Stimuli ratings for, from top to bottom, the anchor Null corresponding to the input signal without any process, the SBR baseline, the proposed models DDSP-mono-dec and DDSP-noise, and the reference ResNet model. Boxes correspond to the interquartile range (IQR) over all participants, with the mean indicated by an orange vertical line. Lower and upper whiskers are set to \(1.5 \times IQR\) below and above \(Q_1\) and \(Q_3\), respectively
