I am implementing this, though I will refrain from adding it to the documentation for now, as it is a feature that should be used with care (i.e. only if the user actively applies a low-pass filter beforehand).

Hi Eelke, I think this option was already implicitly present, when selecting the correct interpolation method.

(In reply to Jan-Mathijs Schoffelen from comment #3) Hi JM, the interpolation method only applied to resampling based on novel time axes. Now I implemented downsampling (using cfg.resamplemethod = 'downsample', where 'resample' is the default) based on cfg.resamplefs (which needs to be a proper divisor of the original Fs, of course).
