I made this recording of a freight train near downtown Minneapolis today using an old third generation 20 gig iPod running Linux (more info at ipodlinux.org). The microphone I used to capture the sound was an Audio Technica AT822 stereo condenser, list price of $419, but zZounds.com has them for about $250. The nice thing about the AT822 is that it comes with an XLR to 1/8″ stereo cable as well as a standard “Y” cable. This makes it easy to plug it into a hand held portable recording device like a DAT recorder or MiniDisc.
Unfortunately the iPod only records in mono via the headphone jack, but I was able to get a good strong signal into it via the left channel element, and record at a staggering 88.2kHz sampling rate! 96kHz is also supported. There is a way to get a stereo line level signal recorded through the dock connector, but I would need a preamp between the iPod and the mic so I may not bother unless I find something cheap, tiny and battery operated. I’ve ordered a replacement battery for the iPod, and I’m planning on keeping this small kit in my bike bag to make impromptu recordings. I would be interested in hearing about other examples of good quality field recording ACB readers have used. Anyone else have similar techniques?

With very little time for today’s sound I resorted to randomizing the parameters in Pluggo’s xmod synth, then resampling the results as I dragged the mouse up and down on the virtual keyboard in Ableton Live’s sequencer. I often use this technique with a variety of VSTs as a starting point to get a new sound, so I thought I’d lay it down, so you can hear a little behind-the-scenes audio.
I created this synthesized effect using a Korg MS200 Analog Modeling Synthesizer. I often use this instrument with the external sync enabled for arpeggiation and and tempo delay processing. The delay does some strange things with the external sync enabled. As you adjust the delay time it jumps from different units of time within the tempo including triplets. This can produced some future dub, spaced out, synthethized effects when the feedback is up all the way.

Last Friday I posted sounds created by rowers on the Mississippi river. Sadly, weak batteries prevented me from capturing much more, but I gave them a rest and had another go a bit later in the evening. This time my aim was to record the sound of the fire crackling. I wasn’t bothered about the general ambiance of the site, or the noise my mates were making as I made the recording.
