Optimum loudness normalization for music streaming: Eelco Grimm, HKU University of the Arts and Grimm Audio)
Major pop music releases have suffered from the Loudness War for almost two decades. Now music streaming surpassed CD as major platform for music sales, there is a big opportunity to end this ‘war’, because the music of streaming services can be normalized in one central location. As soon as all music is played at an equal level, it makes no sense to issue loud masters anymore and the loudness war ends. Eelco Grimm cooperates with streaming service Tidal to design an optimal loudness leveling algorithm that does not harm the artistic intentions and opens the door to high sound quality for all major artists. He will present the results of his research into all 4.3 million albums of the Tidal database, plus a subject test. The project focuses on two questions: can album normalization also be used successfully outside the album context? And: which target level should be choosen?
Audio Guidelines for OTT TV and Video Streaming: Leslie Gaston-Bird, University of Colorado - AES administrator
Status of the collaborative work done within the AGOTTVS group chaired by Jim Starzynski (NBC Universal).
Strategies to stream broadcast contents on various platforms: Matthieu Parmentier, France TV – chairman of EBU Audio, co-chair of AES TC-Broadcast and Online Delivery
Production of broadcast contents is now fully constrained by loudness guidelines. Masters are usually aligned to –23 LUFS/-24 LKFS to feed either broadcast, broadband and streaming platforms. Due to the growth of mobile listening, where the overall dynamic needs to be reduced to face the background noise, several solutions arise and affect the The aim of this presentation is to present various strategies to allow the distribution of a same content on various networks and devices.
