UMA-16

[Michael]

Hi,

Can anyone share her/his results using Acoular with miniDSP UMA-16?

Which parameters such as sample rate and RectGrid did you use?

I'm getting funny results using:

• Frame rate: 44.1khz
• RectGrid(x_min=-0.5, x_max=0.5, y_min=0.5, y_max=0.5, z=0.3, increment=0.01)

Thanks

We've just started to try acoular on UMA-16. No result yet.

Besides the configuration provided, I think that you need the correct mic array geo-location file on the line:

micgeofile = path.join(path.split(acoular.__file__)[0],'xml','array_64.xml')

Yes indeed you have to use

micgeofile = path.join(path.split(acoular.__file__)[0],'xml','minidsp_uma16.xml')

For those interested in performing measurements with the UMA-16, one can now use the SpectAcoular repository, which uses Acoular for processing and provides a GUI (https://github.cAlso, seeacoular/spectacoular). 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 nanoSHARC (or any other input device). 

The app provides measurement and LiveBeamforming capabilities.
