G-Audio Loudness SDK Provides Consistent Streaming Listening Experience  

G-Audio has developed new software for developers that equalizes variations in loudness and provides continuity of perceived sound levels for consumers using OTT video and music streaming platforms. The new software, called the Sol Loudness SDK, for XR and streaming media, helps increase subscriber satisfaction and improve content retention.

Naver Corporation, a South Korea-based Internet content service company, is one of the first companies to integrate the Sol Loudness SDK for their streaming media services

“With 62% of U.S. adults streaming TV and movies each week, streaming services have revolutionized the way consumers listen to and watch media,” said Alexis Macklin, Analyst at Greenlight Insights. “Unfortunately, this mass appeal has yet to translate to consistent audio quality. The streaming market is set to be disrupted by new solutions focused on setting higher standards in streaming audio quality. Loudness management will be central to the features that creators and publishers will need to deliver as a growing number of consumers expect consistent audio quality across streaming platforms.”

G-Audio’s SDK product line includes spatial audio rendering for 360-degree video and loudness management for streaming media. Other loudness management software solutions today employ a legacy file-based approach, which is a pre-processing pipeline that destructively modifies the original content. The Sol Loudness SDK uses a server-client architecture in which the server-side performs loudness measurement and generates metadata that the client-side uses to normalize content to the target loudness setting.

Advantages to the server-client solution include, (1) the opportunity to set loudness targets per platform, end-user device, or even listening environment, and (2) the original content is never modified, avoiding compression artifacts.
