How to split frame to high and low band

[CobraCalle]

Hello,

I`m currently writing a .net wrapper for your lib, because I would like to use it in a dotnet based application on Linux.

At the moment I got stuck at WebRtcNs_Process... can anyone give me a hint how to split the wave-frame from the mic into H- and L-band (and of course merge the filtered results).

Thank you very much for your help
