Hello 

I am interested in utilizing a technology called Dolby Headphone which
duplicates dolby surround sound 5.1 channel home theater system.

My question is I have several digital audio files (mp3, etc..) of
nature sounds and animal sounds.  I want to edit those sounds so that
they do not play in stereo sound as they normally do but in dolby
surround sound.  I want to play the sounds so that I can make a sound
appear as if it is orginating from in front of a person or in back of
a person or to the right or left quadrants.  This I know is normally
can be done with a 5.1 dolby digital DVD movie.

I am looking for a software package that will essentially let me
disignate where the sound will appear to come from when a user is
listening to the sound using a 5.1 Dolby digital sound system.

I am assuming that once I can convert a sound to play on a dolby
digital 5.1 surround sound system and appear to orginate from
different quadrants that using the Dolby Headphone technology will not
be a problem.  I found this software app ( www.cineplayer.com ) and it
plays audio and movies back using dolby headphone technology.

Can you help me identify an inexpensive software that will allow me to do this?
