DynamicRangeAnalyzer

Audio files come with a variety of characteristics, which musicians take into account when recording and bundling all waves into a readable audio file. Analysing an audio file doesn’t necessarily have to involve music. For instance, DynamicRangeAnalyzer is a tool which can read frequencies, display a dynamic range graph, and overall decibels.

Note that the application is built to run on different types of machines because it completely relies on Java Runtime Environment to function. Moreover, there’s no setup involved so you can just store it on a USB flash drive to be carried wherever needed. It doesn’t edit any registry entries so the target PC’s health status remains intact.

The process takes only little time from start to end. Running the application brings up a load dialog so you can select the MP3 file to be analyzed. Another method of triggering the core function is to simply drop an MP3 file over the executable, saving you a bit of time.

Once loaded, the application starts to analyze audio frequencies in real time. A cool effect is created as the file is read and the graph gradually builds up until the final form. Graph coordinates represent amplitude and length, with intuitive path lines. Apart from the graph itself a new window shows up to inform you of the overall level of decibels.

When you view all details and confirm the small prompt the application closes. A neat trick to instantly launch it from any location is to assign a hotkey command to its shortcut from the properties panel. The only downside to the whole operation is that you can’t save the graph to file.

Taking everything into consideration, we can state that DynamicRangeAnalyzer is sure to provide the DNR results from analyzing any MP3 file on the spot. The graph neatly builds to show amplitude levels in time, while portability equips it with a great deal of flexibility, making it worth a try overall.
