***!!! You must disable audio enhancement before listening !!!***
On windows "disable all enhancements" for all devices, on mac disable "sound enhancer", on mobile make sure you aren't using mono audio, and if you have a control panel for your headphones make sure to disable any and all similar stuff ("enhancements", "auto leveling", etc)! Noise canceling headphones might also mess with the effects! "Simulated surround sound" headphones, etc. -- all these things may affect the "truth" of what you're hearing.

This series presents a variety of fascinating psychoacoustic phenomena and illusions.
We will cover 42 of them, with examples and explanations along the way. See if they work on you!
