Once it's not a rats nest of cables I'll post the instructions on how I did that, but honestly there isn't much to it. import numpy as np from scipy.io.wavfile import write from scipy import signal # Parameters for the brown noise generation sample_rate = 44100 # Sample rate in Hz duration_hours = 1 # Duration of the audio in hours noise_length = duration_hours * sample_rate * 3600 # Total number of samples # Generate white noise white_noise = np.random.randn(noise_length) # Define frequency bands and corresponding low-pass filter parameters freq_bands = [5, 10, 20, 40, 80, 160, 320] # Frequency bands in Hz filter_order = 4 low_pass_filters = [] for freq in freq_bands: b, a…
