AudioMedia - March 2009 - (Page 47) The actual unit provides accurate loudness matching of audio from a number of different sources and offers a selection of working modes, including a Gated mode for viewing loudness of audio material with long pauses. With selectable digital and analogue stereo inputs, the MSD100C Loudness displays left and right channel loudness, as well as the summed loudness, and the information is also available as a numeric readout. The meter uses the Loudness Units (LU) scale, covering a range from -18db to +9dB, and features an audio vector oscilloscope, phase correlation meter displays, a full VGA colour display, and VGA output. channel analogue and digital, multi-channel Dolby Digital and Dolby E, and in-the-clear analogue. It has a software remote control that allows for extended logging and enhanced analysis via a computer. The unit comes in two configurations; the LM100-LTC, which can log to external timecode, and the LM100-NTSC, which additionally measures NTSC CATV and off-air signals. OB vehicles, the PAM1-3G8 is a valuable tool for ingest and quality control, and anywhere space is at a premium. www.tsl.co.uk Sonoris’ Meter VST K-metering plug-in can measure peak and loudness levels of audio signals simultaneously, and present the results on a single scale. Along with standard loudness monitoring, the plug-in also supports the K-System developed by Bob Katz, Mastering Engineer and founder of Digido mastering studio. Sonoris’ Meter closely follows the K-system specifications, including the Leq (A) loudness metering and band limited pink noise monitor calibration. The software features an over-sampling peak meter mode which catches intersample peaks that can cause ear fatigue when using low headroom D to A converters as found in most consumer CD players. The software features a correlation meter that www.dolby.com www.dk-technologies.com Dolby’s LM100 Broadcast Loudness Meter is a 1-U rackmount unit designed to measure the subjective loudness of programme dialogue and presents the results in a numerical format, eliminating the variations in results when interpreting traditional VU or PPM indicators. Dolby’s device is designed for network centres, satellite facilities, cable head-end facilities, turnaround uplinks, programme ingest facilities, quality control, and post production; and now features the BCAP recommended ITU-R BS 1770/1 algorithms in addition to the Leq (A) measurement algorithm. The LM100 has multiple inputs that accept two- TSL claims that its PAM1-3G8 provides ‘Everything in 1 Rack Unit’, with respect to compact audio monitoring solutions. It features dual 3Gbps SDI video inputs, Dolby E decoding, and high quality internal loudspeakers. The unit can simultaneously displays eight bargraphs of decoded audio, Dolby metadata, and BCAP standard ITU BS 1770 and BS 1771 loudness measurement using a pair of high resolution OLED displays.
