A pistonphone is an acoustical calibrator (sound source) that uses a closed coupling volume to generate a precise sound pressure for the calibration of measurement microphones. The principle relies on a piston mechanically driven to move at a specified cyclic rate, pushing on a fixed volume of air to which the microphone under test is coupled.
The changing pressure deforms the granules, causing the contact area between each pair of adjacent granules to change, and this causes the electrical resistance of the mass of granules to change. The changes in resistance cause a corresponding change in the current flowing through the microphone, producing the electrical signal.
The Victoria voice was enhanced significantly in Mac OS X v10.3, and added as Vicki (Victoria was not removed). Its size was almost 20 times greater, because of the higher-quality diphone samples used. A new, much more natural-sounding voice, called "Alex" has been added to the Mac text-to-speech roster with the release of Mac OS X 10.5 Leopard ...

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 ...
