Whoops, yeah, that's right, I'll change that in the next iteration.

Thanks for the output! Could it be that you are using the old RFC patch with 
the new fft-eval? I've added another byte (max_exp), so the header became 
longer. Please try again with the latest patch (from this thread), if that is 
the case. Otherwise we have to find out whats wrong ... The sample_len as used 
in fft_eval (tlv-header + data) should be 93 with that version.

Thanks!
