What is ORTF recording?
ORTF is a common stereo mic technique. Stereo recording uses two microphones to capture a single sound source; each mic then gets panned to either side of the stereo field. Over the years, engineers have developed tried and true methods of stereo recording that best mimic how our ears perceive sound.
What is ORTF audio?
An abbreviation for Office de Radiodiffusion Télévision Française (French Radio and Television Office). Also a name for a specific microphone setup for near-coincident stereo recording with two cardioid microphones.
What is the angle of an ORTF pair of microphones?
ORTF combines both the volume difference provided as sound arrives on- and off-axis at two cardioid microphones spread to a 110° angle, as well as the timing difference as sound arrives at the two microphones spaced 17 cm apart.
What is XY stereo recording?
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. In practice, “coincident” means that the microphone capsules must be placed close and normally slightly above each other (fig.
Is ORTF mono compatible?
ORTF can create a beautifully wide stereo image and still deliver some mono information. One disadvantage is that a sound source in the center of the stereo image will be off-axis from both microphones, limiting frequency response.
What is good microphone technique?
You should hold the microphone at a distance of 10-20 centimetres away from your mouth. You should hold it further away at a distance of up to 20cm when you sing higher or more powerful notes. If you move around and turn away from the stage always maintain the same distance.
What is AB recording?
April 28, 2020. The A/B stereo recording technique is also known as “Spaced Pair”. It involves two microphones positioned anywhere from 3 to 10 feet apart, meant to capture the same sound source. The distance between them will create time-of-arrival (phase) and level (amplitude) differences in the input they receive.
What are XY microphones?
What is XY in audio?
A stereo miking technique that employs two cardioid microphones angled 90 degrees from each other, but positioned at the same point (or as near as their physical size will allow).
How do you record blumlein?
The Blumlein Pair technique utilizes two microphones with a bidirectional (figure-of-eight) pickup pattern and positions them on top of – and 90 degrees off axis from – one another. Positioning the microphone elements as close together as possible will help phase coherence.
How do you use the XY mic?
1. XY Stereo. If you’re like most engineers, then the XY technique is probably the first stereo miking technique you learned. 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.
How do I set up my blumlein mic?
What is mid side recording?
Mid-Side is a coincident technique, meaning that both mics are placed as closely as possible to each other and the stereo image is created by differences in loudness rather than time delays, on which other stereo miking methods rely. Mid-Side uses a mid mic, which usually has a cardioid pattern, but can also be omni.
How do you record acoustic guitar XY?
A simple approach to stereo miking is the coincident X-Y method. With X-Y, two cardioid microphones of the same model are set up with capsules placed as close as possible and facing each other at a 90-degree angle.
