The Dolby difference

Dolby has revolutionized the science of sight and sound through innovative research and engineering. Your users can experience Dolby-quality sound in your apps through the power of Dolby Voice®. Dolby Voice® is an award-winning audio communications technology backed by decades of expertise in sound signal processing.

Reliable and scalable

Our network resilience and random loss distribution capabilities help to maintain audio quality between users even in the most challenging network conditions. Our mixing solution processes over 15 billion minutes annually with conference providers such as BlueJeans and British Telecom.

Secure and compliant

From encryption and security certification to our commitment to a secure environment, Dolby.io delivers a communication service that you can trust. Dolby.io is GDPR, HIPAA, and SOC-2 compliant.

We’re excited to bring the magic of Dolby.io to help retailers create top quality CitNOW videos for their customers, even in loud environments.

Having really powerful audio cleaning, equalization and audio enhancement technology is something no one else in the industry is offering, which has really set us apart from the pack.

Dolby.io allows our users to save time and maximize their creative possibilities in post-production.

Building the same solution on our own would have taken two years, as opposed to just two months with Dolby.io.

Because of Dolby.io, our users can use our platform to quickly clean up podcasts, webinars, or other audio with just a click of a button.

Dolby.io’s client SDKs and UI kits were easy to implement and put on our devices—both mobile and web.

The intimate magic of audio, as a medium, only happens when the physical distance melts away, and podcast hosts and guests feel like they’re in the same room. Dolby.io helps us dissolve the distance of remote recording.

It’s never just about technology, it’s how you interact with it. With Dolby.io, our telehealth platform provides healthcare customers the ability to communicate with patients… all while delivering millions of crystal-clear call minutes.
