Re: SV: [AUDITORY] auditory illusion

[Alexandre Lehmann <alexandre.lehmann@xxxxxxxxx>]

Dear list, Al and Guy,

A mathematician called Vincent Feuvrier has created a software (source code is also provided) to create infinite rising pitch and speed sounds. You might be interested for educational purposes.

Infinite acceleration

Infinitie rising

Dear list and Al,

 

sound examples of the illusion are found under the heading “Supporting information” at about ¾ down the article page (http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0008151). You can easily find it by clicking “Supporting information” in the blue box at the top of the page ( “Jump to”) or perhaps this URL will take you directly there: http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0008151#s4

 

 

Cheers

Dear list and Leon,

I have fooled around in the past with sequences that seem to speed up or slow down indefinitely.  I was interested to read about the sequence created by Guy Madison, cited by Leon. But I couldn't find an audio demo associated with the article, although I would have liked to hear it.
