Rhodes Wah Wah

Today I was digging through my recording archives and came across a nice example of me running my Rhodes through a wah wah pedal with a little overdrive on it. So not being one to leave well enough alone, I sequenced the recording into a short phrase at 90 bpm.

I started by pitching a couple of the chords to create a progression, then added some delay and reverb to give it a nice cinematic ambiance. Perhaps I’ll build a track out it at some point. It reminds me of something from the soundtrack for the Fantastic Planet. By the way, the image is a photo of one of my Rhodes electric pianos. I own three of these very special instruments. Two of them I use for live performances, while the suitcase model in the photo stays put in my studio.

Door Stop

I always liked the sound this old spring door stop makes when accidentally kicked, but never recorded it until now. I think the fact that its attached to a one hundred two year old wooden door gives is some nice resonance.

This is a basic mono recording originally at 48kHz and 24bit. I plugged my favorite large diaphragm condenser into my M-Audio Firewire 410 with the phantom power enabled. I’m not sure what I might use it for. Perhaps it will make up some percussion in a future track.

Bit Reduction

This drum loop has been processed by reducing the bit depth and down-sampling the clip until very little of it is reminiscent of it’s original state. As you can see in the image, the waveform has been reduced to a wide pulse that sounds very distorted (you might want to start at low volume). The top of the image represents a short section of the original audio, while the bottom is the processed version.

The bit depth was reduced to two, which allows for four possible positions for the amplitude of the waveform. Two above zero and two below zero. There are no zero crossings that aren’t straight lines, therefore the output sounds very similar to audio that has been badly clipped, but in my ears this sort of distortion has more charm than just clipping the waveform. The only other processing involved is automated pitch shifting from down four octaves up to its original pitch by about seven seconds into the audio. Here is where it sounds closest to it original form. Its stays there until about nine seconds in and then shifts back down minus forty eight semi-tones until it ends after almost twenty seconds.

Tearing Grains

Using the simple granular synth packaged with Pluggo I created this nasty tearing sound. Towards the middle it sounds like it’s causing speaker damage, but don’t worry your speakers are safe. The original waveform was a sawtooth before the grain table algorithms manipulated it as you can see in the image.

Granular synthesis involves separating a waveform into grains that can be rearranged either randomly or with various formulas resulting in dense or scattered clouds of sound particles. For more information about granular synthesis, check out this entry on Wikipedia.

Three Story Buildings

How much processing can a voice recording take? I guess it depends on how badly you want to fuck it up. When it’s a recording of Donald Rumsfeld justifying the war on Iraq, I want to fuck it up as much as possible. That said, the recording is pitched and time expanded, run through a noise gate followed by a compressor, automated erosion, stereo delay (feedback at 80%, left at 5ms, right at 12.5ms, mix at 50%), and finally a reverb that creeps in with automated mix and decay. Enjoy!
