Highlights of Fixed Architecture DSP Beidou

The use of ADI high-performance chip:

BeiDou series all adopt ADI SHARC 21489@450 MHz SIMD processor chip, which can be better for the internal algorithm and DSP work processing.

Bus type AEC function:

Bus AEC algorithm, eliminating the tail for a long time can be as high as 512ms, and echo convergence rate can be done to 60dB/S, echo elimination amplitude of 60dB, to meet the majority of the hall building acoustics is not good and there is a large reflection of the sound case, do the echo elimination of teleconferencing issues.

Built-in USB sound card interface:

Beidou series are built-in USB sound card interface, can be accessed through the interface to the computer, automatic recognition of the sound card, computer audio playback or audio recording. At the same time can also be accessed through the interface to the computer for remote video conferencing audio function options.
