elastix 2.3 64 bit sox sln support missed?

[witekprytek]

Hi I have installed elastix-2.3.0-7. 64 bit version
I have noticed that the sox (sox-12.18.1-1.el5_5.1 sox-devel-12.18.1-1.el5_5.1) does not support sln format.

" sox -h
sox: Version 12.18.1

Usage: [ gopts ] [ fopts ] ifile [ fopts ] ofile [ effect [ effopts ] ]

.....

Supported file formats: aiff al alsa au auto avr cdr cvs dat vms gsm hcom la lu maud nul ossdsp prc raw sb sf sl smp sndt sph 8svx sw txw ub ul uw voc vorbis vox wav wve

"

Is it correct?


What woice format is recomended to use insted of sln?
