STRAUSS - A Tool to Sonify the Universe
To create sonfications, we primarily utilise our new code Sonification Tools and Resources for Analysis Using Sound Synthesis (STRAUSS). This is an open source code and we welcome new users and contributors. An article introducing STRAUSS and its functionality appears in ICAD 2023 (Trayford et al. 2023a).
Briefly, this python code allows the user to synthesise sounds or manipulate pre-recorded audio samples with properties (e.g. pitch, volume, timbre) that are mapped from input data. You can also move objects in artificial space around an ‘observer’ and the code will correctly calculate the relative volumes for the different channels of different speaker setups (e.g. stereo, 5.1 systems or ambisonics). For example we used this to assign a sound to the Moon and the planets and then create the illusion, through sound, that they orbit around the audience. Additionally, we added a volume envelope to emphasise this orbiting effect.
