Copenhagen, Denmark (December 3, 2007)–The issue of loudness has plagued the broadcast audio industry for some time now. DK-Technologies have introduced a new tool to tackle the issue, the MSD100C Loudness, a standalone meter.
DK-Technologies is launching the new MSD100C Loudness in response to requests from key broadcasters and production houses, including SKY, ITV, the BBC and RAI in Italy. The standalone unit incorporates ITU Recommendations BS.1770 and BS.1771, which specify the algorithms that should be used to measure audio program loudness. It is able to display 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 as a health check during production or prior to transmission.
Thomas Hansen, DK’s technical director, says, “There are many applications where it is necessary to measure and control the perceived loudness of audio signals. Examples of this include television and radio broadcast applications, where the nature and content of the program material changes frequently. In these applications the audio content can continually switch between music, speech, and sound effects.
“Such changes in the content of the program material can result in significant changes in subjective loudness. Moreover, various forms of dynamic processing are frequently applied to the signals, which can have significant effect on its perceived loudness.”
Hansen adds that the matter of subjective loudness is also of great importance to the music industry and in the production of commercials, where dynamic processing is commonly used to maximize the perceived loudness.
Due to ship by the end of the year, the MSD100C Loudness is available of a variety of languages and can be delivered with different scales to suit different broadcasters, while still maintaining the consistent loudness measurement as set out by the ITU.
