PROCESS : Creating the Sound

  1. After exporting the image file under a .tiff extension, opening it as Raw Data in Audacity

2. The sound appears as a highly saturated bloc (green to red bar indicating the level of saturation) of glitch sounds

3. Applying Reverberation Effects to it (multiple layers) to smooth the sound. The settings below aim to have a “small room reverberation” (less loss of low sounds), and is set to boost the effect on low tones rather than higher ones. Also the attenuation setting helps with having a less agressive sound and something closer to melodic layers.

4. The result is much less saturated but still reaches peaks, and embodies many parasite noises.

5. Applying a “Low Pass Filter” allows to isolate all frequencies in a certain range. Here, the frequencies are cut around 200Hz (right before entering the “mid” range which is, in music, often the melody). The Low Pass Filter includes a boost of the 30 – 100Hz frequencies, which correspond to sub-bass, the more “physical” impact of bass.

6. The red parts indicate saturation peaks, so I have to apply a “Limiter Filter” which will prevent the sound from saturating, yet preserving its tonality.

7. Final Result.

8. Mixing this work with extracts of previous prototypes (focusing on higher frequencies) we obtain a result taken from that low, sub bass and other more melodic variations, appearing and disappearing through the soundscape.
