SIG_HARTMANN1996 - - Stimulus from Hartmann and Wittenberg (1996)

Usage:

sig = sig_hartmann1996(nprime,f0,Obj,azi,dur,condition)

`nprime`	Highest altered harmonic. Default is 0.
`f0`	Fundamental frequency. Default is 125 Hz.
`Obj`	HRTFs as SOFA object.
`azi`	Azimuth. Default is -37 deg.
`dur`	Duration in seconds. Default is 1 s.
`fs`	Sampling rate in Hz. Default is 48 kHz.

sig

signal wave form

Complex tone (vowel /a/) with 38 harmonics from Hartmann and Wittenberg (1996) with interaural cue alterations up to a certain harmonic nprime.

The additional optional parameter condition flag may be one of:

`'ILD'`	ILDs up to nprime set to zero. This is the default.
`'ISLD'`	ISLDs (interaural spectral level differeces) maintained while flattening right-ear HRTF up to nprime.
