Device is a long whistle generated by the feedback that is automatically produced by a computer when you bring to the maximum level the input and output recording volumes of Quick Time Player and by physically, manually modulating the sound coming out of the computer speakers.

It is an insisted hiss, a painful one even, one that makes cats run away and dogs howl. It cuts the space horizontally, pushing towards the outside with a repulsive force and it seems to make the system strain, to emit a sound that is so high-pitched to be excessive.
A weird oppression crawls through the listener’s temples, scraping cavities in the cranial vault and getting impressed like an indelible sound memory.
