A-B Stereo is a recording technique. For this you have to use two identical omnidirectional microphones placed some distance apart. A-B stereo microphone technique is often used when the sound source is wide and/or when the distance from the microphones to the source is significant or become somehow relevant in that process of recording.
The calibration microphone is that mic used for measurement rather than recording purposes. These types of microphones usually have a flat response because the main idea is to have a accurate and also uncolored picture of audio source.
Analog to Digital Converter (or simply put ADC, A/D or A to D) is that device which transforms analog audio signals into digital form / data. The reverse operation of this process is made by a Digital to Analog Converter (DAC). An Analog to Digital Converter is one of the most used devices in today music production industry since the computers are the core of today recording and production studios. Once converted into a digital form, digital audio signals can be processed in a lot of ways, the only limit being the software and the actual music production software solutions can reach the sky.
Digital Audio Tape or simply put, DAT, is a signal recording and playback standard medium. DAT was developed by Sony and introduced in 1987. Digital Audio Tape has become the standard recording and archiving technology in professional recording environments for master recordings. The technology is based on video recorders and the 4 mm tape and also the rotary head configuration is closely similar to 8 mm from Sony.
In music production field, term “recording” refers to that process of translating information or capturing audio data to a recording format. The data is stored on a storage medium named record or sometimes “recording”.
44100 or 44.100 hz or 44,100 hz or 44.1 kHz is the most common sampling frequency or sampling rate used because it is the sampling rate of the Compact Discs (CDs). Analog audio signal is recorded by sampling ub 44.1 kHz or 44,100 times per second and the samples reconstruct audio signal on playback. “Hz” is the abbreviation for hertz meaning, roughly said, samples pe second.
Bitrate, sometimes written bit rate or data rate represents the number of bits processed pe unit of time. Bitrate is quantified as the bits per second or bps, usual in a conjunction with a metric prefix (kilo, mega, giga, tera). 1kilobit per second (1kbit/s) is defined as 1000 bit/s not 1024 bit/s as iti is in the most of other related computer units.
