RTW – Eyes on Your Audio: RTW - Logging Data Server

The Logging Data Server license expands the feature set of your TouchMonitor with the Logging and Chart instruments (Loudness and SPL Display license (SW20002) required).

Logging and documentation of loudness measurements
Comprehensive analysis of the loudness course
Optional recalculation

The Logging instrument collects data of Loudness and TruePeak measurements of up to two audio groups of a preset and allows you to store it on a USB flash drive or to send it via IP connection to the free LQL - Loudness Quality Logger PC software for analyzing.

The Loudness Chart instrument is used for displaying and analyzing loudness measurement over time directly on TouchMonitors display.

If the Timecode Reader licence (SW20008) is enabled, loudness measurements can also be controlled via timecode, including the option of having it recalculated in case the same time span is measured repeatedly.

Logging

The Logging instrument is used to collect data of Loudness and TruePeak measurements of up to two audio groups and either to store them on a USB flash drive (upper example) or to send them via IP connection (lower example) to the LQL - Loudness Quality Logger (PC software available for free) for analyzing. The instrument allows two-stage definition of thresholds to indicate and to log the exceeding of limits set by legal or in-house regulations for example. If data cannot directly be stored on a USB flash drive or aquired by LQL, an enabled bargraph allows evaluation of the amount of temporary buffered data in the cache memory.

Specifications
Functions:			Logging of Loudness and TruePeak data of two audio groups Storing of data on USB flash drive or via IP with LQL - Loudness Quality Logger PC software Definition of main and secondary limits (individual markers) for Mmax, Smax, I and TPmax to monitor the adherence of e. g. legal regulations, current standards or in-house regulations Data collection control automatically via LQL (IP mode) or manually via control key (USB mode)
Mode:			selectable: off, USB, IP
Display:			Status display in the top line of the instrument placed on the screen: in IP mode: LQL access in USB mode: Disk space, running processes, storing if logging functionality is turned off
Identification for network:			Device name and password definable
Key function (USB):			USB run: Start logging USB close: Stops logging and creates a logfile on the USB flash drive

Chart

In the upper section, the Chart instrument displays the quality (e. g. exceedings) of the relevant loudness values TP, M, S, and I on horizontal bars with individual definable colors. In the lower section, the progress of a measurement (value over time) can be displayed on a coordinate system with up to four graphs. Therefore, different display options like time range or time select for evaluation are available. A dynamic line shows the position of the Relative Gate, and an additional bargraph for the display of the current I loudness value can be switched. If only one value is displayed, its graph can fully be filled with color (see image on the left).

Specifications
Functions:			Horizontal running bargraphs with individually definable colors evaluate the common quality of Loudness values TP, M, S, I Progress of a measurement (value over time) of up to four values can be drawn as graph(s) on a coordinate system Position of the Relative Gate switchable, color adjustable Adjustable time ranges Selectable time periods for evaluation Vertical Integrated bargraph switchable Tolerance levels and its display adjustable
Display:			Bargraph: Color change of the running bargraph indicates the section the loudness value is moving in: normal, operation range, Headroom, Over, invalid (availability depending on selected value) Chart graph: Continuously drawn graph (value over time) either of one value as line or rectangle with colored fi lling corresponding to the color selection of the horzontal bargraphs or of up to four values as line, dots, or rectangles without fi lling with individual color selection; added with Tolerance Indicator or position of Relative Gate (if selected)
Colors:			Bargraph: Individual selectable colors (32) for Normal (bargraph color), Operation Range, Headroom (TP only), TP Over (TP only), Over (M, S, I only), Invalid (M, S, I only) Chart graph: For each value individual selectable colors (32) for display modes without filling, otherwise adoption of corresponding bargraph colors, additional selectable colors for Tolerance Indicator and position of Relative Gate
Time Range:			Time grid adjustment for the coordinate system and the horizontal bargraphs: Increase or decrease of the preset time period in steps of one unit or ten units Magnification of the measured course to the available width of the instrument's window
Time Range presets:
- Auto stretch:			Automatic stretch of a stopped loudness measurement to the available width of the instrument's window, switchable (except when controlled via timecode)
- Hours:			0 h; adjustable from 0 to 3 h in steps of 1 h
- Minutes:			1 m; adjustable from 1 to 59 m in steps of 1 m
Time Select:			Selection of current time period (marker) Increase or decrease of the marker in step sizes corresponding to the current time grid Shift of the marker and magnification of the content
Tolerance Levels:
- TP Headroom:			-9.0 dB; adjustable from 0 to -20 dB in steps of 0.1 dB
- TP Operation:			0.0 dB; adjustable from 0 to -20 dB in steps of 0.1 dB
- M High:			+1.0 LU; M tolerance above Target Level adjustable from 0 to 10 LU in steps of 0.1 LU
- M Low:			-1.0 LU; M tolerance below Target Level adjustable from 0 to -12 LU in steps of 0.1 LU
- S High:			+1.0 LU; S tolerance above Target Level adjustable from 0 to 10 LU in steps of 0.1 LU
- S Low:			-1.0 LU; S tolerance below Target Level adjustable from 0 to -12 LU in steps of 0.1 LU
- I High:			+1.0 LU; I tolerance above Target Level adjustable from 0 to 10 LU in steps of 0.1 LU
- I Low:			-1.0 LU; I tolerance below Target Level adjustable from 0 to -12 LU in steps of 0.1 LU
