imaging on recording
What type of localization of images is possible on a recording? Up, down,
back, forward, left and right? Is it possible to say for sure? |

Anything you can sucessfully sample at a high enough sample rate - ie. enough mics and speakers... On a *stereo* recording there is only Left & Right. Everything else is an illusion recreated by your mind to comply with your previously learned auditory view of the world. The recording provides cues that permit you to "decode" the sound into something other than mere left and right. But having said that, there is no possibility of up or down with a stereo speaker placement. Left, right, center, front and back are the possible decoding options for your ear/mind combo. You can get far left, far right with out of phase signals too. _-_-bear |

What would cause an image to shift up or down when appying EQ/ I heard this happen many years ago when demosnstrating one to a potential customer. I was standing to the left of both speakers at the time and the customers in front of them, we all heard thesame effect. |

or down when appying EQ/ I heard this happen many years ago when demosnstrating one to a potential customer. I was standing to the left of both speakers at the time and the customers in front of them, we all heard the same effect. It would seem that the frequencies being boosted by EQ would be reflected off of something higher in the room. I notice in my system that high strings seem to come from higher up. An example is in the beginning of the overture to Die Meistersinger where the violins go way up high. This effect is even noticed on a mono recording. ---MIKE--- In the White Mountains of New Hampshire (44=B0 15' N - Elevation 1580') |

All localization that can be done with your head steady, can be reproduced by two channels using binaural recording played back in headphones. Think about it; you only have two ear canals, and if your head is not moved, the information in these two "channels" is enough to get a lot a localization cues. If we grab this information in the ear canals and time shift it, using a two channel recording, we haven't changed anything. Loudspeaker reproduction is another story, of course, but given enough channels should make it poosible to reproduce any imaging you want. Put perhaps you were thinking of stereo, only? Per. |
