Can SurCode or discWelder products turn my standard stereo audio files into high-resolution surround?
20. No, nothing can create true surround from stereo or mono files (say a helicopter flying in a circle around the speakers). Your surround receiver should already have settings to get the signal to all the speakers, or you can use your receivers Pro Logic II decoder to simulate surround sound. Up-sampling audio does not improve the audio quality of the sound file and takes up more space, so we see no need to offer up sampling as an integrated feature.
