Usage

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

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).

Input parameters

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
