
