Axon, a company which develops, manufactures and markets broadcast equipment for audio and video signals, has enhanced its TRACS compliance recording system with loudness logging and a monitoring option. This new feature will be on display at Axons stand (10.A21) at the International Broadcasting Convention, which takes place from 12 to 16 September in Amsterdam.

Jelle Wesseling, Axon s product manager for TRACS, says We have had numerous requests for loudness logging because of loudness regulations throughout the world.This new option in TRACS enables broadcasters to easily show their loudness control activities over time

According to the ITU-R BS.1770-3, EBU R128, ATSC A/8 or ARIB TR-B32 standards, this will enable monitoring and logging of loudness measurements of all audio channels on TRACS recorders (including existing installations) without additional hardware requirements.

During the real-time encoding process, before audio compression, all relevant audio loudness levels (up to 8 stereo pairs) are measured, driven by the advanced Emsytech Hummingbird loudness meters. Measurements are stored in the MPEG stream, for synchronized loudness monitoring, and in separate loudness data files for automated detection and retrieval.

During live play or playback of the recorded content, the momentary, short-term and integrated measurements are shown in audio bars, in sync with the video. The course of the loudness levels during a user defined period of time can be shown in a loudness history graph. This graph also shows a calculated integrated loudness level over the user defined period and can be exported to a .png, .pdf or .csv file.

Besides monitoring and logging, the TRACS loudness option also makes the compliance recorder function as an integrity checker for loudness levels. Loudness violations can be reported by means of emails or via SNMP statuses as well as visual statuses in the client.
