TECHNOLOGY FOCUS Loudness Metering
These technologies stand out as some of the best solutions in the myriad of loudness control solutions now available.
The DaySequerra iLC2ST offers real-time adaptive loudness control of two independent TV channels. As with other DaySequerra loudness control and monitoring units, it offers credible audio quality via DTS Neural processing and is loudness compliant with EBU R128, ATSC A/85 CALM, and ARIB-B32. The iLC2ST is 1U high so it doesn’t take up much space in your rack and a dual DSP platform allows it to make gain corrections imperceptible. It has GPI-
switched user presets, perfect for changing the depth of the loudness control used, depending on the content or at particular times of the day. The iLC2ST also has an Ethernet port and is supplied with free Windows remote dashboard software for remote control and logging. With AES/EBU digital audio I/O as standard, there are options for analogue audio I/O and the HD-SDI embedded audio.

Conforming to all major international broadcast delivery standards and recommendations for loudness and peak level, the TSL PAM PiCo is now available in three models, all with loudness logging as standard. The PAM PiCo offers seven user programmable operational views in landscape and portrait modes with common standard features
such as the starfish and jellyfish surround sound displays, true-peak level, FFT spectrum analyser, SMPTE timecode reader, Eyeheight measurement, and the 5.1 bargraph and histogram modes. A free PC-based loudness logging application is available for use with all PAM PiCo models. The logging application delivers a highly effective yet cost-efficient means to record, analyse, and archive real-time loudness and true peak level history. Via a PC connected to the PiCo over USB the logging application writes all key
loudness and peak measurement parameters to a database in real time while displaying a graphical analysis of each reading against time enabling instant recognition of signal behaviour. PDF or CSV log files can be extracted from the database to create both graphical and spreadsheet reports
for archive purposes or as a validation of loudness and peak for a given commercial or TV show. It is purposely designed for use across the entire broadcast facility from ingest to post production, acquisition to transmission. Furthermore, because the device is self- contained and requires only power and media to function, it covers a range of alternative applications from television production to music recording and gaming.

The DK-Technologies DK T7 is a complete audio, loudness, and logging system addressing the key measuring and reporting needs of any broadcast, post, or music engineer. It combines high-precision metering with a detailed logging and reporting system – all included in a single ‘no frills’ package. The metering tools collection offers bar graphs, classic moving coil emulations alongside the StarFish stereo and multichannel phase and level meter, as well as clear text read-outs and detailed spectrum analysing. DK T7 includes detailed real-time logging of key loudness and true peak parameters, allowing for detailed review and reporting of any audio event at any point in time. The multi-touch user interface makes the operation quick and instant when setting up metering of the 3G SDI-, AES-, and analogue inputs and outputs. The user interface allows for a high level of customisation, ranging from the detailed choice of metering tools, to the specific functionality of the on-screen custom buttons. The compact and fan-less hardware design allows the DK T7 to be mounted table-top, 19in rack, and even as a flush mount console integration.

The Dolby DP580 is the first Dolby TrueHD reference decoder, providing features that enable monitoring, display, and logging of all audio-related metadata and measurement of program loudness, using Dolby Dialogue Intelligence, Leq (A), ITU- R BS.1770-1, ITU-R BS.1770-2, or EBU mode loudness estimation. It also provides detailed analysis of Dolby audio streams for professionals, making it ideal for broadcast trials and manufacturers’ test environments. Designed to help broadcasters monitor streams along multiple points of the broadcast chain, the DP580 serves all Dolby audio codecs, including Dolby Digital, Dolby Digital Plus, HE AAC with Dolby metadata, Dolby E, and Dolby Pro Logic II technologies. Enhanced
features of Dolby Digital Plus, such as secondary audio bitstream mixing and 7.1- channel decoding, can easily be monitored using the DP580. This is in addition to a real-time reference tool for generating signals for Dolby TrueHD, Dolby Digital, and Dolby Digital Plus. It enables validation of associated Dolby TrueHD signals encoded in the Metadata-Enhanced Audio Transmission (MAT) format, a type of validation that has not previously been available in any testing environment. All of these features enable consumer and professional device manufacturers to use the DP580 to test the integration of Dolby technologies in their products.
