Product details
miniDSP UMA-8 Multichannel USB Microphone
Note: This product comes with a coupon (€9,50) for one free miniDSP plugin download.
The UMA-8 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 on-board DSP processing, the UMA-8 supports voice algorithms including beamforming, noise reduction, acoustic echo cancellation and de-reverb. Non-technical users can enjoy a plug&play experience, while advanced users can fine-tune all DSP parameters with a real-time Win/Mac GUI for optimum performance. 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!
