5.1 audio cd

[Diablo0825]

I have abunch of mp3s on my computer and I would like to convert them so they sound great on my 6.1 system. I'll settle for 5.1.

Not sure how to do it if it can be done at all but i do know that if you plan to burn a regular cd (but with 5.1 sound) you will need a SA-CD compatitable player in order to play the 5.1 sound .. other wise if you use a regular player it will just play in stereo like a normal cd

simply converting up to 5.1 from stereo...I don't think that will make it sound any better. (remmber: it will only sound as good as it's source) What are you trying to achieve? Are you just trying to get the sound to come out all 5 speakers at once? This can usually be done from the reciever (as a special 'mode') Or are you actually trying to introduce seperation? Either way, you want to read this page for what you are doing:

It depends what you want to do, although as Mike 909 pointed out since there is no information for a 5.1 or 6.1 signal, there will in general be no sound improvement and considerable opportunity to worsen the sound. The other issue is how are you going to play it? Are you considering some sort of audio DVD? or just something to play from the computer?

With that said, there are a lot of threads over at Doom9 on how to convert stero to pseudo 5.1, etc. I played around with the soundtrack from my Laser Disk original Starwars dics. Separating and boosting a LFE channel, putting in some surround by creating rear channel tracks and adding a bit of delay and presence. It is certainly an interesting exercise, but after watching it once I simply went back to the original stereo. I probably was a bit to heavy with the effects, but it didn't sound right after a while. I have done a few just LFE channels to take better advantage of the subwoofer. And I used to add unchanged rear channels, but that's easier to do by just by throwing a couple of switches on my receiver (although that's not true with all receivers).

Surcode has software dedicated to doing this. It creates wav files containing multi-channel DTS (and probably AC3) audio with a sample rate of 44.1 (as opposed to DVD's rate of 48). DTS officially support this format, not sure that dolby do, however it can be done.

These disks can only be played back on a device attached via a digital connection to a decoding amp, otherwise they produce pink noise that may damage speakers.

That said, you are really wasting your time if you are going to start with mp3 source files. MP3 compression kills stereo seperation, causing muddy cross over. Even with high quality stereo source, creating real 5.1 is a fool's errand. Starting with something as poor as MP3 is more than a waste of time.

Most decent sourround systems have options for playing back stereo content such as NEO6. While I have encoded a stereo concert DVD with 4.1 sound (stereo in LF [slightly louder],LR,RF[slightly louder],RR and SubWoofer) and it did sound cool all other attempt at "upscaling" to 5.1.
