CULLING2004 - Binaural speech intelligibility

Usage:

[bmld_out] = culling2004(coherence,phase_target,phase_int,fc)

Input parameters:

coherence Maximum of the interaural cross-correlation, the value should be between 0 and 1.
phase_target Interaural phase difference of target signal, between 0 and \(2\pi\)
phase_int Interaural phase difference of the interfering source, between 0 and \(2\pi\)
fc Centre frequency of the frequency channel

Output parameters:

bmld_output improvement in predicted signal threshold when phase_target and phase_int differ compared to when they are the same.

Description:

culling2004(coherence,phase_target,phase_int,fc) calculates the binaural masking level difference for a signal in broadband noise. The input noise coherence and phase must be pre-calculated for the frequency channel bearing the signal. See jelfs2011 for an example on how to calculate these.
