| Crystal Method's "Legion of Boom" was remixed into 5.1 and 6.1 for the DVD-Audio release, and the result truly is astounding. I've been a big supporter of multichannel audio for some time now, and I'm glad to see that it's starting to catch on a bit more with the recent support of the Dualdisc format. Hopefully some more dance/electronica artists will see this as a viable opportunity to enhance their music. |

So, for home listening, multichannel audio had been producted on dvd-audio, though the demand has not been that great to make it that popular.
And for club listening, there is inherit limitibility in vinyls for multi-channel, unless some new technology comes up. |

Not true. All your current DVD titles are all in 2-channel. They are converted/decoded to 5.1/7.1/8.1 or the latest 9.1(with ceiling surround speakers as well) by an 'A/V reciever'.
It's kind of hard to do for music because it dosen't really have point sources of sound like a movie. |

Not true at all! While many DVDs do have a stereo track, most major motion pictures have a Dolby 5.1 track mixed specifically for home theater systems - some have a DTS track as well. That's not the argument I'm going after, however.
The process I think you're referring to is called Dolby ProLogic. It takes a stereo signal and upmixes it to 5.1 by comparing the information in both channels. If the audio in both channels is exactly the same (this usually includes main vocals or drums in a song, or dialogue on a television show) it's put to the center channel. If the information is out of phase (usually echos or ambient noise and chorus vocals in music, and off-screen effects and enviornment noise on a show or movie), then it's put to the rear speakers. They usually get the LFE/sub audio by doing a low-pass (80hzish) to the audio signal. The left and right channels are more or less kept the same.
This process usually yields pretty good results for music, but the problem is it couldn't really be done well in clubs for one simple reason: people don't stay in the exact same place facing the DJ the entire night. Listening to music in surround sound is simply a different experience than dancing in a club. Multichannel audio is for hearing and experiencing...music in a club is more or less for dancing. I doubt many people would even notice if you downmixed your final output to mono. |

How do you cut surround sound vinyl then? |

Ive been to an event that had eight channel diffusion. there are many venues that use surround sound. the first thing that comes to mind is...wouldnt that be awkward when trying to mix? for instance when your trying to monitor, all these sounds comming out of everywhich way. too me...that sounds like it would be a bitch. ive never played live, let alone on a surround system, so i really couldnt know that. |
in the theory i guess its not a problem....
you can have a normal stereo output for the monitors only, all channels mixed to 2 monitors, and surround for the rest of the club... |

Yup, I was referring to Prologic but wanted to put it across in laymen's terms. :d
Actually speaking, Prologic just produces a 'virtual' surround illusion.
Personally, I don't think club music would sound good in surround sound. Most multi-channel/home theater experiences require you to be stationary for the full experience. Not possible in a club.
However, they could do it for trance videos :D |

I doubt that it is practically possible and feasible. |

Your theories are right except that its Dolby Digital, and not Dolby ProLogic that seperates the sounds into descrete channels.
ProLogic merely takes the sounds and distibutes them among 5 channels, where Dolby Digital is a pre-mixed 5.1 audio track. True seperation can only be attained through Dolby Digital.
An internal DAC (Digital Audio Converter) is what allows the receiver to play the Dolby Digital track.
Most audiophiles believe that 2 channel stereo is still the best way to listen to music. I have a DVD-Audio player in my car and there really isnt much difference, except for once in a while, between it and 2 channel stereo. |

There were at one point quadraphonic record players. They had four needles on them and quadraphonic records would have 4 grooves in them instead of one. Each needle would read a different track. The idea really never caught on but it does show you that some type of surround sound is possible with vinyl.
If you get a high quality A/V receiver nowadays you can play your regular 2 channel cds on it and the receiver will try to put the music in surround sound (I think they call it Pro Logic II). You don't get a perfect surround effect but most of the time it sounds pretty good. |
