The aim of these products is to address loudness control at different stages of content creation and distribution so that broadcast customers can easily ensure loudness compliance. On show at NAB 2018 (booth C3039), the enhanced version of LA Production incorporates various new features, including the ability to work as a Windows service. This latest version also utilizes the original adaptive Level Magic algorithm that allows broadcasters to comply with all current international loudness standards while preserving a high audio quality.
The system normalizes files with a multi-stage design and as a result the audio is compliant with a selected standard but free of any unwanted artefacts such as pumping, breathing or distortion. The application works in automatic and manual modes. In auto mode, files from a watch folder are analyzed and normalized if necessary. A frame-accurate video player and audio channel mapping option can be named among other useful features of LA Production.
LA Production features certified loudness normalization using Tecom Group’s algorithm or Jünger Audio's Level Magic advanced Loudness Management, with automatic file-based loudness analysis and normalization, fully supporting watched folders. The solution offers audio channel mapping for measurement and normalization of multichannel audio, and features customizable threshold values and settings. LA Production supports loudness measurement according to all international loudness standards based on ITU-R BS.1770 (all revisions), including EBU R128, ATSC A/85, ARIB TR-B32, FREE TV OP-59 and Portaria 354, with chart view presentation of short-term and momentary loudness and automatic generation of detailed measurement reports (excel format. The integrated video player allows frame-by-frame analyzation of all loudness values. File support includes .MXF, .AVI, .MOV, .MP4, .FLV, .MPG video formats and for .WAV audio.
Tecom Group has also announced that its LA Playout loudness analyzer now integrates with Imagine Communications’ D-Series playout automation system, in addition to the ADC playout automation, and that both LA Playout and LA Production have dark (professional) skins.
