Loudness Logging and Analyzing

Certain devices like the Kaleido-Solo are capable of monitoring the loudness of audio streams.
The data generated from monitoring may be sent to an Application Server where iControl’s
Loudness Logger can record and archive this stream of loudness data to a dedicated, external
drive.

After (or even during) the logging of loudness data, iControl’s Loudness Analyzer can plot a log
file’s loudness, making visible the data in units of LUFS (EBU) or LKFS (A85) over the time
period covered by the file. Loudness Analyzer allows you to zoom into the data plot as well,
effectively taking a subset of the time frame analyzed while increasing data granularity in the
chart.

Additionally, with Loudness Analyzer, you may edit analysis parameters as well as showing or
hiding certain data plots (e.g. choosing to show or hide the DIALNORM and Short-term
Momentary 1
data plots on the chart).

Log Database

Events and incidents in iControl can be recorded in a log database. If logging is enabled on an
Application Server, the GSM records detailed information, including timestamp, for
(potentially) every event in the system. The historical information in the database can help
track and identify problems. There is a unique log database for each GSM.

Loggers and Log Viewers

In iControl, a Log Viewer is a tool that is used to search and display the contents of a log
database. There are three types of Log Viewers:

Note: Logging loudness data necessarily involves an external drive in a NAS
(network attached storage) environment because loudness log files can grow rapidly
in size and number. The storage capacity of an Application Server is inadequate for
this purpose.

however, to turn off logging for individual alarms (see

Logging"
