There are basically three
"minimalist" stereo miking techniques discussed here:
Coincident (MS, XY,) Near-coincident (ORTF, NOS) and Spaced (and in this case, spaced omnis, which is the most common). They all have their pros and cons and I will usually pick one depending on the recording project's requirements (i.e., what does the room sound like, what will the record be used for, etc). The picture below will give you an idea as to how the people were arranged for this demo.
As the picture guide says, the students (here, they are "x"s) were set-up in a line in front of the three mic arrays. They counting off from right to left and were recorded on to three stereo pairs of tracks on a DA-88 multitrack. Click on the link below to listen. 1. Coincident, 2. Near-coincident 3. Spaced Omnis. In both the coincident and the near-coincident you should be able to hear the count-off move fairly smoothly from the right to the left. The last example (spaced omnis) should sound quite a bit different. The count-off seems to jump between the speakers instead of there being a smooth transition between the two. Does this mean it's "not as good" as the other two? Well, if you were trying to make an accurate recording of the stereo placement then the Spaced technique probably wouldn't be the best choice. But if you wanted a recording with an exaggerated sense of space (with the side effect of an extended low end response) then the Spaced technique might be the right choice. |
