Hi

I’m trying to use blks2.analysis_filterbank. I assume that I need to

instantiate it like this:

self.channeliser = blks2.analysis_filterbank(num_fft,taps)

where num_fft refers to the number of channels and taps can be left

empty.

I tried self.channeliser = blks2,analysis_filterbank(16) (and 8 and

20). None of these work. I get the following error:

terminate called after throwing an instance of ‘std::out_of_range’

what(): gri_fftw: invalid fft_size

Aborted

Does anyone know what’s wrong? If I get it to work, do I just connect

each output path that I’m interested in to a block, similar to when

using a mixer in the fm examples?

Thanks a lot.
