The UMA-8 v2 is a high-performance yet low cost multichannel USB microphone array built around XMOS multicore technology. Seven high-performance MEMS microphones are configured in a circular arrangement to provide high-quality voice capture for a wide range of applications. Leveraging the onboard DSP processing, the UMA-8 supports voice algorithms including beamforming, noise reduction, acoustic echo cancellation and de-reverb. The UMA-8 is a fully compliant UAC2 audio interface with driverless support for Mac/Linux and ASIO drivers for Windows.

From DIYers to OEM, this pocket-size platform is engineered for flexibility in firmware, software and hardware. Precompiled firmware versions, expansion connectors providing connectivity for additional PDM microphones, I2S in/out expansion and GPIO... It’s all there to grow with your application!

NEW: The UMA8 rev2 is now sporting the latest chipset from XMOS Vocal fusion series (XVF3000) with improved adaptive beamformer, full duplex AEC and barge-in, noise suppression, AGC. This new version provides major improvement to the DSP mode. Note however that the control GUI doesn't operate at this time for the DSP mode. We will work in the coming weeks to bring similar control GUI interface for the XVF3000. Stay tuned!

STOCK UPDATE (05/07/2018): The UMA8 is now back in stock. All shipments will resume today. Thanks for all your patience!
