With ORTF, you have your mic capsules aimed with an exact 110 degree angle difference from each other. Rather than using one mic to capture the left channel and one mic to capture the right channel, the mid-side technique uses one uni-directional mic to capture a signal to be panned to the center and one bi-directional mic to capture a signal panned to the sides. Engineers have been discovering unique techniques for recording in stereo for decades. Store Hours, If you have any questions, please call us at (800) 222-4700. Best of all, since the stereo side channels are completely phase coherent (both derived from the same mono source), they’ll cancel each other out when summed to mono, leaving your final stereo mix completely phase coherent. The distance between the two microphones can vary between 10 centimeters to 10 meters. This bracket makes positioning the mics easy. Some say you shouldn't use it in mono but I disagree. Learn More. Don’t want to worry about phase issues? The Decca Tree itself consists of an arrangement of three omnidirectional microphones — the Neumann M 50 tube condenser is a perennial favorite — suspended around 10′ over the conductor’s head. Now is the perfect time to get the gear you want with simple, promotional financing. The Sabra-som ST2 could very easily be called the Multifunction T-Bar. Don’t use two mics when one is enough. Set the microphones into the openings of the ears, and you’ll have a stereo effect that sounds amazingly convincing over headphones. You simply don’t have enough space for a stereo image to develop until you’re at least 6 feet from the instrument or group of instruments. Although it involves a little bit of work setting up I just like the added control you get with the extra cardioid microphone in the center. The 5 Most Useful Techniques to Know. Here’s how it works. A-B Technique or the Spaced Mic all involving 2 or more Mics X/Y Technique Inside Piano By recording in a mono mix, 1 mic over the treble string side, and 1 mic over the bass string side the sound from both mics can easily control the separated piano tones. Here are 4 specific methods of utilizing a pair of microphones to capture a performance, along with a brief explanation of why you’d choose that setup. Just rotate the mic by 90º, so it’s at right angles to your sound source, and it captures phase-accurate audio from left and right. All you need to set up this totally phase-coherent stereo technique is a cardioid mic (the mid or M mic), a figure-8 mic (the side or S mic), and an M-S decoder of some kind (or some clever summing in your DAW). XY stereo recording uses a coincident pair of directional- or bidirectional, angled microphones. Use the Stereo Protractor mic positioner to get a stereo pair of mics just where you want them. A good idea is to bus the two side channels to a separate stereo bus, so you can control both side volumes with one fader. Most of us are familiar with two or three techniques, but there are well over a dozen great methods to choose from, each with its own particular strengths. The Blumlein Technique Alan Blumlein was a British engineer known for creating and innovating many things in the audio world. the X/Y Technique; Using 2 Small diaphragm Omnidirectional Condenser Mics Placed directly over the strings in the Piano just past the Hammers. Forget miking frustrations! This one is extremely simple to set up — just position two cardioid mics (usually small-diaphragm condensers) at right angles, aligning the front of the capsules, and you’re good to go. Here's a great deal on a complete matched set of sE Electronics sE4400a condenser microphones. This method is ideal for close-mic applications and provides a clear but not terribly wide stereo image with minimal phase issues. Next time you need to record in stereo, we hope these methods help to fuel your creativity. When one mic is heard through the left monitor, and the other mic through the right, it creates a pleasant sense of width that is absent in a mono recording. Sweetwater Sound Notice how the mics in this figure are attached to a special mounting bracket. As great as it sounds on headphones, the only downside of binaural is that it doesn’t translate as well to spaced loudspeakers. Pro Tip: Depending on where you position your Blumlein pair, you can pick up more or less of the room ambience. Some stereo mic techniques specifically enhance the spatial field, while others are better at focusing it. To help facilitate stereo separation and reduce phase problems, a pair of microphones may be isolated with an absorbent baffle.
