It's just a Phase, mom

I guess you've watched my video about Phase. If you didn't, it's 15 minutes well spent:

If you want to take the survey, scroll down to the bottom of this page. Else, have fun with some audio samples with weird phases ^_^

Random phase swaps

You can hear 15 notes, all at 220Hz. Some of them have a flipped phase.

220 Hz, random swaps

Phase drift sweeps

The next samples sweep the phase on the right ear from 0° to 180° and back to 0°. The left ear's phase is always at 180°. I made samples for different pitches (care: high pitches can be pretty annoying — keep your volume low, and turn it up only when you feel comfortable).

Phase-flip pairs

Now a few samples where you hear 4 notes. Notes 1 and 3 are identical and share the same phase, while notes 2 and 4 are identical but have a flipped phase, either 180° or 90°.
