Since the introduction of broadcast loudness standards about a decade back, many new digital streaming platforms have appeared. And in recent years, the companies behind these new platforms have also started to recognise the need for recommending loudness specifications to its content providers.

Companies such as Spotify, Netflix, Apple, Sony, Amazon, Tidal and Google (YouTube) have their own loudness delivery guidelines – some are similar in terms of Integrated Loudness (LUFS) but may vary slightly with regard to True Peak (dBTP). Then again some are simply the same.

‘With so many different streaming services around, we saw a need for gathering all of the available information in one place so that content providers can get an easy overview,’ says Senior Director of Product Management, Mike Kahsnitz of RTW’s new online Global Loudness Delivery Guide. ‘For instance, if you make music and would like to submit your content to Spotify, Apple Music, Amazon Music, Tidal and Deezer, you should not just bounce one file for all of them. There simply is no one-size-fits-all solution.

‘There are also multiple standards in broadcast, depending on region, individual country and content type, we have found 35 different specifications that are all listed on our website – including the streaming platforms, we have nearly 50 instances, and it is our hope that content providers will see this as a helpful resource and may bookmark it as a future reference when delivering digital content. We are of course dedicated to maintain the list and update it in case specifications may change at some point, or when new ones arise in the future.’

The loudness delivery specifications provided on the RTW page all include Loudness and True Peak targets. Depending on content type and destination, parameters such as Short Term Loudness, Momentary Loudness and Max Loudness Range may also be included.
