Pick your poison...2-channel or multi?

"How do you get surround sound from 2 channels. By synthesis?"

Actually Metralla every stereo disc has surround information on it, all you need to do is study a little about the pick up patterns of microphones and mic arrays.

Also realise that all reverb, and delay algorithms are modeled for 360 degrees, not 180, which is all two channel has to offer.

This to me IS the big issue with digital and why it has a noticeable brightness to it when played in 2 channels, there is information compressed onto the soundstage, and since it is room reverberation, or 360 degree delay processing, or just out of phase noise, this information when not moved to its rightful place in the soundfield (rear channels) will negatively impact the spectral balance of playback. A good example is any live albome with an active crowd, most of these recordings are edgy because the crowd is not mic'd and the off axis response of the microphone and the quantity of them, plus room tone and on and on, gets placed between you and the subject, click on surround and the subject (singer etc) smoothes out immensely, your emmerssed in the crowd and all that "noise" is no longer smashed into the front stage, messing up the performer.

Any futher questions, Metralla?

I guess not. Thanks.

Regards,

Metralla...Glad I could help. If you do have a MC question, or even something that you've been wondering about MC, feel free to ask away. However, this forum was intended to help demistify MC, and enlighten 2CHer in the area of MC.

Thanks for the breakdown, D_Edwards.

I've noticed that no one has responded to the previously mentioned question I posed a few postings ago. I must say, its not my intention to be a pest about this, but I'm more than curious as to what legitimite answer anyone can come up with. Sooo.....back by popular demand...I'm posting the same question for the third time. Thanks for you patients!!

Are you aware that the very essense of MC is durived from the same principles of 2CH? Here's the easiest and most practical way I can explain it. Its like getting the same stereo magic between each of the 5 speakers. You know how when a 2Ch setup is locked in, the sound stage is detailed, deep and wide? Now imagine, if you will, this same phenomenon taking place, when done correctly, 5 times over. The results are truely amazing, not a gimmick.

Not only that but the purpose of the five is to really perform like one! Lost you didn't I. You see, when the 5 have been setup and calibrated properly, it creates a 360 degree soundfield. This is just as if your hearing the instrument or voice in front of you (in its orginial intended placement) and the reverb, echo attack and decay, ect...all around you. As if the performance was taking place in the room with you.
