128 or 320 kbps – can you hear the difference?March 11, 2009
Okay, we are going to do a quasi-scientific study here with the z=z community, to see if people can hear the difference between 128 kbps and 320 kbps audio streams. Go to mp3 or not, listen to the two sound samples, decide—or guess—which one is at the higher bitrate, and then post your results in the comments, along with any ancillary information (like whether you used speakers or headphones). I couldn’t tell the two samples apart, at least not on my laptop speakers, but I had a 50-50 shot at getting it right, and I did. Let’s see if we can get enough numbers to exclude (or confirm) randomness.
UPDATE (Friday, 10:23 am PDT): We are up to 6 people who got it right and 5 people who got it wrong. I’d love to get some more datapoints. Please share this link and ask people to comment or to send me an e-mail or a tweet.
UPDATE (Friday, 10:49 am PDT): A poll! This is much easier. If you’ve already responded in the comments, please do not vote in the poll.
