Only LDA. Yeah. Af - I  after that I added on - line normalization , yeah.
Mm - hmm. So we just tried directly to  to just , keep the system as it was and , um , when we plug the spectral subtraction it improves uh , signif significantly. Um , but , what seems clear also is that we have to retune the time constants of the on - line normalization.
Yeah , yeah. Yeah.
Because if we keep the value that was submitted uh , it doesn't help at all. You can remove on - line normalization , or put it , it doesn't change anything. Uh , uh , as long as you have the spectral subtraction. But , you can still find some kind of optimum somewhere , and we don't know where exactly
