Hi. Just a short info.
For those who would like to play stereophonic sound files
(or movies with stereo sounds) and reproduce it in 5.1 speakers
environment, please use our DirectShow decoder (Aud-X codec).

Also, the sound (during the real-time conversion to 5.1) can be directed to SPDiF output and sent in AC3 format to the external home theatre system.

So, in fact the DSP processing graph inside the decoder is
Input -> [Resampling to 48 kHz] -> [PseudoSurround] ->
( [5.1 SoundCard PCM] or [AC3 for SPDIF] )

It is very easy to achive. Just by chosing the right decoder option.
If the input is mono or stereo, it will be converted to 5.1 (surround).



More information about the algorithm is available in our whitepaper
(www.aud-x.com in Laboratory section. The codec is available in the Download section)
