Hi, i'm a newbie and a bit confused, i've down loaded a avi file in three 700MB segments which are in 6 channel or 5:1 surround sound off of a file sharing program or network.
The program has a detail section showing if the files are corrupt etc, and there's a section showing audio compression, but each file has varying audio compession, say one file has 1.6MB of compression, the other will have 3.0MB etc.
I usually join the files together with VirtaulDub into one file and encode and burn to dvd which keeps the 6 channel sound.
My confusion is why is the audio compression different for each avi file, i assume that it's caused because a downloaded them through a file sharing network and the audio may have been corrupted.
So i used VirtaulDub to uncompress the audio thinking this would correct the audio but instead it turns the audio from 6 channel or 5:1 surround sound into stereo with a very high birate.
The files are obviously larger and play as normal, but why do i lose the 6 channel audio when uncompressing it, is it normal for each segment to have varying audio compression or is this corruption of the audio when downloading.
Well i guess that's about it and i'm truely sorry for my ignorrance and this big boring post but any help would be much appreciated, thanx.
P.S. is compressed audio a fault or corruption and if so can i uncompress the audio with VirtualDub and still keep the 6 channel audio and will this have any effect on quailty.
