  2. Microphone - Wikipedia

    en.wikipedia.org/wiki/Microphone

    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 ...

  3. Sound Recorder (Windows) - Wikipedia

    en.wikipedia.org/wiki/Sound_Recorder_(Windows)

    Before Windows 7, Sound Recorder could save the recorded audio in waveform audio (.wav) container files.Sound Recorder could also open and play existing .wav files. To successfully open compressed .wav files in Sound Recorder, the audio codec used by the file must be installed in the Audio Compression Manager (ACM); Windows installations dating back to at least Windows 95 came with a selection ...

  4. Line level - Wikipedia

    en.wikipedia.org/wiki/Line_level

    Line out provides an audio signal output and line in receives a signal input. The line in/out connections on consumer-oriented audio equipment are typically unbalanced, with a 3.5 mm (0.14 inch, but commonly called "eighth inch") 3-conductor TRS minijack connector providing ground, left channel, and right channel, or stereo RCA jacks.

  5. Measurement microphone calibration - Wikipedia

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

    Sound calibrators are used in an identical way to pistonphones, providing a known sound pressure field in a cavity to which a test microphone is coupled. Sound calibrators are different from pistonphones in that they work electronically and use a low-impedance (electrodynamic) source to yield a high degree of volume independent operation.

  7. Laser microphone - Wikipedia

    en.wikipedia.org/wiki/Laser_microphone

    The technique of using a light beam to remotely record sound probably originated with Léon Theremin in the Soviet Union at or before 1947, when he developed and used the Buran eavesdropping system. [1] This worked by using a low power infrared beam (not a laser) from a distance to detect the sound vibrations in the glass windows.

  8. Noise-canceling microphone - Wikipedia

    en.wikipedia.org/wiki/Noise-canceling_microphone

    Sound that's much closer to the front port than to the rear will make more of a pressure gradient between the front and back of the diaphragm, causing it to move more. The microphone's proximity effect is adjusted so that flat frequency response is achieved for sound sources very close to the front of the mic – typically 1 to 3 cm. Sounds ...

  9. Human microphone - Wikipedia

    en.wikipedia.org/wiki/Human_microphone

    A human microphone, also known as the people's microphone, is a means for delivering a speech to a large group of people, wherein persons gathered around the speaker repeat what the speaker says, thus "amplifying" the voice of the speaker without the need for amplification equipment. The speaker begins by saying "mic check".
