Professional audio application is commonly used to denote professional audio and engineering activities, which may include but is not limited to radio broadcasts, audio mastering, sound reinforcement such as a concert, DJ performances, Audio Sampling, a public statement, surround sound cinema, and in some cases use piped music.

Both terms imply participation of audio equipment in the industry (professional) level, but not personally. For example, the regular use of personal microphones such as the mobile phone will have very limited dynamic range focus on the words, the sake of audio microphone will have a much wider dynamic range to capture the quiet whispers or loud musical instruments. A regular loudspeakers for home use can handle 100 W rms signal to noise ratio, while pro-audio loudspeakers such as one used for the concert can also be seen 1000 watts rms or more, or in the studio, he can use the act to a much more effective signal to noise rating on the same 100 watts, as a speaker at home.

Specifications alone does not include or exclude equipment to be dealt with as professional audio level, but are used in most publications and documents as a starting point.
