Software

A Matlab implementation of the efficient monaural and binaural audio quality model eMoBi-Q (Eurich et al., 2024) can be found here.

A Matlab implementation of binaural auditory model described in Biberger and Ewert (2022) the can be found here.

Data and stimuli resulting from Biberger and Ewert (2022), where binaural detection thresholds and audio quality of speech and music signals in complex acoustic environment were examined, can be found here.

A Matlab implementation of the combined monaural and binaural audio quality model as described in Fleßner et al. (2019) can be found here. It combines the outputs of a monaural and a binaural audio quality model, namely GPSM^q (Biberger et al., 2018) and BAM-Q (Fleßner et al., 2017).

A Matlab implementation of the monaural audio quality model GPSM^q as described in Biberger et al. (2018) can be found here. 

A Matlab implementation of the binaural audio quality BAM-Q as described in Fleßner et al. (2017) can be found here.
