This guy sets up on the SE corner of Yonge & St Clair most afternoons, and plays endless variations on the above recording. He’s playing an autoharp with the chord bars removed, and run through a homebrew battery-powered amplifier with much reverb and distortion. A bunch of the burbly noises are 8kbit/s voice recorder artifacts from my phone.
Although the themes seem repetitive, I don’t think they repeat exactly every time. He seems to be in a happy place playing them.
If you go to the Incompetech Multi-Color Graph Paper PDF Generator and set the grid spacing to 0.4, 0.8 and 4 lines/cm, you get a nifty HP-GL unit grid with major lines at 1000 units (25 mm), intermediate lines at 500 units (12½ mm) and minor lines at 100 units (2½ mm):
By a very roundabout route, I used GDAL’s simplify function to half the line count of my hypotrochoid plots with little visible degradation. The optimised page took far less time to plot:
Next time, I’d definitely use Shapely instead of messing about with GIS formats. Who knows, I might even integrate it into Chiplotle. Eventually. (Update: though I have some code that does something …)
Plotters are resolutely electromechanical devices. They turn digital command into analogue output, but my one never sounds too happy doing it. It grumbles, sighs and even moos as it plots. A recent plot sounded a bit like this: .
The Raspberry Pi’s hardware and software support has come a long way in the few months it has been in the wild. I first tried this application in the summer, and the results were dismal. Now, thanks much improved USB driver support under Raspbian, I’m pleased to say it works flawlessly.
Earlier this year, I bought a turntable (ack!) for transferring vinyl to mp3. I have a TC-772 USB phono preamp, which spits out a 48 kHz stereo audio stream. If you plug the USB output of the preamp into a Rapberry Pi (running Raspbian Wheezy with all the updates), it’s instantly recognized as an audio device:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp.
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001 Device 004: ID 08bb:2902 Texas Instruments Japan PCM2902 Audio Codec
If you install the ALSA recording utilities (sudo apt-get install alsa-utils pulseaudio – this should pull in a whole bunch of necessary packages), you can record directly from this device with the following command:
which records from the ‘pulse’ audio device, displaying a stereo text VU meter (handy for setting levels), writing to a two channel 16-bit 48 kHz file called ‘out.wav’ for a maximum of 900 seconds (15 minutes). arecord has a baffling number of recording source options; arecord -L will show them. ‘pulse’ was the first one I tried.
That’s the rapid clatter of chopping up Kothu Roti at Amma at the end of our street. You know that tasty spicy food is imminent when you hear that sound. I’m really pleased that Amma’s back under the original management. The other proprietors just didn’t care as much about their food.
Very little urban hum this morning (holiday), and the air conditioners really hadn’t started yet, so please be amused by the sounds of the garden (featuring mostly mockingbird): about quarter to nine. It does a passable seagull and also a red-tailed hawk. The vehicle reversing sound, though, is real.
I’m either getting old or conventional, ‘cos I bought something I said I would never have enough time or space for: a turntable. I won’t forsake my beloved MP3s, but there are somethings you just can’t get electronically. One of them being the 1981 Stampfel & Weber album “Going Nowhere Fast”, which I snagged from Etsy from a west coast seller.
I bought an elderly Technics from Ring Audio, and set it up with a USB phono preamp from Phonopreamps.com. It sounds good, I guess. It certainly sounds different from MP3s, but better …? Dunno. My two cynical theories hypotheses of vinyl snobbery are:
The more you have invested in your system, the more confirmation bias tells you it sounds better.
Vinyl is the record industry’s last-gasp attempt attempt at relevancy, because you can’t home-cut your own discs. As there’s always analogue loss in ripping from vinyl, it’s self-policed rights management by the sound quality snobs. Imagine that: DRM conditioned into the listeners themselves!
I have not got a lot of records:
Going Nowhere Fast — Stampfel & Weber
The Holy Modal Rounders
The Holy Modal Rounders 2 (are you sensing a pattern here?)
The Television Tells Us / Freeing Song by Reindeer — The Music Tapes (Julian sent me this in 1998, and I think this is the first time I’ve played it. For a few days, it was the only record I had, and it was merciful that Catherine was away, as she only has a normal human tolerance for this sort of thing)
Ghetto Kitty Island Split 7″ – featuring Chicken on a Raft, Of Montreal, Bart Davenport and The Minders.
Speaking of which, I understand that the latter EP is not exactly widely known, is totes OOP, and completists might dig Of Montreal‘s ”Epistle to a Pathological Creep (demo)”, so here it is ripped for your listening pleasure:
I recorded it with arecord, and edited it with Audacity. The arecord command line (more for my reference than your interest) was:
I do a lot of conference calls. Usually there’s a tone and the participant’s name played when they sign out. If it’s a big call and everyone leaves at the end, this signout cascade gets quite lengthy. Here’s part of one I recently caught: signout cascade.
