A small project, to measure the visual bias when judging tritones.
The "tritone" consists of 2 distinct shepard tones with half an octave tone difference, played successively.
Every human has it's own way of perception: One would say after hearing the C-F# tritone, that the F# is clearly higher-pitched than the C, but another person would judge the C as the higher tone.
We tried to measure, if there is a possibility of manipulating the perception by adding a visual stimulus by using this program coded in C++.
Our outcomes are, that it is possible to manipulate the perceptions of the individuals significantly by a visual stimulus.
If you're interested in retesting our outcomes, feel free to download, use and edit this program by your own needs.
The code is quick and dirty but I will clear it up, as soon I have the time.
