Anyone know of a software plugin that can convert standard stereo or dolby stereo to surrounf 5.1? Like the TC electronics Unwrap or Z-systems K6 processor.
Been fiddeling around with manual remixing the stuff but I got a feeling that it shouldnt be to hard to make something like this, most of these processor basicaly devide the channels on their stereo spread and frequency.
If there's not, is there a 'standard' way of filtering for frequency, stereospread?
