Re: Up-mixing stereo to 5-channels
Reply #4 –
What I'm looking for is something similar to what Dolby Pro Logic II does.
It would make more sense to simply play it back on a system that can decode Dolby Surround (Pro Logic). Any 5.1 channel setup that can play 5.1 DVDs or Blu-Rays should have Dolby Surround decoding and there's no reason* to up-mix it in advance of playback.
But, if it was simply downmixed without being properly encoded it's unlikely that you'll get good results with the Pro logic Movie Mode and you'll probably need to use one of the other soundfield options that are designed for regular stereo.
* The exception would be if you wanted to do your own editing, panning, delay, EQ, etc, with the individual channels. I did that once or twice with concert videos, converting a mono track to surround. For example, I used some stereo-simulation effects, panned the talking between songs to the center, and copied applause from various parts of the recording and mixed it into the rear channels so it was added to the existing regular-stereo applause in the front channels (maybe while fading-down the front channels a bit), etc.
This. Id just run the stereo into a receiver that can do Dolby ProLogic surround processing and it will upmix for you in real time.
