The Amazon Chime SDK now supports Amazon Voice Focus, the same noise suppression technology that powers Alexa Communications and the Amazon Chime application, to improve the sound quality and reduce unwanted background noise. Amazon Voice Focus uses deep learning to reduce environment noises like wind, fans, and running water; background noises like lawn mowers and dogs barking; and foreground noises like keyboard typing and shuffling papers. Developers can choose how and when Amazon Voice Focus is active in their applications using the Amazon Chime SDK for Javascript, iOS, and Android.
The Amazon Chime SDK for Javascript SDK now supports 48kHz audio capture and playback. Most Bluetooth headsets only capture 16kHz audio which works well for many situations, including meetings, that focus mostly on voice capture. However, many USB and built-in microphones support a higher audio capture of 44.1kHz or 48kHz. For developers building an application that captures live instruments or pre-recorded musical content, the 48kHz sample rate and configurable encoding bitrate capture the full human perceivable range of audio frequencies for crisp and clear sound quality.
On the video side, you can now analyze and modify video from your application clients before it is encoded in a session. Client-side video inspection and manipulation gives you read-write access to each video frame, so you can add features such as auto-framing on the user; background blurring or replacement; count the number of users; and apply a watermark or embed a logo. Client-side video inspection and manipulation is available in the Amazon Chime SDKs for Javascript, iOS, and Android.
The Amazon Chime SDK lets developers add real-time audio, video, and screen sharing capabilities to their own web or mobile applications. To learn more about the Amazon Chime SDK, review the following resources:
