Are we starting to prefer MP3s?

March 17, 2009

ipodnano1According to Stanford University music professor Jonathan Berger, the number of people who prefer MP3s to higher fidelity formats is rising every year. Every fall, he asks his incoming students to listen to music in a variety of formats and rate which ones they prefer. Apparently, there is a steadily-increasing fraction of students who actually prefer the overly-compressed sounds of low-bitrate MP3s, at least for rock music. (I say ‘apparently’ because a quick search in Google Scholar failed to turn up published data – if you can find it, let me know.) This reminds me of the debate about what tastes better, tap water or spring water. The Ontario Science Centre had an exhibit that showed that your preference just depended on what you normally drank. It looks like MP3s are the same way – people prefer what they are used to, even if other formats are objectively better.

Predictably, audiophiles are freaking out. However, as the price of storage and bandwidth drops, there’s no reason to think that higher fidelity formats won’t become the norm. I’m sure there were lots of people who preferred the sound of cassette tapes, or AM radio.

Interested in whether you prefer 192 or 320 kbps MP3s? Check out an earlier z=z post here.

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.
