Audio signals or sound waves travel through air are longitudinal waves. i.e. the waves consisting of condensation and rarefaction of air partials. The unit of audio singles are bels or decibels or early radio broadcasting audio processing was compulsory due to many problems incurring, in transmitting links with the studios. Before the advent of digital audio processing the analog signal processing in use. Something which is mathematically soon by a set of continuous values a good example of analog system is the continuously moving hands of a clock directly changing the information that the clocks is providing. Analog signals processing was in use before the invention of digital processing as it was only way to manipulate a signal. Digital signals are pressures based forming a seduces of symbols mostly binary no in nature permitting signal processing through digital likes micro process and computers. Though such conversion is likely to lose yet most modern audio system use this approach being more powerful and efficient as compared with analog signal processing The eld where digital signal processing system methods and application can be use are storage level compression, data compression, transmission, enhancement (equalization, filtering, knows, cancellation echo or reverb removal or addition etc). Audio Broadcasting: Just before transmitting audio processing takes place in studio is limited in modern studios. Because of digital audio system (mixtures, router) being pervasive. The audio processor in case of audio broadcasting must check over modulation and minimize when it happens. Compensate for non linear transmitting commonly occurs with medium wave and short wave broadcasting. Loudness is adjusted according to the desired level and errors erupting in audio level in also corrected. Unprocessed audio signal is called dry why the processed audio signal is called wet. The technique use for the same are: Echo, angar, phaser, chorus, equalization, littering, overdrive, pitch shift, time, stretching resonators, robotic voice, synthesizermodulation compression 3 D audio effect, reverse echo, active noise control wave field synthesis. On the whole digital signal system helps a lot in the field of communication, business, education etc.
