MAY2011 - Azimuthal localization of concurrent talkers
Usage
out = may2011(input,fs);
Input parameters
| input | binaural input signal [nSamples x 2 channels] |
| fs | sampling frequency in Hertz |
Output parameters
| out | localization structure |
Description
may2011 is a probabilistic localization model.
The out structure has the following fields:
| .param | processing parameters |
| .azFrames | frame-based azimuth estimate [Frames x 1] |
| .azimuth | time-frequency azimuth estimate [nFilter x nFrames] |
| .rangeAZ | azimuth grid [nAzDir x 1] |
| .prob | 3D probability map [nFilter x nFrames x nAzDir] |
| .loglik | 3D log-likelihood map [nFilter x nFrames x nAzDir] |
| .itd | interaural time difference [nFilter x nFrames] |
| .ild | interaural level difference [nFilter x nFrames] |
| .ic | interaural coherence [nFilter x nFrames] |
