Many types of input transducers can be found in a sound reinforcement system, with microphones being the most commonly used input device. Microphones can be classified according to their method of transduction, polar pattern or their functional application. Most microphones used in sound reinforcement are either dynamic or condenser microphones.
The H2 Digital Handy Recorder H2 in use as a USB audio input device H2 and H4 with 10 eurocents for scale. The H2 Handy Recorder is a handheld digital audio recorder from Zoom first announced at the NAMM Show in February 2007. It records very high quality digital stereo or 4-channel audio on a hand-held unit, and has been called "the studio on ...
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 two main classes of sound recording technology are analog recording and digital recording .
Their high output impedance matched the high input impedance (typically about 10 MΩ) of the vacuum tube input stage well. They were difficult to match to early transistor equipment and were quickly supplanted by dynamic microphones for a time, and later small electret condenser devices. The high impedance of the crystal microphone made it very ...
The dynamic range of an audio system is a measure of the difference between the smallest and largest amplitude values that can be represented in a medium. Digital and analog differ in both the methods of transfer and storage, as well as the behavior exhibited by the systems due to these methods.
The electroacoustic mechanism most widely used in speakers to convert the electric current to sound waves is the dynamic or electrodynamic driver, invented in 1925 by Edward W. Kellogg and Chester W. Rice, which creates sound with a coil of wire called a voice coil suspended between the poles of a magnet.
An audio format is a medium for sound recording and reproduction.The term is applied to both the physical recording media and the recording formats of the audio content—in computer science it is often limited to the audio file format, but its wider use usually refers to the physical method used to store the data.
Sound is produced in the larynx. But producing the sound would not be possible without a power source: the flow of air from the lungs. This flow sets the vocal folds into motion to produce sound. [10] Breathing for singing and speaking is a more controlled process than is the ordinary breathing used for sustaining life.
