What is XY mic technique?
X-Y (coincident) stereo miking consists of using two microphones that are placed right next to each other so that the diaphragms are as close together as possible without touching one another. This bracket makes positioning the mics easy. The X-Y stereo mic approach uses two matched microphones placed close together.
What is NOS mic technique?
The NOS stereo technique is a method of capturing stereo sound. The Nederlandse Omroep Stichting (NOS, English: Dutch Broadcast Foundation) found a stereo main microphone system by a number of practical attempts in the 1960s. This technique leads to a realistic stereo effect and has a reasonable mono-compatibility.
Which stereo mic technique uses coincident placement?
Setups for stereo: XY. XY stereo recording uses a coincident pair of directional- or bidirectional, angled microphones. Hence, the directional information is obtained solely from the level difference between signals.
What is XY mic placement?
The X-Y technique consists of two identical cardioid microphones, placed on top of each other while facing away from each other at a 90 degree angle.
What is a coincident pair?
A coincident pair is a pair of microphones positioned with their capsules as close together as possible. The capsules are pointed in such a way that a stereo image is possible when panning each microphone.
Is xy a coincident?
What is an XY mic? An XY mic is a stereo microphone with two capsules set up in a coincident XY stereo pattern. These two capsules are placed very closely together and point outward with an angle of 90°-135° between them—the mics output two signals that are later panned in the mix to achieve a stereo image.
What is near-coincident pair?
A near-coincident pair is any stereo miking technique that uses a pair of microphones spaced roughly 6-12 inches apart and angled symmetrically on either side of the centre. Near-coincident pairs are often preferred for their stereo image since their mic positions simulate human ears.
What is a coincident microphone pair?
Is coincident pair compatible with mono?
It is sometimes lumped in with the coincident pairs, though, so I’ll describe it here. The mid-side technique is designed to yield a stereo image that is perfectly collapsable into mono. This means that the mid-side arrangement allows for perfect mono compatibility, unlike nearly every other stereo miking technique.
Is ORTF a coincident pair?
ORTF mic technique uses a “near-coincident” pair of cardioid microphones. ORTF stands for Office de Radiodiffusion Télévision Française. Radio France invented it as an alternative to X/Y. As a near-coincident pair, the mic capsules are spaced 17 cm (~7 inches) apart and pointed outwards at a 110° angle.
How do you set up a Decca Tree?
A Decca Tree configuration is characterized by having three omnidirectional microphones in a “T” shaped setup. Two of the microphones are positioned about two meters apart. The third microphone is positioned between the first two, but about 1.5 meters forward (closer to the source) of them.
What is the coincident pairs method?
In this method (also called crossed pairs and sometimes called the X-Y method, although X-Y is often used to refer to a specific version of coincident pairs) a pair of microphones are set up in such a way that their capsules are almost touching or one is directly above the other and angled apart. In other words the capsules are coincident.
How do you find coincident lines?
The lines representing these equations are said to be coincident if; a 1 /a 2 = b 1 /b 2 = c 1 /c 2 Here, the given pair of equations is called consistent and they can have infinitely many solutions.
What is an example of a coincident equation?
Example: Check whether the lines representing the pair of equations 9x – 2y + 16 = 0 and 18x – 4y + 32 = 0 are coincident. Therefore, the lines representing the given equations are coincident.
How to choose between x-y and near-coincident techniques?
In that case, the X-Y method should be used. If a better stereo image is desired and some compromise can be made on mono compatibility, then one of the near-coincident techniques should be the choice. Whatever configuration is picked, some experimentation is in order.
