Echo cancellation mitigated this problem. During the call setup and negotiation period, both modems send a series of unique tones and then listen for them to return through the phone system. They measure the total delay time, then configure a delay line for that same period. Once the connection is completed, they send their signals into the ...
Situational circumstances: Sometimes a microphone should not be visible, or having a microphone nearby is not appropriate. In scenes for a movie the microphone may be held above, out of the picture frame. Processing: If the signal is destined to be heavily processed, or mixed down, a different type of input may be required.
ORTF setup. 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).
The microphone consisted of four amplifiers, for different powering schemes, and about 20 capsules, for different directional patterns and/or frequency response characteristics (any capsule of the series is compatible with any of the amplifiers). This was the first type of microphone to let the user separate the capsule from the amplifier (body ...
The position of the pop filter is different in different recording situations, with a further position from the microphone causing fewer pop sounds. More distance means increasing the microphone gain and gaining more room noise. Normally, to get good quality, the pop filter should be placed about 2–6 inches (5–15 cm) away from the ...
Kingston began manufacturing removable disk drive storage products in 1989 in their Kingston Storage Products Division. By 2000, it was decided to spin off the product line and become a sister company, StorCase Technology, Inc. [9] StorCase ceased operations in 2006 after selling the designs and rights to manufacture its products to competitor CRU-DataPort.
Spill occurs when sound is detected by a microphone not intended to pick it up (for example, the vocals being detected by the microphone for the guitar). [3] Spill is often undesirable in popular music recording, [4] as the combined signals during the mix process can cause phase cancellation and may cause difficulty in processing individual tracks.

The charged elements in the vacuum tubes can mechanically vibrate, changing the distance between the elements, producing charge flows in and out of the tube in a manner identical to a capacitor microphone. A system sufficiently susceptible to microphonics could experience audio feedback, and make noises if jarred or bumped.
