Filtering multi-dimensional data

[BenjaminNavarro]

I couldn't find a way by looking at the docs on how to filter multi-dimensional data. I have the impression that you have to create one filter per dimension, which can be very inconvenient.

I am missing something? If not, what would be the simplest way of adding the feature?

KFR is mainly intended for audio filtering where each channel is processed separately from other. So yes, currently this is the only available way to do multi-channel filtering.
