BARUMERLI2023_FEATUREEXTRACTION - extract binaural and monaural cues from SOFA object
Usage:
[template, target] = barumerli2023_featureextraction(sofa_obj)
Input parameters:
| sofa_obj | Struct in SOFA format with DTFs |
Output parameters:
| template | internal templates with specific feature points |
| target | (optional) preprocessed target struct |
Description:
barumerli2023_featureextraction(...) computes temporally integrated spectral magnitude profiles, itd and ild.
Additional input parameters:
| 'fs' | Sampling rate. Default: 48kHz. |
| 'flow' | Low frequency for auditory bands. Default: 700Hz |
| 'fhigh' | High frequency for auditory bands. Default: 18kHz |
| 'space' | Auditory bands spacing. Default: 1 ERB |
| 'targ_az' | column vector to select the binaural stimulus in the templates with the specified azimuth in degree shall be used as target. Use in combination with targ_el. Default: []. |
| 'targ_el' | column vector to select the binaural stimulus in the templates with the specified elevation in degree shall be used as target. Use in combination with targ_az. Default: []. |
| 'source_ir' | Specify a custom sound source to be convolved with HRTFs. The default consider broadband noise. Default: [] |
| 'source_fs' | Sampling rate of the source. Default: 0 Hz |
Further, cache flags (see amt_cache) and plot flags can be specified:
| 'template' | Compute only templates. |
| 'target' | Compute only targets. |
| 'pge' | Use spectral gradients as monaural cues. |
| 'dtf' | Use spectral amplitudes as monaural cues. |
| 'monaural_none' | Do not use monaural cues. |
| 'reijniers' | Compute feature space as in Reijniers et al. 2014 |
| 'source' | Use sound source provided with the parameter source_ir to compute targets. |
