Cognitive Daily is carrying out an online poll to determine just how audible the fluctuation in quality is between mp3′s that have different encodings:
I created three different versions of two song clips — 64, 128, and 256 kbps MP3 format. Then I re-encoded all of them at 256 kbps so the files are all the same size. Can you identify which recording sounds better? Is there a difference between the listening skills of “audiophiles” and ordinary listeners? Now we’ll find out.
There have been numerous mp3-vs-lossless debates here and elsewhere, so I’m quite curious to see the results of this test. To participate, keep your ears and headset at the ready and click here. The results should be posted at Cognitive Daily next Friday, November 30.
