From microphone array input to clean voice output

The audio engine is built as a full processing chain: capture speech, understand the acoustic scene, reduce interference, then deliver a cleaner and more natural voice to the far end.

01

AI Noise Reduction

Suppresses steady noise and non-stationary sounds such as keyboards, knocks and office activity while preserving the speech body.

02

AI Dereverberation

Reduces room tail and hard-surface reflections so remote listeners hear a more forward and intelligible voice.

03

AI Echo Cancellation

Controls speaker echo returning into the microphone path, reducing feedback, echo and double-talk interruptions.

04

32kHz Pickup

Preserves more voice detail and high-frequency information for far-field meetings and voice interaction.

05

DOA Localization

Estimates speaker direction from the microphone array and provides angle data for camera linkage and multi-device coordination.

06

Smart Audio Curtain

Limits pickup to 60, 90 or 120 degree sectors to emphasize target speech and reduce off-axis interference.

07

ASR Enhancement

Optimizes front-end speech for meeting minutes, live captions and voice commands in noisy or far-field environments.

08

3A and Full Duplex

AEC, ANS, AGC and full-duplex voice keep conversations natural even when both sides speak at the same time.

Product-ready audio processing chain

Input

Array Pickup

Captures far-field speech, background noise, speaker playback and room reflections from 4-mic, 8-mic or larger arrays.

Understanding

AI Scene Modeling

Identifies speech, noise type, echo path, speaker direction and target pickup area before enhancement.

Enhancement

Speech Cleanup

Noise reduction, echo cancellation, dereverberation, beamforming and gain control work together on the captured voice.

Output

Conference Voice

Delivers clearer voice to conferencing, recording, ASR or real-time communication systems.

Audio Demos

Use the demo clips to compare how the front-end algorithms handle echo, reverberation, noise and voice clarity.

AI Noise Reduction

Compare untreated meeting noise with the processed speech output.

AI Dereverberation

Reduce room tail and hard-surface reflection while keeping speech more forward.

AI Echo Cancellation

Control loudspeaker return and double-talk interruption in a conferencing path.

High-Sampling Pickup

Hear the voice detail retained by the high-sampling far-field pickup path.

Technology Matrix

Audio functions can be combined according to device form factor, microphone count and target application.
