# sig_breebaart2001 - computes the signals for the breebaart2001 experiment

## Usage

signalout = sig_breebaart2001(inttype,fc,sl,sdur,sphase,nbw,nl,ndur,nphase,hannramp,fs)


## Input parameters

 inttyp 'target' or 'reference' defines the interval type fc center frequency sl overall signal level sl duration of the signal sphase interaural phase difference of signal nbw bandwidth of the noise nl overall noise level ndur duration of the noise nphase interaural phase difference of noise hannramp duration of the hanning ramps fs sampling frequency

## Output parameters

 signalout the generated experimental signal which can be feeded directly into the model

## Description

The following parameters for 'nphase' are possible:
'nphase' = 0 no phase difference, correlation = 1; 'nphase' = pi masker interaurally phase reversed, correlation = -1; 0 < 'nphase' < 1 defines interaural correlation

signalout = sig_breebaart2001(inttype,fc,sl,sdur,sphase,nbw,nl,ndur,nphase,hannramp,fs) generates the signals for the breebaart2001 experiment where sinusoidal signals are masked by noise. 'inttyp' determines if it is a target interval (signal + noise) or just a reference interval (noise only). The sinusoidal has a center frequency of 'fc' (in Hz), an overall level of 'sl' (in dB SPL), a duration of 'sdur' (in seconds) and an interaural phase difference of 'sphase' (in rad). The masker is generated at a center frequency 'fc' in Hz, with a bandwidth of nbw (in Hz), duration ndur (in sec), overall level nl (in dB SPL) and an interaural phase difference of 'nphase'. Both signal and masker are gated with hanning ramps with a duration of 'hannramp' (in s). The sampling rate is defined with fs (in Hz).
