The following function reproduces figures that can be found in Georganti et al. (2013) [1].
You can download it from here.
The figures present the computed distance-dependent feature BSMD STD (Binaural Spectral Magnitude Difference Standard Deviation) for audio signals measured at different/receiver distances.
The BSMD STD may be derived from any dual-channel signal (binaural/stereo recordings). The BSMD STD feature is related to the standard deviation of the magnitude spectrum of Room Transfer Function, which is known to depend on the source/receiver distance. See [2] for more information.
