Warning: Odd order symmetric FIR filters must have a gain of zero at the Nyquist frequency. The order is being increased by one. > In fir1 at 85 In ft_preproc_highpassfilter at 81 In trunk/private/preproc at 314 In ft_preprocessing at 300 Is there a way to precompute the appropriate filter order beforehands? It is a bit annoying, because it suggests that I did something wrong

I introduced this new selection of default filter order, so will take a look.
