The sound system operator can use equalization to change the frequency response of a microphone or loudspeakers system to increase GBF. The frequency which first begins ringing or feeding back is identified by the operator, and a notch or parametric filter is engaged to reduce the overall level of that frequency. [ 3 ]
The proximity effect in audio is an increase in bass or low frequency response when a sound source is close to a directional or cardioid microphone. [1] [2] Proximity effect is a change in the frequency response of a directional pattern microphone that results in an emphasis on lower frequencies. It is caused by the use of ports to create ...
Feedback can be reduced manually by ringing out a sound system prior to a performance. The sound engineer can increase the level of a microphone until feedback occurs. The engineer can then attenuate the relevant frequency on an equalizer preventing feedback at that frequency but allowing sufficient volume at other frequencies.
In close miking, a microphone is placed relatively close to an instrument or sound source, within three to twelve inches, producing a dry or non-reverberant sound. [1] This serves to reduce extraneous noise, including room reverberation and is commonly used when attempting to record a number of separate instruments while keeping the signals ...
A microphone, colloquially called a mic (/ m aɪ k /), [1] or mike, [a] is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones , hearing aids , public address systems for concert halls and public events, motion picture production, live and recorded audio engineering , sound ...

A microphone is a transducer and as such is the source of much of the coloration of an audio mix. Most audio engineers would assert that a microphone preamplifier also affects the sound quality of an audio mix [citation needed]. A preamplifier might load the microphone with low impedance, forcing the microphone to work harder and so change its ...
