Description
The UMA-8-SP is a high-performance USB microphone array paired with a digital audio amplifier. Seven high-performance MEMS microphones are configured in a circular arrangement to provide high-quality voice capture in farfield microphone applications such as AI assistants, conferencing, robotics…
Leveraging the onboard DSP processing from XMOS XVSM3000, the UMA-8-SP supports voice algorithms including beamforming, noise reduction, acoustic echo cancellation and de-reverb. The UMA-8-SP is a fully compliant UAC2 audio interface with driverless support for Mac/Linux and ASIO drivers for Windows. An onboard 2x15Wrms digital amplifier provides an all-in-one microphone array + amplifier integration. The perfect fit to build your own AI assistant or conferencing unit.
From DIYers to OEM, this pocket-size platform is engineered for flexibility in firmware, software and hardware. Feel free to contact miniDSP on how we can help kickstart your new project!
