One Cab. Think about spaced pair as a mono overhead and a significant other mic somewhere else.
Depending on the space, this may not be possible.
The Audio Solutions Team explores which stereo microphone techniques can be used with A-T microphones, including the spaced pair technique. This stereo mic technique involves spacing a pair of cardioid or omnidirectional microphones apart in such a way that they cover the space but dont create phase issues for each other. For sharp imaging, the microphone pair should be well matched in frequency response and polar pattern. The second mic looks over the shoulder of the floor tom towards the hi-hat. July 18, 2022. 2. It mounts two mics on a single stand, and lets you adjust the angle and spacing between the mic pair. The 3-to-1 rule must be followed to prevent phase issues. Blackbird Studio ace Bryan Clark breaks down the versatile studio technique and provides some advice on Three of the most popular are the spaced pair (A/B), the coincident or near-coincident pair (X-Y configuration), and the md-side (M-S) technique. This technique uses two cardioid or omnidirectional microphones placed a moderate distance from the sound source, pointed straight ahead. Spaced pair miking is exactly what the name implies. What Stereo Microphone Techniques Can Be Used With A-T Mics? Two cardioids spaced a foot or two apart are placed at or around the unhinged side opening of a grand piano. Time Difference Stereo. This describes the 3:1 ratio rule, which we will talk about soon and helps with mono compatibility. The outer limits of the recording angle should be reproduced at 30 (time difference approximately 1.1 ms). The crossing point is marked (): Hence, the spacing (d) should be 40 cm (16 in). XY stereo recording uses a coincident pair of directional- or bidirectional, angled microphones. Spaced pair offers dual perspectives of the sound source and relies heavily on what is called the phantom center. Spaced microphone stereo techniques using an acoustic absorbent baffle. With the spaced pair technique, two identical mics are played several feet apart aiming straight ahead towards the instrument or musical ensemble. One of the most common stereo miking techniques is AB Stereo or spaced pair. I have already had some success with this technique but cannot seem to find the answer to one question. The most obvious stereo mic setup is the spaced pair (sometimes called AB, see Figure 1). We take a practical look at the pros and cons of coincident and spaced stereo miking techniques.
Spaced Pairs. Infinite Tones. This technique reproduces both timing and volume discrepancies, making it, in some sense, a hybrid of the spaced pair and XY techniques. Fist overhead is placed 3-4 feet above the snare. Therefore, the spaced pair miking technique can be used to create an unnatural stereo image. Sometimes this is exactly what you need. 2. X/Y, Coincident One issue that occurs when there are timing difference between signals is phase cancellation. The distance between them will create time-of-arrival (phase) and level (amplitude) differences in the input they receive. One mic goes above the left side of the kit pointing down, the other goes on the right. The capsules are spaced about 17cm, or just over 6.5 inches, apart. Make sure both mics are equally distanced from the snare. In an ORTF pair, its the backside of the microphones that are near touching, rather than the front-side. This pattern also works well with a stereo bar, saving on space and mic stands onstage and in tight spaces. AB/Spaced Pair. This is often used for relatively large sound sources, like an entire drum kit or a grand piano. Perhaps because the microphone position simulates human ear position, the resulting stereo field seems very natural and realistic, and generally collapses to mono without significant problems. It brings out the sound of the room.
Spaced Pair.
2. Perhaps more than any other method tested, the spaced pair approach requires care to avoid phasing problems. 2018-04-08 By WikiAdmin Leave a Comment. By placing two microphones several feet apart, a wide stereo image can be achieved.
Time differences and level differences between the two mics generate the stereo image. This video demonstrates and discusses spaced pair miking. (2 matched Microphones are used unless stated). Two mics (often omni) are set some distance apart, delivering stereo information by differences in loudness and precedence.
With ORTF, you have your mic capsules aimed with an exact 110 degree angle difference from each other. 1. From XY and ORTF to Mid-Side, Decca Trees and Spaced Pairs, see and hear some of the most effective tactics for placing stereo microphones. The coincident crossed pair is the simplest and most basic stereo microphone technique offering precise imagery and full mono compatibility. STEREO MICROPHONE TECHNIQUES by Bruce Bartlett Stereo miking is the preferred way to record classical-music ensembles and soloists, such as a symphony performed in a concert hall or a string quartet piece played in a recital hall. The space paired technique is the easiest of all the stereo microphone techniques and is simply two microphones placed in front of an instrument, with one being placed to the left and the other to the right. Another option, and one of my favorites, is a sort of modified ORTF array. Youll get a smooth, spacious sound. A common mic placement with a lot of flexibility for your sound is placing a pair of spaced room mics equidistant from your drums, one panned hard left and one panned hard right. As an example, lets say the snare drum resonates at 400Hz. It accompanies Ch.
