Transformation – Westring22

Collaborative Installation

TRANSFORMATION underscores and thematizes the transition of the Westring 22 building from one phase of its existence to the next. Like the city of Bochum, the building itself is in transition. This change, however, is not meant to go unnoticed, but to be illuminated and clarified. The participative audio-visual installation TRANSFORMATION allows visitors to become part of this transformation.

I am Sitting in a Room - Resampled

Composition

I Am Sitting in a Room – Resampled I and II are versions of the piece I Am Sitting in a Room by Alvin Lucier in the digital domain. They feature the Elektron Octatrack Mk 1 resampling itself internally for one hour in two different setups. Listening through headphones recommended.

The initial sample is the first sentence that Alvin Lucier is speaking in the original piece. In I Am Sitting in a Room – Resampled I, this sample is played back by an audio track of the Octatrack and recorded internally by a second track at the same time. Then this recording is played back from the second track and captured again by the recorder of the first track. This process repeats for 60 minutes. The initial sample was recorded with the Octatrack at 44.1 kHz 24 Bit Stereo from an external line level source. Internal resampling at 44.1 kHz 24 Bit Stereo, no time stretching applied, no filtering, no signal processing. The initial sample starts and ends at a zero crossing. Recorded from the main outputs of the Octatrack in 48 kHz 24 Bit Stereo. The video was created with ffmpeg showing vectorscope, spectrogram and waveform of the recording.

In I Am Sitting in a Room – Resampled II, the initial sample is played back by an audio track of the Octatrack and sent to the analog output. Then the input capturing that signal is recorded by a second track at the same time. Then this recording is played back from the second track and captured again by the recorder of the first track in the same way. This process repeats for 30 minutes. The initial sample was recorded with the Octatrack at 44.1 kHz 24 Bit Stereo from an external line level source. External resampling at 44.1 kHz 24 Bit Stereo, no time stretching applied, no filtering, no signal processing. The initial sample starts and ends at a zero crossing. Recorded from the main outputs of the Octatrack in 48 kHz 24 Bit Stereo. The video was created with ffmpeg showing vectorscope, spectrogram and waveform of the recording.


One Sample OSC

VST FX Plugin

One Sample OSC is a VST Plugin and Pure Data (Vanilla) abstraction, available in two different versions.

Processing a stereo audio input signal on a one sample accurate level. The input audio signal is read out sample by sample. It is possible to interfere with the speed or timing, at which those samples are written consecutively into wavetables of two oscillators for instant playback at a given frequency.

The unusual and non-accurate timing caused by this kind of signal processing results in a great variety of sounds. Due to the sample accurate processing, the output signal is always related to (and depending on) the audio input signal. Feel free to experiment with different settings and don’t forget to especially explore extreme small and large values.

Delaylay

VST Delay Plugin

Delaylay is a wonderful weird free and open source delay VST Plugin. It features a lot of different delay modes: From Karplus-Strong like synthesis to DAW tempo synced delay lines, everything is mapped to one single controller.
Delaylay works in four different modes from simple stereo to spread, detuned, down-pitched and half-timed stereo delay with ping pong effect applied.
Delaylay interpolates smoothly between different delay times, depending on the last delay time set.
