    (term) XY

    XY creates a stereo image by using two cardioid or hyper cardioid microphones placed as near as possible to each other (and up to 12 inches apart) at 90-135 degrees spread and with the center of the spread pointed at the sound source.
  2. audiokid

    (term) M/S Mastering

    M-S Mastering The use of a middle (M) and a side (S) signal instead of the usual L/R (X/Y) signal can result in a much more selective and musical processing. The main reason for splitting the L & R stereo mix into M (sum of L and R) and S (the difference between L and R) is so that different...

    (term) Ms stereo

    The mid-side (M-S) stereo recording technique puts the center of the soundstage (mid) in one channel and the side information in the other. These mid and side channels can be adjusted and reconfigured to accurately represent a conventional left and right stereo image (on their own, they do...
  4. audiokid

    (term) Mono

    There is only one sound source or the signal was derived from one sound source.
  5. audiokid

    (term) Mic pad

    A device that reduces the level of the signal and is placed just before a microphone preamplifier to prevent overload of the preamplifier.
  6. audiokid

    (term) Low end

    A slang term for bass-frequency signals (below 250 Hz).
  7. audiokid

    (term) Level

    The amount of signal strength; the amplitude, especially the average amplitude.
  8. audiokid

    (term) Jack

    Commonly used audio connector. May be mono or stereo. The 1/4" jack is the oldest type of audio connector still in common use. It was first fitted to telephone exchanges over 150 years ago.
  9. audiokid

    (term) Expander

    A device designed to decrease the level of low level signals and increase the level of high level signals, thus increasing the dynamic range of the signal.
  10. audiokid

    (term) Exciter

    An enhancer that works by synthesizing new high frequency harmonics.
  11. audiokid

    (term) Electret microphone

    An electret microphone is a type of electrostatic capacitor-based microphone, which eliminates the need for a polarizing power supply by using a permanently charged material. Type of capacitor microphone utilizing a permanently charged capsule. A condenser microphone has a permanently polarized...
  12. audiokid

    (term) Close micing

    A technique of placing a microphone close to the sound source (within one foot) in order to pick up mainly the direct sound and to avoid picking up leakage or ambience.
  13. audiokid

    (term) Boom

    Boom: Extendable lightweight support pole for attaching a suspension device to hold the microphone. Principally used by the boom operator or sound recordist.
  14. audiokid

    (term) VO

    Voice-over (also known as off-camera or off-stage commentary) is a production technique where a non-diegetic voice is used in a radio, television, film, theatre, or other presentation.The voice-over may be spoken by someone who appears elsewhere in the production or by a specialist voice actor.
  15. audiokid

    (term) Comb-filter effect

    The frequency response caused by combining a sound with its delayed replica. The frequency response has a series of peaks and dips caused by phase interference. The peaks and dips resemble the teeth of a comb.
  16. audiokid

    (term) Attenuator

    In a mixer (or mixing console) input module, an adjustable resistive network that reduces the microphone signal level to prevent overloading of the input transformer and mic preamplifier.
  17. audiokid

    (term) Crossover

    An electrical device that divides the audio spectrum of a particular source into smaller groups of frequencies, making it easier for down stream components to handle the load. The most common use of crossovers is in amplifier/speaker systems, which allows the separate components to function...
  18. audiokid

    (term) CoreAudio

    Refers to the built-in audio capabilities of the Mac OS X. Similar to Sound Manager found in earlier Apple OS, CoreAudio deals with the way audio is handled within the computer and any application that is written specifically written to support it. Two of the major advantages that CoreAudio...
  19. audiokid

    (term) Contact Microphone

    A contact microphone receives its entire signal from being in contact with a particular surface and the resulting mechanical vibrations, not from airborne sound waves. Sometimes referred to as piezo or transducer microphones.
  20. audiokid

    Confidence Monitoring

    Listening directly from the recording medium while recording is in progress, thus ensuring the source material is being recorded correctly. Used in high-end analog recorders and DAT machines, a secondary head reads the recorded material immediately behind the record head. This allows the...
