Spectrum analyzers are widely used for audios, whether analog or digital. Sound as one of the basic reasons why there are further complications in electronics and science in general, the researches and studies on spectrum analyzers will never put to halt but will continue to get improved.

Sound is considered an energy disturbance perceived by our basic hearing sense- the ears. Before it gets through as the audio sound we hear, the whole unseen proponents involving the journey of a sound has been studied in intangible form as a wave with frequency as one of its properties analyzed by audio spectrum analyzer.

When it comes to dealing with audio spectrum analyzer, they usually come in two parallel methods: analog (traditional) and digital (computerized). Although there is nothing new with the word digital, it is important to understand the difference in dealing with analog audio and digital audio before trying to grasp understanding its analysis. To differentiate, try to think of an analog clock with hands versus a digital clock showing time in numbers.

Digital sound is the by-product of mathematical processes, which computers can perceive easily through binary computations. The conversion of this data is what could be seen as graphs in any high level (user friendly) applications commonly used even in personal computers.

When the world started to shift to the use of computers, the drastic change paved way to complex improvement in audio spectrum analysis. The possibilities of having better access to impossibilities are solved by what varying software can do. Programmers who are specializing in developing spectrum analyzer can transform dynamic computations and algorithms automatically through formula. Creating a system can be expanded to visual advantage.

Usually it takes a company to create a team concentrating on this, and the software become available through the web as shareware, betas, and full versions software, which can be bought at lower cost. In this case, it is already emphasized that unless one clings to traditional analog way of spectrum analysis, there is advantage in using the aid of computers.

No matter where the subject on audio spectrum analysis go it still goes back to the root- sound. Sound is part of our living and there are many reasons why spectrum analyzers are needed on a daily basis. It involves all the people in the field of science, medicine, engineers, manufacturers, researchers, companies, scientists, and students. It has opened up multiple horizons for those who are strictly confined to audio analysis.
