Zooming into Audio Loudness Analyzer’s Data Plot

Logs > Detailed Directions > Working with Loudness Logger and Audio Loudness Analyzer > Zooming into Audio Loudness Analyzer’s Data Plot

After loading a loudness data file into Audio Loudness Analyzer, the plot of the loudness data may not show, by default, the granularity of detail you might like to see at first. Additionally, the time period covered by the data may cover too large a time span.

You can effectively zoom into the data by specifying a subset time period within the initial graph, thereby increasing granularity and removing extraneous data.


NOTE: You may choose to either configure analysis parameters before you zoom or after you zoom with the same end-effect. You will lose analysis parameter data ONLY when you click Default Analysis.
