![]() Different operating loudness values is why the AES Broadcast and Online Delivery Technical Committee put forth updated recommendations in TD1008. ![]() Clearly, this is a challenging spread when audio is played on shared devices. Many distributors of audiovisual or audio-only content are now using loudness normalization, but with different targets. Fortunately, these services are adopting moderate loudness targets not only to help match music and other content, but to help provide more headroom to improve dynamic quality. On-demand music services distribute mostly popular commercial music, which are still driven by album production styles with very high integrated loudness. Online video services, known as “Over the Top Television” (OTT) quickly became a major form of distribution and have adopted guidelines based on the recommendations documented as ANSI A/85, EBU R128 and AES71, and in some cases with customization to help support wide-dynamic range content and viewing on mobile devices. The leading standards, listed in AES71 specify a similar 24 or 23 LUFS (or LKFS) target for both production and distribution to consumers. This was driven by viewer complaints of loud commercial content. The focus of this website is loudness for online audio content, but in discussion of target levels would not be complete without so some mention of other multimedia services.īroadcast television began using integrated loudness (or average dialogue loudness) and normalization of audio worldwide in the 2005-2010 time frame.
