Phase Information & Hearing

Do our brains process phase information for slowly varying sounds or does it respond just to changes in amplitude and frequency?  Listen for yourself. (It will take a few moments for the sound to load.)  Verify that the waveform is changing shape significantly but the amplitude of the frequency components is unchanged.
