Making Sounds with Reverb
The third block of this composition used reverb VSTs to produce the sound material. It used the parameters of reverberation in order to ‘capture’ the reflections of sound, rather than keeping the direct sound source. The reverb settings were pushed to an extreme, creating strong artifacts which replaced the dry sound. The VST in use was Altiverb 7, which is based on physical impulse response convolution.
For this purpose, two main sources were chosen. This choice resulted from the theoretical discussion, mostly due to the need of finding a sound that had an interesting envelope for propagation. That is, a strong attack, a relatively long sustain and a smooth decay. In fact, inadvertently, the choice concerned a sound that is heavily dependent on its propagation. In other words, the common perception of this sound occurs more through its propagation in space rather than as a dry source. In that sense, it became quite difficult to erase the original source and use only the artifacts, because the artifacts were still as recognizable as the original sound.
