Figure 1. Acoustic features.
Graph showing values of timbral (Brightness, RMS Energy and Roughness), rhythmic (Pulse Clarity) and tonal (Key Clarity) features of MusiCure and Noise extracted with MIRToolbox. MusiCure resulted to have comparable loudness than the Noise stimulus, but to be less bright, rougher and contain clearer tonal centers and pulse, as revealed by the mean parameters of Brightness, RMS, Key Clarity and Pulse Clarity, respectively.
