Thank you for choosing the UMA-16 audio processor board. The UMA-16 is a cost effective sixteen-channel
microphone array with plug-and-play USB audio connectivity. With its embedded XMOS interface, the UMA-16 is
the perfect fit for researchers looking to develop their own beam forming algorithms.
The UMA-16 system architecture is powered by two core elements:
-
A microphone array PCB with 16 x SPH1668LM4H MEMS Knowles with PDM outputs. A center hole fits an
optional USB camera perfect in applications such as acoustic cameras. The microphone array is a simple 2-
layer design that can easily be customized to your needs by following our schematics included in this user
manual.
-
Stacked on top of the mic array is the MCHStreamer Lite USB interface. This XMOS XCORE multicore CPU
allows for a high quality PDM to PCM conversion and presents all 16 channels of raw audio to the ASIO USB
audio driver.
Please note that the following sections will highlight basic operation of the UMA-16. Beamforming algorithm
development or any 3
rd
party support for software (e.g. Matlab) is considered outside the scope of this manual
and our support structure.
