Right off the bat, you need to know that the applications is designed for those who have at least the basic knowledge and understanding of what it means to run an analysis of this type. You get this idea from the start, by observing the interface. Everything is well organized, and even the graphics say 'this is all technical'.
The application is designed to be a complete solution for just about any situation where you need to measure sound signal magnitude, frequency range and spectrum power.
Spectrum Analyzer pro Live offers you the possibility to encode MP3 to WAV and vice-versa, normalize Wave files and split the stereo signal into two mono files. These probably being the easiest tools to understand when opening the application for the first time.
You can use Spectrum Analyzer pro Live as a mobile instrument to measure and then calibrate the acoustics for chambers, speakers and microphones. With its 'Sound Check' feature, you can run frequency response measurements using both provided and custom audio samples, thus saving time when it comes to performing sound checks for concerts.
The 'Compare' function, enables you to simultaneously measure the input and output between line levels. Spectrum Analyzer pro Live also provides you with an MP3 / Wav player that you can use to detect modifications in the sample rate.
On a descriptive note, the application allows you to change the display mode of the analyzer between bars, peaks, scroll, lines and vertical lines, as well as choose between stereo and mono analysis methods. You are also able to customize the outfit of the spectrum, its decay and draw scale.
Apart from some small interface glitches now and then, and the fact that the spectrum freezes when you access the upper menus of the application, you can't really say that Spectrum Analyzer pro Live has shortcomings. But then again, you can only judge it's capabilities in practical situations.
