Audio Processing Core Algorithm:

Efficient and comprehensive algorithm is the basis of perfect sound quality, but also the crystallization of engineers' experience and wisdom. The built-in core algorithm is the soul of the processor.

AUTOMIXER

• Improve the transparency and clarity of speech;
• The feedback, reverberation and comb filtering effects are significantly reduced.
• Automatic adjustment, simplified Settings, plug and play;
• It can solve common problems such as insufficient gain before feedback and unclear speech.
• Each input channel has a dual-band equalizer.
• The adaptive noise threshold allows each input channel to distinguish between continuous background noise (such as air conditioning) and changing sound (such as voice), and constantly adjusts the channel activation threshold, so that the channel can only be activated when the voice volume is higher than the background noise;
• Lock the last mic until the next mic is activated, ensuring that background ambient sounds are present (without the last mic lock, a long pause in the conversation shuts down all the microphones, as if the audio signal is missing);
• Precisely control the priority of each microphone and lock down key speakers.

Automatic Echo Cancellation (AEC)

• Using subband algorithm, it has less MIPS consumption.
• The length of echo path can be set, the maximum echo off tail can be supported up to 512ms, suitable for all kinds of large, medium and small meeting rooms;
• Using the stable Double Talk detection method, it is effective even in the environment of strong background noise and nonlinear distortion, and the residual echo will not increase during the simultaneous speech of both sides.
• Strong robustness, can work in all possible applications and environments;
• The embedded noise suppression algorithm can eliminate the additional noise in the noise environment.
• The variable step size and post-processing algorithm greatly improve the rate of convergence and the echo rejection ratio (ERLE) of the nonlinear distortion of the terminal speaker.

​Automatic feedback elimination (AFC)

• Multi-point filtering and multi-subband frequency shifting keep the harmonic property of the original pitch period without causing sound distortion.
• Through acoustic modeling of room feedback path, the acoustic feedback can be eliminated adaptively.
• It can quickly track the feedback path changes and greatly enhance the ability to suppress the noise. The microphone transmission gain can be increased by 6-18db, greatly enhancing the microphone gain, suitable for various large, medium and small meeting rooms.

Automatic noise elimination (ANC)

• It is a noise suppression technique to deal with noisy speech signals.
• It decompositions the input signal into a series of frequency subbands, estimates the environmental noise and signal level in each subband, and then attenuates the subband signal according to the real-time SNR. The output signal is synthesized by smoothing and post-processing of these processed subband signals.
• Because of the unique post-processing algorithm, the noise suppression algorithm can track the environmental noise changes quickly and accurately while maintaining good output sound quality. Noise suppression reaches -30db, speech is almost completely distortion free.
