Alguém já ouviu falar disso? Ilusão
de áudio?
E a coisa é a mais insana e inacreditável possível!
Pressione
play uma vez. Ao terminar, pressione de novo e de novo.
E fique "bolado".
Louco!

Que doido!
Músicos do CC, como se explica essa afinação?
Just like there are optical illusions, there is also “audio illusion” or “acoustical illusion”. This one is called Shepard Tone. When a number of octave notes are played at the same time, the average human ear will simply hear the one note, closest to the last pitched sound it heard, as opposed to differentiating and splitting that sound into its singular octave parts. The volume of the higher pitched tone slightly decreases and the lower pitched one increases over the scale, which is what makes the effect seem so seamless.
