For example, if a solo instrument within an orchestra needs an extra mic for added volume and presence, placing the mic too close would result in a pickup that sounds overly present, unnatural and out of context with the distant, overall orchestral pickup. To avoid this pitfall, a compromise in distance may be struck.
An example of a nondirectional microphone is the round ... the reflections from that surface have the same timing as the direct sound, thus giving the microphone a ...
Two examples of different boundary mics (top) and a diagram of the elements of a boundary microphone. The diagram shows the location of the mic capsule, the plate, the aperture, and the pressure zone. In 1978, audio engineers Ed Long and Ron Wickersham studied the effects of the boundary layer in sound recording.
A parabolic microphone is a microphone that uses a parabolic reflector to collect and focus sound waves onto a transducer, in much the same way that a parabolic antenna (e.g. satellite dish) does with radio waves. Though they lack high fidelity, parabolic microphones have great sensitivity to sounds coming from one direction, along the axis of ...
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.

Block diagram of the signal-flow for a common feedback loop [1]: 118 . Audio feedback (also known as acoustic feedback, simply as feedback) is a positive feedback situation that may occur when an acoustic path exists between an audio output (for example, a loudspeaker) and its audio input (for example, a microphone or guitar pickup).
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 ...
An example of a microphone splitter. Let's begin by tracing the signal path from the splitter to the audience. The signal leaves the splitter, typically via an Audio multicore cable, and travels to the Front of House position. Here, the still-mic-level signal enters into a microphone preamplifier, which boosts the signal voltage to line level.
