The ORTF stereo technique, also known as side-other-side, is a microphone technique used to record stereo sound. It was devised around 1960 at the now-defunct Office de Radiodiffusion Télévision Française (ORTF). This technique combines both the volume difference and the timing difference as sound arrives on- and off-axis at two cardioid ...
The inset shows the electronic simulation. Notably, such electronic systems require more than one speaker. Time difference in a stereophonic recording of a car going past. Stereophonic sound, or more commonly stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective.
Headsets are made with either a single-earpiece (mono) or a double-earpiece (mono to both ears or stereo). The microphone arm of headsets is either an external microphone type where the microphone is held in front of the user's mouth, or a voicetube type where the microphone is housed in the earpiece and speech reaches it by means of a hollow tube.
A sound reinforcement system is the combination of microphones, signal processors, amplifiers, and loudspeakers in enclosures all controlled by a mixing console that makes live or pre-recorded sounds louder and may also distribute those sounds to a larger or more distant audience. [1] [2] In many situations, a sound reinforcement system is also ...
The Nederlandse Omroep Stitchting ( NOS) stereo technique is a method of capturing stereo sound . The Nederlandse Omroep Stichting (English: Dutch Broadcast Foundation) found a stereo main microphone system by a number of practical attempts in the 1960s. This system resulted in a quite even distribution of the phantom sources (hearing event ...
In the middle of the cavity was a mushroom-shaped flat-faced tuning post, with its top adjustable to make it possible to set the membrane-post distance; the membrane and the post formed a variable capacitor acting as a condenser microphone and providing amplitude modulation (AM), with parasitic frequency modulation (FM) for the re-radiated ...
Safety test. Hardware devices should always be tested if it is controlled by software which renders a microphone blocker useless. This can simply be done by plugging a headset or a microphone to the jack try to activate the internal microphone (eg with speaker mode on smartphones or feature phones and speak near the phone while keeping the microphone at distance or plugged), or any program ...
The Decca Tree setup evolved from the idea of a minimal recording technique using a pair of microphones. The first system was developed by Roy Wallace. The microphone triangle was placed about 3 to 3.6 m high above the stage level, near the conductor. The microphone system is not properly in front of the orchestra, but more "into" the orchestra.
