Video-based reflection is a reflective practice technique in which video recordings, rather than one's own memory, is used as a basis for reflection and professional growth. Video-based reflection is used with moderations in various professional fields, e.g. in the field of education and pedagogy .
It is also possible to vary the pattern continuously with some microphones, for example, the Røde NT2000 or CAD M179. There are two main categories of condenser microphones, depending on the method of extracting the audio signal from the transducer: DC-biased microphones, and radio frequency (RF) or high frequency (HF) condenser microphones.
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).
The boundary microphone can be used as a piano mic by placing it inside the piano lid, an approach which can obtain better pickup of the piano's mix of sharp percussive transients and gentle undertones than other microphone options. Boundary mics are used on hockey boards for body check sound effects. They are also commonly used to record full ...
A laser microphone is a surveillance device that uses a laser beam to detect sound vibrations in a distant object. It can be used to eavesdrop with minimal chance of exposure. It can be used to eavesdrop with minimal chance of exposure.
Parabolic microphone used at an American college football game. 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 ...
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 ...
Instrumental use of microphones has been developed by many experimental composers, musicians and sound artists. They use microphones in unconventional ways, for example by preparing them with objects, moving them around or using contact microphones to colour the sound and be able to amplify otherwise very silent sounds.
