Dear Alexander:

There are occasions when the phase can affect the timbre (and the =
pitch too) when the harmonics are close together, so that they are =
not resolved at the cochlea. Then the envelope shape (as perceived =
at the hair cells) will depend on the phase (given 3 or more =
harmonics).=20
