Examples wanted - OK. This is my favourite example. The two signals below have identical power spectrum (and rms level).
They differ in phase.
However, for an experienced listener it is easy to tell the sound difference:
The files available for testing are attached below in the in_out_phase.zip file. The 2nd zip file contains both files under test in a row in just one file. The change of perceived pitch can be heard when 1st file transits to the 2nd one, though both signals have the same amplitude spectrum and differ only in phase of the 3rd harmonic component.
