Far Field Mic Array Solution
The DSR-0703 is a high-performance yet low cost multichannel USB microphone array built around RK3308 (Rockchip), with improved adaptive beamformer, AEC and barge-in, noise suppression, AGC. Two high-performance MEMS microphones are configured in a linear arrangement to provide high-quality voice capture for a wide range of applications. Leveraging high performance Quar Core A53 processing, the DSR-0703 supports voice algorithms including beamforming, noise reduction, acoustic echo cancellation and de-reverb. The DSR-0703 is a fully compliant UAC2 audio interface with driverless support for Mac/Linux and ASIO drivers for Windows.
