(click thumbnail)DK-Technologies will premier its MSD100C Loudness meter, which it says is designed to tackle the issue of the perceived loudness of audio signals.
MSD100C Loudness is a stand-alone unit that incorporates ITU Recommendations BS.1770 and BS.1771, which specify the algorithms that should be used to measure audio program loudness. It displays the loudness of the individual audio channels, as well as the sum of the left and right signals, and can be used in broadcast or post-production facilities as a “health check” during production or prior to transmission.
MSD100C Loudness incorporates an algorithm based on an extension of the Leq(RLB) algorithm to cover stereo and monophonic audio signals. The unit provides loudness matching of audio from a number of sources, and offers a selection of working modes, including Fast mode for real-time viewing of loudness; Integrated mode for measuring the loudness of a recorded section or the complete recording; and Gated mode for viewing loudness of audio material with long pauses.
With selectable digital and analog stereo inputs, the MSD100C Loudness displays left and right channel loudness as well as the summed loudness. It also delivers the information as a numeric readout. The meter uses the Loudness Units (LU) scale, covering a range from –18 dB to +9 dB. It also features an audio vector oscilloscope, phase correlation meter displays, a VGA color display and VGA output for external display.
