Midside technology uses a microphone tuned to a cardioid polarity pattern, but omnidirectional patterns are also available. This microphone is arranged to capture the sound source directly. Therefore, the term “center” is a microphone that literally picks up sound from an audio source in front (not on the sides). Instead of creating a stereo image through time delay as in XY recording, Mid-Side captures the stereo effect through the volume difference between the microphones used. , given that the microphones are very close together? The midside is called “simultaneous” recording technology. This basically means that both microphones are located as close as possible. When in doubt, use your ears, reevaluate your mic placement, and make adjustments to get the results you want. Pro Tip: Any time you have microphones covering the same sound source from different distances, you’re likely to run into some phase problems, as the offset in distance causes the sound to reach the microphones at different times. The stereo separation you’ll experience with a baffled A-B stereo pair is even more pronounced if you use omnidirectional mics. Commonly known as a Jecklin disk or the modified Schneider disk, when properly applied, a baffled pair may be much closer together than a regular A-B stereo pair. To help facilitate stereo separation and reduce phase problems, a pair of microphones may be isolated with an absorbent baffle. Both signals mixed to mono produce the most extreme phasing effect.ĭepending on the space, this may not be possible. When not panned like this, the same time or phase differences will produce phasing in the output, to varying degrees. For this, we need to pan the mic tracks hard left and right, respectively. This is usually enough to match the location of a sound source to that of one of our stereo system’s speakers. Level and time-of-arrival differences can be used to recreate location cues our ears receive and brain use to locate sound sources across the horizontal spectrum. For example, at a distance of 60 cm from each other, microphones can capture a source with a time difference of 1.5 to 1.7 milliseconds. These will be more evident as we increase proximity to the sound source. The distance between them will create time-of-arrival (phase) and level (amplitude) differences in the input they receive. It involves two microphones positioned anywhere from 3 to 10 feet apart, meant to capture the same sound source. The A/B stereo recording technique is also known as “Spaced Pair”. This increases the stereo width and decreases the strength of the center. Pro Tip: You can explore many variations on the standard XY stereo mic technique by making the angle of the mics greater than 90 degrees. This can cause the recorded sound to become dry or muffled, depending on the sound of the room. Matched pairs provide excellent position accuracy. The sound arrives from the side at the same time, making it easy to locate each player on the stage. In this way, the sound reaches each microphone at the same time. Stack them and place them as close together as possible in a horizontal array. The microphone head should be at the bottom of the V. In this arrangement, mount the microphone so that the microphone is placed horizontally V so that the bottom of the V faces the stage. There are several different X-Y pairings, the first of which is simultaneous pairing. Both the position of the microphone head and the angle between the microphones are important here. In an X-Y pair, two identical microphones can be mounted together in one place.
