In the LPC analysis of time domain signals, the order of the LPC all pole filters will
determine the number of frequency components that it could estimate.. For example, a 10th order LPC filter can at most estimate 5 frequency components..
There are 10 poles (freq components) from 0 to the sampling freq.. Half is taken
as we are only interested up to the Nyquist freq..

On the other hand, LPC analysis in freq domain will attempt to model the number of transients in time domain.. How is the order of the LPC filter related to the number of time domain transients ??

Since the MDCT maps sines to pulses and the other way round you could argue: An order 10 LPC filter in the freq domain is capable of "estimating" 5 time domain pulses.
