Table 1: Sound examples for the particle trajectory sonification model

• Single Particle in a single data point potential function phi(r): S1 (mp3)
• Set of 50 particles in the potential function for a 2D dataset with one cluster: S2 (mp3) --- and with three clusters: S3 (mp3)
• Sequence of particle trajectory sonifications, systematically decreasing the bandwidth sigma, starting with large values, where V contains only one trough at the mean of all data, ending with sigma so small that all data point potential functions are well separated. Listen to the examples for a dataset with a gaussian distribution of data points: S4 (mp3) and with a mixture of 3 gaussian distributions with different mean and covariance S5 (mp3)
