acoular with mems microphone arrays

[François Hernandez]

Hi all,

I just found out about acoular and was wondering if this could be well suited to handle data from mems microphone arrays like Matrix Creator/Voice, ReSpeaker or MiniDSP's UMA-8. Has anyone already tried any of this?

Thanks in advance!

I am starting on this now.  A Respeaker 6 mic attached to raspberry pi.  If anyone wants to work jointly on this please respond.

I am starting with acoular with ReSpeaker Mic Array v2.0 also attached to a rasberry pi. I wouldnt mind working jointly.

Hey JT, I’m also using a respeaker array. Have you had any luck getting acoular to work with it? Would greatly appreciate your input.

For those interested in performing measurements with a plugged sound device, such as the ReSpeaker Mic Array, one can use the SpectAcoular repository, which uses Acoular for processing and provides a GUI (SpectAcoular Repo). See Documentation on how to start the application.

The app uses the python-sounddevice package which provides access to audio streams available by the PortAudio library. Simply do

bokeh serve --show Measurement_App --args --device=sounddevice --blocksize=256 ,

which will open the browser with the application window. There one can select the corresponding device. 

The app provides measurement capabilities. Live beamforming is possible if the microphone geometry is provided via .XML file.
