Hi-Fi Audio Quality

48 kHz full-band audio sampling, dual-channel stereo and voice positioning realizes 3D surround-sound stereo experience.

Low-Latency and Low-Freezing

Global E2E maintains about a 70ms latency range, ensuing smooth and stable audio calls even if uplink and downlink network packet loss reaches 70%.

AI Echo Cancellation

Echo cancellation based on neural network algorithms ensures clear audio calls.

AI Background Noise Reduction

Noise reduction based on neural network algorithms mitigates disruptions.

AI Audio Restoration

Extract high-frequency audios and restore audios with higher quality based on neutral network algorithms.

Flexible Open APIs

Developer-friendly A/V pre-processing supports easy access to A/V databases, meeting customization demands like voice change, beautification and AR.
