    What I am talking about is converting the actual track into a 5.1 track. I have been working on a project using adobe premiere pro cs3. I had to record someones voice threw the microphone on my laptop for some voice over. The audio thread I recorded is in sterio, but I need to get it to 5.1. The reason for this is because I can not make the track any louder with out peaking it out. I finished my project burned a dvd when it played in the dvd player it was too quiet. I need the volume to come out of all of the speakers for full resolution. Does anyone know how I can turn this track into a 5.1? I am very new to this and so please talk as basic for me as possible.

    Even if you convert to 5:1, will it make it any louder?
    Better bet is to use an audio editing program to compress and
    then normalise.
    Sound forge has a normalize function that does it based on average
    values, not peak, and will do dynamic compression if necessary.

    I'm not too sure about this but i thought you had to record it in 5.1 surround sound, many software packages have a plug in for recording in 5.1 surround sound. If your looking to make the sound louder overall, then I would normalize with cool-edit or logic, cubase pluging etc.. After normalization you could then amplify it a little. What kind of mic did you use to record? (Adobe uses Cool-Edit.) I would try to find a cool VST plugin for mixing of the tracks. There are even mics that can record in 5.1 sound. And the pros record each track for 5.1 encoding. Meaning that each track you recorded is encoded to 5.1. You will need the original mix. But if you just want to make sure that the 5.1 DSP converts the stereo to 5.1 sound which it can do, then you might want to try different recording software. Try playing it on a ipod and then play it through 5.1 reciever. You might notice the sound is playing on all speakers. I'm not too sure why this is but it is converted to a AIFF.Also most dsp on PCs will process it for 5.1 sound. Try winamp. Meaning that it will play it on speakers, though you will have no control on what is actually played through the front center and rear speakers. (you might just hear echoes through the rear speakers. T ) If your trying to control what is played on the speakers, then you will need a plug-in or software. You might have to record again. THis might be why your not hearing it on all speakers. I'm not too sure but you should not have to actually record in 5.1 to hear the music with a 5.1 dsp. Usually the DSP will handle it for you, but I have noticed that sometimes the DSP will not properly process the mix only playing it through the center and/or front speakers them selves. I use to record mixes for DJ's so I have a little experience with recording. Remember that what you hear on one speaker will sound different on others. And also you might have more luck if you used mastering software. Here is a link to record in real 5.1. Good luck and let me know how everything is going. Looking to learn about this as well. Just a thought, it might be due to your mic.
