The soundscape created by algorithmically synthesising the map data has not been altered apart from some equalising of volume levels, although acoustic choices were made as the maps ‘sounded’ more interesting as white lines on black rather than black lines on white. Both the TriAtlas map images and their sound visualisations are projected onto 360 degree dome mirrors, reflecting the disorienting spatial and navigational perspectives of stargazing. The star maps re-emerge during this process with some ‘glitching’ of pixels and a slightly altered linear spectrogram perspective. Then VoceVista (Sygyt Software) synthesises this sound back into sonic visualisations. Sonic Photo (based on Photosounder) has been used to scan the relevant TriAtlas star map pixels and synthesise them into sound. Two different sound programs have been used to analyse Mayer’s double star mappings. The current positions of Mayer’s double stars have been located on 12th magnitude TriAtlas star maps through J.S Schlimmer’s re-calculations in the Journal of Star Observations (Schlimmer, 2007). It is a good deal more expensive than other plug-ins in its category, but the extra cost is justifiable given its versatility and range of features. 'Doppelstern Soundings' investigates alternative sonic mappings of Christian Mayer’s double star observations in Mannheim during 1776-77. NuGen Visualizer is a powerful and attractive-looking spectrum analyzer plug-in that can handle a multitude of audio-related tasks.
