Error when trying to use measurement app

[Marcel]

Hi,

I tried using the Measurement App (https://acoular.github.io/spectacoular/apps/measurementapp.html) that is included in the SpectAcoular extension. I have a UMA16 MicArray connected so I tried to start the app using "bokeh serve --show Measurement_App --args --device=sounddevice --blocksize=256" in the Anaconda Prompt, but I'm getting the following error: https://pastebin.com/HpuyEmSR

Any advice on what to do?

Thanks

Hi Marcel,

the error indicates that the class "SoundDeviceSamplesGenerator" is missing. SpectAcoular relies on the SoundDeviceSamplesGenerator class from the Acoular package (http://acoular.org/api_ref/generated/generated/acoular.sdinput.SoundDeviceSamplesGenerator.html#acoular.sdinput.SoundDeviceSamplesGenerator). However, the class is only available in both packages if the python-sounddevice library is installed (which is optional). If the library is already installed, the error might come from a too old version of Acoular, which does not yet include the class. Which version of Acoular do you use? 

Best,

Adam

It's working now, I downloaded the package from git and copied the whole thing into the lib directory of anaconda and started it from there. I probably tried to start the app from the false directory before.
