The Drones of Scarborough Superstore

I’ve mentioned the beautiful drone in the Loblaw Superstore before, but only last night did I actually get around to recording it:

  1. meats, fish – 2009/10/24 19:24:36
  2. chill – 2009/10/24 19:34:38
  3. ice cream – 2009/10/24 19:36:56
  4. organic dairy – 2009/10/24 19:40:52
  5. frozen veg – 2009/10/24 19:45:38
  6. ice cream 2 – 2009/10/24 19:52:04

You should probably listen through headphones or decent speakers – there’s some bass in there. If you can, try to experience it for yourself. The store is at 1775 Brimley Road, just south of the 401.

renaming files to include datestamp

My Marantz PMD-620 has a reliable internal clock, and stamps the files with the time that recording stopped. File times are remarkably fragile, so I wanted to make sure that the times were preserved in the file name. Perl’s rename utility does this rather well, as it allows you to use arbitrary code in a rename operation. So:

rename -n 'use POSIX qw(strftime); my $mtime=(stat($_))[9]; s/.WAV$//; $_ .= strftime("-%Y%m%d%H%M%S",localtime($mtime)); s/$/.WAV/;' *.WAV

which, for files 1007.WAV and 1008.WAV recorded last night, results in:

1007.WAV renamed as 1007-20091024192436.WAV
1008.WAV renamed as 1008-20091024193438.WAV

To actually rename the files, remove the -n from the command line. I left it in so you couldn’t blame me for b0rking up your files if you typed first, thought later.

There are probably smarter ways to handle the file extension. This works for me. Perfection comes later.

Save Chambers Harrap in Edinburgh

Harry writes:

As you may have heard, the historic dictionary firm of Chambers in
Edinburgh is threatened with closure by the parent company Hachette
Livre
.

They intend moving the English dictionaries to London and the
bilingual Harrap titles to Paris, involving not just the loss of 27
jobs in Edinburgh but the end of a publishing tradition going back
nearly two centuries.  Chambers is a Scottish and British institution
dear to the hearts of word-lovers.

Yes, the advent of free resources on the internet has changed the
world of reference publishing, but it is far from clear whether all
options for the future of Chambers Harrap have been properly
considered in what appears to be a very drastic and possibly even
underhand move by Hachette.  I feel strongly we shouldn’t just accept
this as inevitable.  Hachette should be forced at the very least to
undertake a properly full and open review of the situation first, in
due consultation with the NUJ.  If you wish to join with others in
urging them to think again, you may like to sign the online petition
at http://www.ipetitions.com/petition/chambers-in-edinburgh/.  It only
takes a few seconds.

she says I’m boring her camera

pentax mx + 40mm f/2.8 pancake

I missed my old Pentax MX. Of all of the cameras I’ve ever owned, it was probably the one with the most charm – and I don’t mean that in the same way that former Eastern bloc cameras were “charmingly” unreliable.

The MX doesn’t do much, but does all you need. It is tiny, but it’s a very solid chunk of metal. The shutter/mirror makes a very civilized little klipp! when fired. All the controls are where you’d expect them. The pancake 40mm lens gives my MX a snub-nosed appearance. I used to have the bigger and heavier 50mm f/1.4, which some lens nerds consider to be one of the finest lenses ever made.

Sure, it has its faults. The advance lever will poke you in the eye if you change shutter speed on the fly. And, well, y’know, film.

My Name is not Alvin

When I first heard of Alvin Lucier‘s “I Am Sitting in a Room” I thought it would be interesting to attempt a recreation with the tools I had on hand. Rather than shuffling tapes around, I recorded on my iPod Touch, and then e-mailed the file to my laptop to play back. I repeated this sixteen times. This is what I ended up with: my name is not alvin [mp3].

"My Name is not Alvin" recording rig

I’m pretty sure all I ended up recording was the hard drive and the backlight on my MacBook. By the final iteration, the cricket-like chirping is centred pretty close to 5400 and 16000 Hz.
