shorten(1) is very outdated, so there would be no benefit adopting it over nist sphere tools. Current programs that support .shn files and the shorten compression are ffmpeg/avconv, but I doubt they can directly uncompress a shorten'd .sph. It all gets complicated quickly. But using sox on uncompressed sets like TEDlium is probably more portable. If anyone has a sample shorten-compressed .sph file, send it my way please. -kkm > -----Original Message----- > From: Jan Trmal [mailto:jt...@gm...] > Sent: 2015-05-13 0315 > To: Kirill Katsnelson > Cc: Anthony Rousseau; Dan Povey; kal...@li... > Subject: RE: [Kaldi-developers] sph audio, sox vs sph2pipe > > I remember I tried several times and I had the problems with "shorten". > > Sox refuses to work with those sph files. > > What I did IIRC, I took shorten.exe (I don't remember where I got it, > but something can be found here: > http://www.rarewares.org/lossless.php), > which does not support sph format -- but has some switch that allows to > ignore first 1024 bytes of the recording (or something like that).
