Lines 30-34:
Line 31 & 33 why 2*np… and 2 * np… these are different syntax?

Check if syntax is intentional if not change it to python style guide.

    if 'Mono' in answers['tests']:
        # Create test files
        # Random to simulate dither
        sf.write('silence.aiff', (2*np.random.default_rng(42).random((4410))
                 - 1) / 10000, 44100, 'PCM_16')
        sf.write('white.aiff', 2 * np.random.default_rng(42).random((4410))

• Look up python style guide in finished issues in project
• Change syntax to conform to style guide
