In comparison to the Ambiophonic Audio Player (APP) which takes WAV audio files to apply the Recursive Ambiophonic Crosstalk Elimination (RACE), the Ambiophonic Transcoder reads audio data from any input-mixer/device (e.g. "What-U-Hear"/Stereo Mix, SPDIF-IN, LINE-IN) and plays them back through the output mixer (e.g. LINE-OUT, SPDIF-OUT).
Now you're able to enjoy Ambiophonics for any source by connecting for example your CD/SACD/LP or iPod to your computers line-in and your HiFi Equipment or PC-Speakers to the sound cards line-out jack.
If you have more than one sound device or "virtual sound devices"/"virtual cables" then you can use your favorite music player (e.g. iTunes, Foobar2000, ...) and configure the Ambiophonic Transcoder in a way that it takes the input from the stereo mix (What-U-Hear) to play the audio to the selected output mixer/device.
