AMPLITUDE
The strength or power of a wave signal.The "hight" of a wave when viewed as a graph. Higher amplitudes are interpreted as a higher volume , hence the name "amplifier" for a device which increases amplitude.

//A video is may contain only visual data but Footage contains both Audio & visual data.

sound wave properties
*How many types of sound wave ?
//All waves have certain properties. The three most important once for audio work are shown here:
1.Wavelenght, 2.Amplitude,3.Frequency

what is audio
what is audio ?
//Audio means ''of sound''or"of the reproduction of sound ".Specifically,it refers to the range of frequencies detectable by the human ear - approximately 20 Hz. Its not a bad idea to memories those numbers -those numbers-20 Hz is the lowest-pitched (bassiest) sound we can hear,20 KHz is the highest pitch we can hear.

what is sound wave
what is sound of wave ?
//A sound of wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or any other liquid or solid matter) as it propagates away from the source of the sound.
The idea that sound moves in waves goes back (at least) to about 240 B.C The philosopher Chrysippus (c.240 B.C),The Roman architect & engineer Vetuvius(c.25B.C)& the Roman Philosopher Boethius(A.D.480-524)each theorized that sound movement might take a wave form
