I have no idea , because the issue I brought up was with a very simple spectral subtraction approach ,
Mmm.
and the one that  they use at OGI is one from  from  the proposed  the  the  the Aurora prop uh , proposals , which might be much better. So , yeah. I asked  Sunil for more information about that , but , uh , I don't know yet. Um. And what 's happened here is that we  so we have this kind of new , um , reference system which  use a nice  a  a clean downsampling - upsampling , which use a new filter  that 's much shorter and which also cuts the frequency below sixty - four hertz ,
