    miniDSP UMA-16

    miniDSP UMA-16


    16 channels Low cost USB microphone array, Uniform Rectangular Array (URA), 16 x raw audio ASIO driver, perfect for a DIY acoustic camera, USB to PDM interface for up to 16 x MEMS



    UMA-16 is a high-performance yet low cost 16 channel USB microphone array with plug&play USB audio connectivity. With its onboard SHARC+XMOS controller board, the UMA-16 is the perfect fit for development of beamforming algorithms or DIY acoustic camera. Its system architecture consists of two core elements:

    The microphone array PCB has 16 x SPH1668LM4H MEMS Knowles laid out in a Uniform Rectangular Array (URA). A center hole fits an optional USB camera for applications such as an acoustic camera. Being a simple 2layer PCN, one can easily customize his own array layout by following our schematics.

    At the helm of the UMA-16 operation is the nanoSharc kit. A 400MHz SHARC ADSP21489 + 500MHz multicore CPU providing substantial processing power for high SNR PDM to PCM conversion and multichannel low latency USB audio.The UMA-16 can also be used as a low cost USB to PDM mems board to acquire and convert audio for 3rd party MEMS.

    With the UMA-16, miniDSP makes high channel count microphone array processing very affordable and hopes to further technological advances for beamforming technology.
