Interesting topic.
I compiled the tool, created a dts file from my 44/16 wav:
./dcaenc 441-16.wav 441-16.dts 1411200
The resultant 441-16.dts plays fine in mplayer.
Encapsulating the dts file into wav:
sox -t raw -s -c 2 -b 16 -r 44100 441-16.dts 441-16-dts.wav
Format check:
soxi 441-16-dts.wav
Input File : '441-16-dts.wav'
Channels : 2
Sample Rate : 44100
Precision : 16-bit
Duration : 00:01:00.00 = 2646016 samples = 4500.03 CDDA sectors
File Size : 10.6M
Bit Rate : 1.41M
Sample Encoding: 16-bit Signed Integer PCM
Plays fine in mplayer too:
mplayer 441-16-dts.wav
Playing 441-16-dts.wav.
Audio only file format detected.
