If you want to have a cat wailing at least make it wail at all the frequencies to give some type of consistency. Take imagine and change the frequency to the different levels and try it again. BTW I listened to your test and because you switched tunes for just about every test it made no sense. Here is an example video: Assuming John Lennon has been resurrected, I presume they used a pitch shifter! The Beatles tuned to Hz naturally. This has a clear effect on the sound of the instrument which is not the same as artificially altering the tuning of recording originally made at normal pitch tuned to E.īut what people are doing on YouTube is exactly the same process as I did. Take, for example, the electric guitar - several very eminent players were renowned for tuning down a semi-tone to E flat. I then took the songs nearest to the centre of each cluster which had a license that allowed me to use it in the experiment. I used a k-means algorithm on the arousal and valence score. I wonder if the result might have been different for those with absolute pitch? The data from the experiment can be downloaded from here. I suspect that pitch shifting to higher frequency makes thing worse because of artefacts introduced by the pitch shifting plug-in I used. Pitch shifting the music to a lower pitch did not make any difference to preference. Changing the frequency has a significant effect. A higher mean score shows a frequency that was liked more. That is a couple of hundred people doing the test. So far people have listened to pairs of clips, where for each the listener simply says which one they preferred.
