The answer is really simple actually &#8230;<\/em><!--more--><\/p>\n<p>First &#8211; you&#8217;re right. Whatever you think you recognized &#8211; &#8220;Laurel&#8221; or &#8220;Yanni&#8221; .. you&#8217;re both correct. Is that possible? It sure is. Let me show you ..<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-2380 size-full\" src=\"https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/laurel.jpg\" alt=\"\" width=\"433\" height=\"291\" srcset=\"https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/laurel.jpg 433w, https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/laurel-300x202.jpg 300w\" sizes=\"auto, (max-width: 433px) 100vw, 433px\" \/><\/p>\n<p>This is what &#8220;Laurel&#8221; looks like. Before you click to listen &#8211; make sure you have real loudspeakers or high quality headphones. Because if you don&#8217;t, if you listen to it on your phone or if you are otherwise technologically challenged, you may not be able to hear &#8220;Laurel&#8221;. I ran in on our sound environment and everybody here &#8211; without any doubt &#8211; recognized it as &#8220;Laurel&#8221;. Try yourself:<\/p>\n<audio class=\"wp-audio-shortcode\" id=\"audio-2378-1\" preload=\"none\" style=\"width: 100%;\" controls=\"controls\"><source type=\"audio\/mpeg\" src=\"https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/laurel_yanni.mp3?_=1\" \/><a href=\"https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/laurel_yanni.mp3\">https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/laurel_yanni.mp3<\/a><\/audio>\n<p>&nbsp;<\/p>\n<p>If you are not hearing &#8220;Laurel&#8221; &#8211; you either have a bad audio environment, you can&#8217;t recognize low(er) frequencies or your brain is wired to &#8220;click&#8221; in to the higher frequency spectrum. Because in order to make &#8220;Yanni&#8221; from &#8220;Laurel&#8221;, we have to do a little equalizer magic.<\/p>\n<p>This is the the curve of equalization necessary to convert &#8220;Laurel&#8221; to &#8220;Yanni&#8221;:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-2382 size-medium\" src=\"https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/yannieq-300x125.jpg\" alt=\"\" width=\"300\" height=\"125\" srcset=\"https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/yannieq-300x125.jpg 300w, https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/yannieq-500x208.jpg 500w, https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/yannieq-768x319.jpg 768w, https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/yannieq-600x249.jpg 600w, https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/yannieq.jpg 809w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>We reduced everything below 3Khz and amplified everything above 3Khz. This results in the following digital representation.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-2383 size-full\" src=\"https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/yanni.jpg\" alt=\"\" width=\"515\" height=\"288\" srcset=\"https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/yanni.jpg 515w, https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/yanni-500x280.jpg 500w, https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/yanni-300x168.jpg 300w\" sizes=\"auto, (max-width: 515px) 100vw, 515px\" \/><\/p>\n<p>Looks almost the same, but not quite. According to linguists, both &#8220;Laurel&#8221; and &#8220;Yanni&#8221; have the same vocal prints or patterns &#8211; so we aren&#8217;t able to tell &#8220;Yanni&#8221; from &#8220;Laurel&#8221; by looking at the wave form. However &#8211; by looking at the spectrogram, we clearly see where &#8220;Laurel&#8221; and &#8220;Yanni&#8221; are hiding:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-2384\" src=\"https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/laurelspec.jpg\" alt=\"\" width=\"474\" height=\"273\" srcset=\"https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/laurelspec.jpg 474w, https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/laurelspec-300x173.jpg 300w\" sizes=\"auto, (max-width: 474px) 100vw, 474px\" \/>In other words: If your technology doesn&#8217;t reproduce the lower frequencies (correctly) or if your brain favors higher frequencies, you are more likely to hear &#8220;Yanni&#8221;. But now &#8211; without further delay, let&#8217;s get &#8220;Yanni&#8221; out of the bottle. At least for those of us who need the help.<\/p>\n<p>Unfortunately, because of modern compression technologies, it&#8217;s not that easy to get this file to play in a web-browser. You may have to crank up the volume. But here you go ..<\/p>\n<audio class=\"wp-audio-shortcode\" id=\"audio-2378-2\" preload=\"none\" style=\"width: 100%;\" controls=\"controls\"><source type=\"audio\/mpeg\" src=\"https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/yanni2.mp3?_=2\" \/><a href=\"https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/yanni2.mp3\">https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/yanni2.mp3<\/a><\/audio>\n<p>&nbsp;<\/p>\n<p>Because the mp3 audio representation is not good, here are both audios as WAV files to play around on your own.<\/p>\n<p><a href=\"https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/laurel_yanni.wav\">laurel_yanni<\/a><\/p>\n<p><a href=\"https:\/\/www.rollofone.com\/wp-content\/uploads\/2018\/05\/yanni2.wav\">yanni2<\/a><\/p>\n<p>Finally &#8211; there have been media reports that &#8220;Alexa&#8221; or &#8220;Google Home&#8221; devices may react to certain sounds unnoticeable by &#8220;normal&#8221; human ears.
