And some people have claimed that they got some better performance doing that , so you certainly could do that easily. But the fundamental difference , I mean , there 's other small differences
There 's a cubic root that happens , right ?
Yeah , but , you know , as opposed to the log in the other case. I mean  the fundamental d d difference that we 've seen any kind of difference from before , which is actually an advantage for the P L P i uh , I think , is that the  the smoothing at the end is auto - regressive instead of being cepstral  uh ,  from cepstral truncation. So um it 's a little more noise robust.
Hmm.
