The high-definition hands-free solution of Sound+ Technology, enabling the audio conference call system to achieve high-definition call effect.
This solution can achieve the best performance in modern conference rooms, under the conditions of various distances and noise environments. This solution prominently solves such problems as room reverberation, linear and nonlinear echoes, and background noise, so that participants can obtain a high-quality duplex call experience at both ends of the call.

(High Dynamic) Multi-Channel Echo Canceller AEC
High Dynamic Multi-Channel Echo Cancellation supports echo cancellation of microphone arrays in loud volume, heavy bass situations.It can even realize non-linear noise residual suppression in audio at 100dB and solve the pain point of AEC performance degradation when the microphone and loud speakers are close to each other. It combines DNN units to accurately judge the echo components, and after echo cancellation, it preserves clear near-end speech components. It supports full duplex calls.

Noise Reduction
Noise reduction is the process of removing noise from a signal,it can detect and suppress stationary , non-stationary and transient noise.Stationary noise including air conditioners, projectors, non-stationary including background human voices,Transient noise including keyboard clack and doorbells,etc.
-
Adaptive Beam forming
Sound+ multi-channel beam forming Algorithm adaptively locates the direction of speech signals in the setting range with array of two or more microphones ,for enhancing user’s voice and better suppress environmental noise and room reverberation.
-
Deep neural network processing unit
The parameters of DNN are obtained through multiple iterations of training, and tens of thousands of hours of training data are specially designed to accurately separate background noise in complex acoustic environments. DNN can provide advanced automatic gain control, echo and reverberation cancellation, and dynamic noise suppression functions.
-
Multi-band EQ
Multi-band EQ Adjusts output frequency response of microphone and speaker to meet customer’s needs.
-
Automatic Volume Control – AGC, DRC
AGC enables output signal amplitude to be adjusted to the desired loudness. The Sound+ AGC module can dynamically adjust the output signal range, making the volume range of the entire audio signal more balanced, providing a more stable and comfortable auditory experience.
