What does a higher bit depth indicate in digitized sound?

Smaller file size

Lower quality reproduction

Faster sampling rate

More accurate sample (correct)

What is the recommended sampling rate according to the Nyquist-Shannon theorem for accurate sound reproduction?

Sampling rate = max frequency

Sampling rate ≤ max frequency

Sampling rate ≥ 2 × max frequency (correct)

Sampling rate < max frequency

What is the primary purpose of lossy audio compression techniques?

Remove imperceptible sounds and reduce bit rate (correct)

Maintain all original sound details

Enhance the accuracy of sound reproduction

Increase bit rate for better quality
