Noise cancellation is not supported in P2P or Go rooms.You can only run one audio track through the audio plugin pipeline per Participant.Noise cancellation will increase CPU load on a device, as all the preprocessing happens on the device.In this case, you will get audioTrack with audioTrack.noiseCancellation set to null. If you try to use Krisp noise cancellation on a browser that is not supported, the SDK will return a non-Krisp enabled track to the application and your audio will follow the standard audio pipeline. The table below lists the minimum browser version across major browsers: It also requires browser support of the WebAudio API (specifically Worklet.addModule). Twilio Video Noise Cancellation requires you to host and serve the Krisp audio plugin for Twilio as part of your web application. Note that all of these steps happen on your device, with almost no latency, and no media sent to a server. During this step, the AI-based noise cancellation algorithm removes unwanted sounds like barking dogs, construction noises, honking horns, and coffee shop chatter.Īfter the preprocessing step, the audio is encoded and delivered to the end user. The plugin needs to be loaded alongside the Twilio SDK and runs as part of the audio pipeline between the microphone and audio encoder in a preprocessing step. It’s with this technology that we created the Krisp Audio Plugin for Twilio Video, a lightweight audio processor that can run inside your client application and create crystal clear audio. Using tens of thousands of hours of audio recordings, Krisp.ai has created a sophisticated Deep Neural Network that can differentiate between background sounds and the human voice. This feature is available for all customers using Twilio Video Group Rooms. Twilio has partnered with Krisp Technologies Inc., a leading technology vendor for noise suppression, in order to provide Twilio customers a best-in-class audio experience. You can remove hundreds of unwanted types of background noises from a video room using the Krisp Audio Plugin for Twilio Video to power AI based noise cancellation.
