BVE 2013: Jünger Audio readies latest loudness processor
The newest addition to Jünger Audio’s range of audio loudness processors, M*AP, will be on show at BVE later this month. In conjunction with UK distributor Aspen Media, the company will demonstrate the processor, which combines an audio monitor conroller and a loudness measurement device in one unit.
Designed for quality checking surround (5.1) and/or stereo content, M*AP can be used for live monitoring and also to ensure compliance with today’s standards and regulations (ITU 1770/1/2/3, ATSC A85 or EBU R128).
The unit comes with alarm signals that alert the operator when pre-set loudness thresholds are exceeded, and these signals can be delivered by simple GPOs and/or SNMP traps, which carry actual loudness values. Loudness measurements can be performed over a long run or over a fraction of a program, or both. These measurements can be triggered by automation systems via GPIs or via the network – or even manually by buttons of the X*AP remote panel.
Alongside loudness measurements, M*AP offers functionality for acoustical QA. It has an option for up to eight speaker outputs that allow for monitoring of the audio mix and A/B checking of stereo compatibility of a surround downmix through alternative speakers, as well as via L/R front speakers.
Peter Pörs, managing director of Jünger Audio, says: “By incorporating 3G, HD and SD auto detection, M*AP gives users the option of dealing with all 16 channels of SDI embedded audio at the same time. This means that you can listen to one program while permanently logging the loudness of two (5.1 +2 mode) or four (4×2 mode) programs. It is also possible to send further de-embedded programs to M*AP’s AES outputs to feed a third party instrument for analyzing and/or display.”
For no extra cost, the M*AP’s SDI board acts as an embedder as well and comes with video delay to compensate for any kind of audio delay. M*AP also features a built-in Dolby Metadata generator and an optional Dolby decoder that allows users to decode Dolby-E, Dolby-D (AC-3) and Dolby Digital plus (E-AC-3). Optional Dolby Metadata emulation will be introduced in the second quarter of 2013.
Jünger Audio will also be showing the Award-winning T*AP TV Audio Processor and Loudness Logger at BVE 2013.
