What is sound?
What we receive as sound is a sequential change of air pressure and in electronic, as a signal that is changing over time.
What does sound processing mean
Sound processing is one of the most important fields in technical science and engineering.
Sound processing is considered to be one of the most tangible (near to life) fields of engineering.
in this science, for example improving audio quality or increasing (strengthening) volume of voice as well as the human auditory system is the common goal of this type of process.

Audio Processing Applications
Some of the applications of voice processing and speech are in the following fields:
Phone networks and voice calls
recognition and production of human voice patterns
Save and maintain high - quality music
Play and write an audio file
Combine Sound (voice) signals
Create sound effects
stereo audio, is recorded by two separated sound sensors(microphones) this type of sound can actually have a proper estimation of the source direction,
human hearing is stereo!!!
In this figure the fictitious(Forgery) section of the sound is specified in the time - frequency domain.
Signal processing is a very broad branch of engineering science.
for example,In most cases, medical signals and telecommunication signal need signal processing
