  3. Professional audio - Wikipedia

    en.wikipedia.org/wiki/Professional_audio

    A professional audio store is a retail establishment that sells, and in many cases rents, expensive, high-end sound recording equipment (microphones, audio mixers, digital audio recorders, speakers and surround sound speakers, monitor speakers) and sound reinforcement system gear (e.g., speaker enclosure cabinets, stage monitor speakers, power ...

  4. Balanced audio - Wikipedia

    en.wikipedia.org/wiki/Balanced_audio

    Balanced audio is a method of interconnecting audio equipment using balanced interfaces. This type of connection is very important in sound recording and production because it allows the use of long cables while reducing susceptibility to external noise caused by electromagnetic interference. The balanced interface guarantees that induced noise ...

  5. Wireless microphone - Wikipedia

    en.wikipedia.org/wiki/Wireless_microphone

    A wireless microphone, or cordless microphone, is a microphone without a physical cable connecting it directly to the sound recording or amplifying equipment with which it is associated. Also known as a radio microphone , it has a small, battery-powered radio transmitter in the microphone body, which transmits the audio signal from the ...

  6. Joint encoding - Wikipedia

    en.wikipedia.org/wiki/Joint_encoding

    Intensity stereo coding. This form of joint stereo uses a technique known as joint frequency encoding, which functions on the principle of sound localization. Human hearing is predominantly less acute at perceiving the direction of certain audio frequencies. By exploiting this characteristic, intensity stereo coding can reduce the data rate of ...

  7. Measurement microphone calibration - Wikipedia

    en.wikipedia.org/wiki/Measurement_microphone...

    A pistonphone is an acoustical calibrator (sound source) that uses a closed coupling volume to generate a precise sound pressure for the calibration of measurement microphones. The principle relies on a piston mechanically driven to move at a specified cyclic rate, pushing on a fixed volume of air to which the microphone under test is coupled.

  9. Balanced line - Wikipedia

    en.wikipedia.org/wiki/Balanced_line

    In telecommunications and professional audio, a balanced line or balanced signal pair is an electrical circuit consisting of two conductors of the same type, both of which have equal impedances along their lengths, to ground, and to other circuits. [1] The primary advantage of the balanced line format is good rejection of common-mode noise and ...
