Frequency Shift explores the limits and sensitivities of perception from a beyond-human perspective. Through a series of interlinked frequency shifts in both the audible and visible domains, windows are created to explore a world we would not have access to under normal circumstances – a world tailored to the delicate and perplexing senses of the bat. Two questions arise – what do you see through the eyes of a bat? What do you hear through its ears?

The visual aspect of the work consists of two fine art prints (100 by 70 cm) and are an interpretation of what it would be like to see through the eyes of a bat. Starting from lidar scans, a process of down- and upsampling was used to simulate the low light and colour sensitivity of a bats eyes. Then, a shift in frequency was applied to adjust our human eyes to the two windows into the world of the bat.

Bats can, similar to sonar, locate objects using reflected sound, this is called echolocation. As echolocation is a way of perceiving we as humans cannot dare to imagine, the audio portion of the work aims to change the perspective on listening with an audio installation. By placing a device on the head, the listener listens through their head rather than their ears. The composition itself (30 minutes, loop) contains field recordings, shifted in frequency, transforming the world around us, tuned to the ears of a bat.
