AB  - Inspired by the recent discovery of two speeds of sound in the atmosphere of Mars, this article presents a real-time Digital Audio Effect (DAFX) implemented as a Virtual Studio Technology (VST) plugin. Our purpose is to simulate how a frequency-dependent speed transforms sound at different distances and to assess the degradation in speech intelligibility produced by such transformations. It was found that, at close distances, linear spectral changes could produce the largest intelligibility degradation, whereas, at long distances, degradation was similar to that introduced by other types of changes (logarithmic, sigmoid, or stepwise). The resulting plugin is not necessarily accurate, but can be used for expressive and illustrative purposes.
