Post Train Gravel Foot Stomp

As the sound of the freight train faded off into the distance and the railroad crossing bells came into view, I continued recording while deliberately walking on top of the large gravel that surrounded the train tracks. I particularly like the course crunching sound my footsteps made on the large gravel in contrast to the the softer sound of the finer gravel path leading away from the tracks. The wind screen helped but you can still hear some of it on the diaphragm giving the recording some lackluster, non-technical characteristics.

Sweeping the Front Walk

Here’s another recording made with the 3g iPod field recording kit I described in the last entry. This time I managed to get the device to record properly using the 96kHz sampling rate. I’m using the mic input on the iPod via the headphone jack, so the recordings are still in mono.

I held the Audio Technica AT822 with one hand as I swept cedar berries off of my front walk with the other. The cedar tree has produced hundreds of these fragrant berries this fall, so I need to sweep them away frequently to avoid litigation from the mail carriers.

Good Quality Field Recording on a Budget

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?

Time Stretched 60 Cycle Hum

To make this sound I increased the gain on some 60Hz buzz that I grabbed out of a bass guitar recording. There’s no bass, just the hum of electrical interference. A lot of boosting was necessary to get an adequate level.

Afterward I time stretched the waveform by varying amounts at consistent time intervals and manged to create this rhythmic pattern. A touch of chorus gave it some stereo spread and a short delay put it into space.

Cover Your Eyes

A lack of galactic space time has forced me to go backwards for the One Sound Every Day project, but I hope you’ll enjoy this track from Keston and Westdal’s latest release, One Day to Save All Life. Cover Your Eyes started out as a loop of sustained Rhodes notes that I had dropped into Ableton Live during a rehearsal for a show. If I remember correctly, we ended up performing the piece the same night that we created it. I love the samples Nils added that are destroyed with processing creating some complex and swirling textures throughout the piece.

Reverberated Graintable Noise

I produced this sound by programming a scale in a MIDI clip and then sending it to a virtual instrument designed to allow for freely manipulating granular synthesis through several seven point envelopes. I made several takes while I adjusted the envelops and other parameters.

One warning, this take has some piercingly high frequencies in a few places. The sound reminds me of some sort of scrambled futuristic alarm system. This led me to adding a warehouse reverb to the mix to put in into sci-fi thriller territory.

Random Parameter Keyboard Mash

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.

Dark Chorused Guitar

I am not, nor will I ever claim to be a guitarist, so please forgive the playing in this example. I do like the sound I have achieved here though. To get it I ran a cheap Fender Squire through VST distortion, thickly modulated chorus, followed by delay, and reverb. It’s very 80s, although I was not necessarily going for that. I does seem to go well in the piece in which it was recorded.

Acceptable Use of Factory Presets and Samples?

An issue that I often contemplate is, when is it acceptable to use factory presets and samples? I tend not to use them most of the time in favor of inventing new sounds and sampling from my own recordings and instruments. However, sometimes I make exceptions, such as using presets for classic keyboard sounds like pianos and organs, or individual drum samples for programming beats. Personally I have an aversion to using them, but I don’t doubt that lots of excellent music is produced using unchanged samples and factory presets. So the question remains, when is it a good idea and when is it a bad idea to rely on what has been painstakingly produced for us by industry professionals?

When I use presets I usually make some adjustments to in order to get closer to what I’m after sonically. In the piece Rihaku that I wrote with Nils Westdal for our album Truth is Stranger I used the factory sampled piano on the Yamaha A3000. I would have preferred to use an acoustic piano, but opted to give the sampler a go for budgetary reasons. In order to get a bit more sustain out of the sound I made some subtle but effective changes to the patch including manipulating the envelope, adjusting the velocity sensitivity, and slightly compressing the output.

Korg MS2000 Tempo Delay Effects

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.
