Whois & Analysis for performanceaudio.com

Professional audio, occasionally abbreviated as pro audio, refers to both an activity and a type of high quality audio equipment.

Typically it encompasses sound recording, sound reinforcement system setup and mixing, and studio music production by trained sound engineers, audio engineers and audio technicians who work in live event support, using audio mixers or sound reinforcement systems.

In contrast, consumer audio equipment is usually confined to the reproduction of sound in a private home on a home stereo or home cinema system.

A guitar amplifier (or guitar amp) is an electronic amplifier that strengthens the weak electrical signal from a pickup on an electric guitar, bass guitar, or acoustic guitar so that it can produce sound through one or more loudspeakers, which are typically housed in a wooden cabinet.

A guitar amplifier may be a standalone wood or metal cabinet that contains only the power amplifier (and preamplifier) circuits, requiring the use of a separate speaker cabinet–or it may be a "combo" amplifier, which contains both the amplifier and one or more speakers in a wooden cabinet.

There is a wide range of sizes and power ratings for guitar amplifiers, from small, lightweight "practice amplifiers" with a single 8" speaker to heavy combo amps with four 10" speakers and a powerful amplifier, which are loud enough to use in a nightclub or bar performance.

Sound recording and reproduction is an 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.

Prior to the development of analog recording, there were mechanical systems for recording instrumental music, such as wind-up music boxes and later, in the late 19th century, player pianos.

Audio equipment refers to devices that reproduce, record, or process sound.

This includes microphones, radio receivers, AV receivers, CD players, tape recorders, amplifiers, mixing consoles, effects units, and loudspeakers.

In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a transmission medium such as air or water.

In physiology and psychology, sound is the reception of such waves and their perception by the brain.

Humans can hear sound waves with frequencies between about 20 Hz and 20 kHz.

Sound above 20 kHz is ultrasound and below 20 Hz is infrasound.

Other animals have different hearing ranges.
