OUR ADVANTAGES

Algorithms and Services

Acoustic Echo Cancellation

(AEC)

AEC algorithm was designed to eliminate echo, reverberation, and unwanted added sounds, which is needed when a far end signal is played over a loudspeaker into a reverberant acoustic space and is picked up by a microphone.

Widely used in video conferencing applications such as Teams, Zoom, Google Meet etc.

Feedback Suppression

(AFS)

AFS algorithm monitors incoming audio for signs of feedback, when it detects feedback behavior, it places a narrow notch filter at each frequency that feeds back, reducing the gain of that frequency.

Used in the signal path in a live sound reinforcement system to suppress audio feedback.

Noise Suppression

(ANS)

ANS algorithm provides a feature to suppress the effect of noise in a speech signal. This function is useful for microphone based applications that have a potential for incoming speech corruption from ambient noise, removes steady state noise.
