Platform upgrades dramatically increase scale and capacity has increased scale for its ultra-low delay audio streaming product to meet the needs of the growing social audio application space. Businesses and developers can now take an interactive conversation with up to 16 presenters and stream it to 5000 listeners with a delay of less than 500ms. The low streaming delay means that the audience can react quickly to the presenters with chat and seamlessly transition from listener to presenter.


The audio streaming service takes advantage of Dolby's expertise in audio capture, accomplishing superior quality even across a wide range of devices. With easy-to-use SDKs, developers can quickly integrate powerful capabilities such as noise suppression, echo suppression, real time communications, and even spatial audio that separates voices and provides better intelligibility despite overlapping speech.


This expanded capacity for audio streaming complements the scale improvements for ultra-low delay video streaming announced in July, when released support for up to 3000 listeners. Dolby will continue to look for ways to improve the platform in terms of scale, capacity, and resiliency, ensuring the offerings continually meet customer needs.

We can't wait to hear - and see - what they build."

New software development tools address industry-wide media challenges

Today Dolby also adds new APIs to the platform: Media Transcode and Music Mastering. These APIs are designed to address specific business challenges in delivering high-quality audio and video content, at scale.

Transcode API

Every piece of content viewed on the internet, whether a film, podcast, music video, or social media clip, is transcoded prior to publishing.
