Standard WebRTC echo cancellation mechanisms are available as a default in the Amazon Chime SDK, but customers can opt to upgrade to Amazon Chime SDK’s state-of-the-art ML-based echo reduction for improved voice quality, especially during double-talk situations when multiple virtual meeting participants are speaking at the same time. Noise reduction uses ML to help reduce environmental noises like wind, fans, and running water, background noises like lawn mowers and dogs barking, and foreground noises like keyboard typing and shuffling papers.Įcho reduction is designed to reduce disruptive acoustic echoes that can happen in a virtual meeting when the sound played by a participant’s loudspeaker is picked up by their own microphone and recirculated back into the meeting. Messaging, media pipelines, speech enhancement, and PSTN audio capabilities are also available with pay-for-use pricing.Īmazon Chime SDK offers machine-learning (ML) based speech enhancement capabilities including noise reduction using Amazon Voice Focus and echo reduction. A WebRTC media session can be replicated to up to 40 additional WebRTC media sessions, providing media distribution to a further 10,000 participants. A single WebRTC media session supports up to 250 participants, however you can reach more participants with media replication. Developers using WebRTC media can choose to implement some or all of the available media modalities (audio, video, and screen share) for a single rate.
The Amazon Chime SDK offers pay-for-use pricing with no upfront fees. Visit the AWS Service Region Table for the list of available regions. The Amazon Chime SDK elastically scales to your applications needs, and allows your application to place WebRTC media sessions in other AWS regions. You can simplify operations, and build these features without managing real-time communication infrastructure services. The Amazon Chime SDK allows you to add real-time audio, video, screen sharing, and messaging capabilities to your applications.
