In far-field detection, a microphone recording of the victim is played as a test segment on a hands-free phone. [30] On the other hand, cut-and-paste involves faking the requested sentence from a text-dependent system. [11] Text-dependent speaker verification can be used to defend against replay-based attacks.

When the Decision Review System (DRS) was introduced to test cricket, initially Snicko was not considered accurate enough, and so another edge detecting tool Hot Spot was used. In 2013, an improved Snicko called the Real Time Snickometer, which was more reliable and faster to use, was used for first time for DRS in the 2013-14 Ashes series .
Central to the Livescribe platform is the smartpen, a ballpoint pen with an embedded computer and digital audio recorder. When used with Anoto digital paper, it records what it writes for later uploading to a computer, and synchronizes those notes with any audio it has recorded. This allows users to replay portions of a recording by tapping on ...
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.
Frances Densmore and Blackfoot chief Mountain Chief working on a recording project of the Bureau of American Ethnology (1916).. Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects.
The microphone's output is usually low-pass filtered. [25] [28] A simple surround microphone configuration involves the use of a front array in combination with two backward-facing omnidirectional room microphones placed about 10–15 meters away from the front array. If echoes are notable, the front array can be delayed appropriately.
