First a confession:  My ear is generally not subtle enough to hear the difference between an analogue recording and a good digital recording.  Some people can do this, not me (on the other hand, I can taste Durian fruit and like it - so there you go).  So while I have no real preference between records and cds, I really don't like listening to MP3s that much and find that music from them often sounds ratty and muffled.  I have evidently found my audio tolerance level.

From NPR:

The Loudness Wars: Why Music Sounds Worse


Bob pointed to a YouTube video titled The Loudness War. The video uses Paul McCartney's 1989 song "Figure of Eight" as an example, comparing its original recording with what a modern engineer might do with it.

"It really no longer sounds like a snare drum with a very sharp attack," Ludwig says. "It sounds more like somebody padding on a piece of leather or something like that," Ludwig says. He's referring to the practice of using compressors to squash the music, making the quiet parts louder and the loud parts a little quieter, so it jumps out of your radio or iPod."


and Dr. Andrew Oxenham (of our fair University) explains it thus:

"Really, the challenge is to maintain the quality of a CD, but to stuff it into a much smaller space," Oxenham says. "Let's think about how digital recording works. You start out with a very smooth sound wave and we're trying to store that in digital form. So we're really trying to reproduce a smooth curve [with] these square blocks, which are the digital numbers [the 1s and 0s that are used to encode sound digitally].

"Now, the only way you can make square blocks look like a smooth curve is by using very, very small blocks so it ends up looking as if it's smooth. Now using lots and lots of blocks means lots of storage, so we end up using [fewer] bigger blocks. Which means we end up not representing that curve very smoothly at all."

"The difference between the smooth curve and the rough edges you end up with in the digital recording, you can think of as noise because that is perceived as noise," Oxenham says. "It's perceived as an error, something that wasn't there in the original recording. The trick is to take the noise -- which is the loss of fidelity -- and just make it so you can't hear it anymore."

"[The loud parts of the music are] giving the coding system a lot of leeway to code things not quite as accurately as it would have to," Oxenham says, "because the ear is being stimulated so much by the loud sound it won't pick up very small variations produced by the coding errors."

Thank you much.

Broadband in the U.S.A. (and territories)

From the broadband blog of the Federal Government:   

One of the challenges facing the Broadband Task Force is a question inspired by the 1989 classic film, "Field of Dreams": if we build it, will they come?  As John mentioned in his post, the 37% of Americans who have not adopted home broadband have a unique set of concerns, needs and barriers to overcome. Our two afternoon workshops on Wednesday, "Low adoption and utilization" and "Programmatic efforts to increase adoption and usage," addressed this topic.

MinnPost has a nifty breakdown of the issues at stake and a link to the RSS feed:

Though they're unlikely to win any branding awards for the snappy name "Blogband" (sounds like bunch of high-schoolers who launched their garage band to sing about blogging), the FCC has launched that blog in order to foster public dialogue about the National Broadband Plan (PDF), an initiative with just over 180 days before the FCC's deadline to send that plan to Congress.

So if you care about broadband (and issues like net neutrality), then  snagging this RSS feed and putting it in your news reader or just following the blog would be a good idea.


The Office of Information Technology (OIT) is pleased to announce that our University Technology Training Center (UTTC) courses, formerly offered for a fee, will now be available to current faculty, staff, and students at no charge.

Offering technology training is a part of OIT's effort to further the University's goal to become one of the top three research universities in the world. Professional development opportunities such as this can help to build skills and create efficiencies affecting academic and professional success and advancement for the individual and the University community as whole.
