DSP Algorithm

• Voice process

-Xear™ Volear Environment Noise Cancellation (ENC) HD technology for dual omni-microphones
-Adjustable 20-40dB cancellation of environmental dynamic and stationary noises and other parameters
-Supports a mic auto-calibration mechanism, allowing dual-mic sensitivity and mismatching in production
-Allows a wide placement distance range between two microphones (8-14 cm recommended)
-Supports mic-in auto-gain control (AGC) for ADC recording quality when the ENC HD function is on
-Acoustic Echo Cancellation (AEC) HD and Long Distance Recording (LDR) processing mode for speakerphones
-Mono-mic Noise Reduction (NR) HD processing mode for camcorder/voice recorders
-Up to 32KHz high-fidelity voice processing
