sarc - slab3d archive help.
The slabtools slab3d archive (sarc) format is used to archive, view, analyze,
and manipulate HRTF data.
A slab3d archive file is a MATLAB MAT-format binary file containing one slab3d
archive struct variable 'h'.
A slab3d archive struct contains the following fields:
name - subject name
date - sarc creation date
source - source of data (e.g., 'snapshot', 'headzap', 'slabslh', 'cipic',
'custom' )
comment - comment string
ir - HRIR data, all left ear data followed by all right ear data
itd - ITD data, #samples left lags right
dgrid - data grid (az,el order, elevations grouped by azimuth)
finc - dgrid fixed increment flag
azinc - fixed-inc az increment
elinc - fixed-inc el increment
fs - sample rate
mp - HRIR minimum-phase flag
tgrid - measurement grid read by head-tracker
eqfs - EQ sampling rate
eqm - mixed EQ (e.g., Snapshot eq)
eqf - free-field EQ
fgrid - free-field EQ grid (elevations grouped by azimuth)
eqd - diffuse-field EQ (all L then all R)
eqb - bass-boost EQ
eqh - headphone EQ (invL,invR,m1L,m1R,m2L,m2R,m3L,m3R)
hcom - headphone comment describing model, type, and coupling
Depending on the archive, some fields may be empty.
The following functions are used to manage slab3d archives:
sl sarc list
sload sarc load
ssave sarc save
smake sarc creation
sinfo sarc info
slab2sarc create slab3d archive from slab3d HRTF database (.slh)
snap2sarc create slab3d archive from Snapshot archive
zap2sarc create slab3d archive from HeadZap archive
cipic2sarc create slab3d archive from CIPIC database
cam2sarc create slab3d archive from IRCAM database
The following functions use slab3d archives:
hlab HRTF Lab application
vir impulse response viewing utility
vitd ITD viewing utility
vall utility for viewing all el's for az or all az's for el
hcom HRTF database comparison and quality measurement utility
hen displays table and graph of HRIR energies
henfilt similar to hen() but performs white noise filter
