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]