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 increases the stereo width and decreases the strength of the center. 2. A-B Stereo For medium-distance stereo miking for choirs, orchestras, and even drum kits, A-B stereo may be your best bet. Baffled stereo is a generic term for a lot of different stereo techniques using an acoustic baffle to enhance the channel separation of the stereo signals. The spaced pair is the other of the most common overhead drum miking techniques, although there are an infinite variety of ways to do it. Two cardioid microphones are placed apart from each other to produce two different recordings of the same instrument. With this technique, you can play around with different distances and heights of your mics until you are happy with the outcome. When you record using the X-Y technique, keep these points in mind: The stereo image (the placement of the instruments in the sonic environment) isnt as wide or realistic as it is in real life. Spaced Pair. I suggest trying two places on the instrument that produce different tonalities. Figure 1 - Stereo spaced guitar front. The ITDs and IIDs 2. It is possible to record any group of acoustic instruments, or whatever size, using just two microphones in the coincident crossed pair configuration. The A/B stereo recording technique is also known as Spaced Pair. The X-Y stereo mic approach uses two matched microphones placed close together. All refer to the same basic technique. A variation on the spaced pair is the Decca Tree, which adds a center mic to a pair spaced approximately 80 apart on a large T-shaped bar. A spaced pair of room mics. AB Mic Technique (Spaced pair) 2 omnidirectional mics of the same make and model, 3-10 feet apart. Then use ears, and pray to the spirit of Led Zep. The mic closer to the keyboard can be The AB or Spaced Pair approach is among the simplest stereo techniques to understand, but it presents the most problems in practice. Back in the 1960s, Spiderman and Superman comic books from the USA had a middle section of pink-paper advertisements for pretty unbelievable technical gadgets. spaced pair This is probably the most common method for miking overheads. 4 Common Stereo Microphone Techniques 1. The distance between the two microphones can vary between 10 centimeters to 10 meters. This technique uses two mics: a figure-8 mic for the side channels and a cardioid mic for the middle channel. The spaced pair technique is when two microphones are positioned with at least 16 inches of space between each other and are pointing an equal distance towards the same source.
Some also add a third center microphone to strengthen the center image. Infinite Tones. Technique Position the two microphones close to the guitar at approximately 30-50cm away. Also, we will listen to coincident pair and spaced pair stereo techniques. Also called spaced pair this is a technique where two stereo microphones are placed anywhere from 3 to 10 feet a part to create a time difference that the brain perceives as a stereo imaging effect. Bryan Clark. How to Record Guitar with Spaced Pairs Technique | Recording Dojo. A-B Stereo is known by a couple of other names. Glyn Johns is a method that was developed as a compromise between Spaced pair and more focused methods. In this video, Mr. B discusses phase cancellation and mono compatibility. a stereo microphone technique that utilizes two microphones placed with a relatively large spacing between microphone elements. The angle is slightly wider than that of XY, at 110 degrees. Compared to the other stereo techniques we describe below, a spaced pair typically provides the widest and most dramatic stereo image with less room acoustics but more chances for error, since the mics are farther apart. When 3. Broadly speaking stereo micing techniques can be put into 3 categories Non-coincident, coincident and near coincident. The mics must also be spaced exactly 17cm apart. The ORTF mic technique, sometimes referred to as Side Other Side was developed in the 60s for Radio France (ORTF stands for Office de Radiodiffusion Tlvision Franaise). To avoid phasing issues, both microphones should adhere to the 3 to 1 rule and be positioned apart from each other at exactly the same height. Two Mics. It involves two microphones positioned anywhere from 3 to 10 feet apart, meant to capture the same sound source. Spaced omnis are often used for recording orchestras, either alone or mixed with a coincident pair to add width. The details about one of the most basic and useful stereo mic techniques By Phil O'Keefe One of the most commonly used stereo mic techniques is the A-B Stereo pair. .
While it might seem to be the ideal configuration, because it preserves both timing and volume information, ORTF can be difficult to master, and can sometimes produce unpleasant results when played back in mono. X/Y, Coincident. youtu.be. I have read a lot of posts regarding the technique put forth by Tony Faulkner, among others, where you use a near-coincident pair of mic's flanked by spaced omni's on the same stand. The spaced pair technique can be used with omni, but mainly uni-directional microphones. Figure 2 - Coincident guitar front. The X-Y technique involves a pair of cardioid microphones of the same make and manufacture placed with their heads facing as close together as possible at an angle of around 90-110 degrees. One issue that occurs when there are timing difference between signals is phase cancellation.
Spaced pair ORTF.
