Analysis of Multi-Segment Loudness Logs
Depending on the type of device used to log loudness data (upstream of your Application Server), you may or may not have segment-specific information multiplexed with the loudness data. If the loudness data in your log file consists of many segments (perhaps hundreds), you may wish to generate a multi-segment report over a span of time of your choosing. iControl allows you to do this.
If your loudness log file consists of segments, you may wish to view analysis data with clear demarcations between segments, along with the display of other segment-specific meta-data. This is possible if segment information is included with the loudness data by the source logging device. Alternatively, it is also possible if segment information is available as an external As‑Run log file.
An As‑Run log file is a text-based file. There are variations in As‑Run file types, but these differ from one another only in format and organization of information. Regardless of the file type chosen, all As‑Run log files are equivalent in function, that being to allow Audio Loudness Analyzer to map the As‑Run file’s segment times (and other meta-data) to discrete chunks of loudness data. This effectively allows Audio Loudness Analyzer to analyze, display, and report loudness data with segment-level granularity.
