The Twilio Voice JS SDK now offers Audio Processor APIs, enabling developers to access raw audio input and modify it before sending it to Twilio. This feature allows for client-side noise cancellation use cases and other audio modifications, such as injecting music playback or applying custom filters. The new feature is designed to improve call quality by reducing background noise and enhancing speech clarity. It is integrated with Krisp.ai's technology, which uses a Deep Neural Network to differentiate between background sounds and human voice. The integration allows developers to create crystal-clear audio experiences without sending media to servers, with minimal latency.
