DK-Technologies unveils MSD100C Loudness
DK-Technologies is launching the MSD100C Loudness, a loudness meter that is designed to tackle the issue of the perceived loudness of audio signals. There is no doubt that loudness is a hot topic for the broadcast and post-production industries. Sound processing can lead to remarkably high perceived sound levels without sound exceeding the maximum permitted signal peak levels.
DK-Technologies’ new MSD100C Loudness is a standalone unit that incorporates ITU Recommendations BS.1770 and BS.1771, which specify algorithms to measure audio program loudness. The unit displays the loudness of the individual audio channels, as well as the sum of the left and right signals, and can be used in any broadcast or post-production facility during production or prior to transmission.
The incorporated algorithm in the MSD100C Loudness is based on an extension of the Leq(RLB) algorithm to cover stereo and monophonic audio signals. The unit provides accurate loudness matching from a number of different sources and offers fast mode for real-time loudness viewing, 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 -18db to +9dB. It also features an audio vector oscilloscope, phase correlation meter displays, a full VGA color display and VGA output for external display.
Due to ship by the end of 2007, the MSD100C Loudness is available with a variety of language support and can be delivered with different scales to suit different broadcasters.
