miniDSP Introduces UMA-8 USB Microphone Array

Kowloon Bay, Hong Kong, May 17, 2017 (Newswire.com) - 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 onboard 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 realtime 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.

For advanced users, full control and configuration of the DSP array processing parameters are available with a real-time GUI. This can be used to fine-tune the various algorithms: acoustic echo cancellation, noise reduction, voice activation detect, and so on. With its USB API for direction of arrival, 8ch raw audio mode via USB Audio, PDM to I2S conversion, this tiny module offers a level of flexibility that engineers will certainly enjoy!

Step by step application notes are now available for setup and configuration of the UMA-8 with the most common smart assistants currently available:

• UMA-8 setup with Amazon Alexa Voice + Raspberry Pi
• UMA-8 setup with Microsoft Cortana
• UMA-8 setup with Apple Siri

The UMA-8 is now available at 95USD/pc on miniDSP's webshop. For more details on the user manual and product datasheet. Stay tuned for some exciting app notes!
