We have an internal ticket that has been created. In the meantime, you can do something similar to this:
This will let you run the C++ library from the
However, this lead to another issue on our side when we noticed that the live classification results and the inference results given by the C++ SDK are not the same when have multiple spectrogram dsp blocks.
@rjames is still investigating on the second issue and we will let you know as soon as we have more details.
Thanks for reporting this issue.
