When we were at the Cards/Padres game over Opening Weekend, I decided it would be a cool idea to record some of the ambient noise just using the memo feature on my iPhone.

I had completely forgotten about this until just this morning—and when I checked, I realized that I’d recorded a Pujols home run (his first of this year, actually) and the crowd reaction to it. If you listen very carefully, you can hear the ball jump off the bat.

The fireworks going off made Caleb collapse against my shoulder and cover his ears. I don’t think he had any idea what was going on, but he’s said that he’s happy to go to another game so long as there are no fireworks there. (We were also in Left Field Terrace seats for the game, so we were pretty close to the noise.)

Barnes and Noble just opened a digital audiobook store. From Publisher’s Weekly:

Barnes & Noble has taken another step in deepening its role in the digital marketplace, launching its Audiobook MP3 Store on Barnes & Noble.com. The store will feature spokenword audiobook MP3s available for download and transfer to iPods, iPhones, MP3 players and other portable devices. The site is launching with more than 10,000 titles across all genres, priced between $10 and $20 per download.

“As the use of MP3 players, iPods, iPhones and other digital devices continues to increase, it is important for Barnes & Noble to continue to expand our audio selections,” said Tom Burke, executive v-p, E-Commerce Barnes & Noble. Overdrive is managing the distribution of titles through the BN.com site. Later this year, B&N is expected to launch an e-bookstore, following its acquisition earlier this year of Fictionwise.

And it’s all DRM-free.

I wonder what that new e-bookstore is going to look like.
