Log file format and structure
Each log file is a plain text file with the structure
shown below. The header shows a summary of
the log, followed by the actual, time-stamped
values in tab-separated values format.
This file format can easily be imported into
spreadsheet applications such as Microsoft Ex-
cel or Apple Numbers for further analysis.
Log file header
If the Loudness Meter preset being used has
been edited, the Preset Name is followed by “Ed-
ited”. The serial number, preset name and soft-
ware version information for the logged device is
also available.
The summary includes statistics, and the mea-
surements are stored every second.
Time and date is added while dumping the log
file. This information is derived from the com-
puter that the TC Icon software is running on.
Accordingly, you need to ensure that the com-
puter’s clock is set correctly.
Log file name
The log file’s name is composed from the Algo-
rithm, the Device ID, the Meter Engine, the date
(coming from the computer running the TC Icon
software), plus a number starting with 0000 and
increased for each log file retrieval on the same
date.
Log file example
Header lines are indicated by a leading hash
character.

Working with log files
You can delete, move and rename log files as
required using Windows Explorer in Microsoft
Windows, the Finder in OSX or a third-party file
manager.
Auto Logging
Using the free TC Icon software application (but
not the hardware TC Icon), it is possible to spec-
ify a fixed interval at which the computer will col-
lect Loudness Meter log files from the Frames
controlled by the Icon software.
Log file retrieval can be activated for a wide
range of TC Electronic devices from TC Icon
software.
