EXP_GEORGANTI2013 - Figures from Georganti et al. (2013)

Usage

exp_georganti2013(flag);

exp_georganti2013(flags) reproduces figures from Georganti et al. (2013).

The following flags can be specified;

'fig9' distance estimation for a small room
'fig10' distance estimation for a large room

The figures show 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 is related to the standard deviation of the magnitude spectrum of room impulse response, which is known to depend on the source/receiver distance. See Georganti et al. (2013) for more information on applications.

Examples:

To display Fig. 9 use

exp_georganti2013('fig9');
exp_georganti2013_1_1.png

To display Fig. 10 use

exp_georganti2013('fig10');
