-		In the next stage, the encoder tries to approximate the signal with a function in such a way that when the approximation is subracted, the result (called the <i>residual</i>, <i>residue</i>, or <i>error</i>) requires fewer bits-per-sample to encode.  The function's parameters also have to be transmitted so they should not be so complex as to eat up the savings.  FLAC has two methods of forming approximations: 1) fitting a simple polynomial to the signal; and 2) general linear predictive coding (LPC).  I will not go into the details here, only some generalities that involve the encoding options.<br />

 		First, fixed polynomial prediction (specified with <span class="argument">-l 0</span>) is much faster, but less accurate than LPC.  The higher the maximum LPC order, the slower, but more accurate, the model will be.  However, there are diminishing returns with increasing orders.  Also, at some point (usually around order 9) the part of the encoder that guesses what is the best order to use will start to get it wrong and the compression will actually decrease slightly; at that point you will have to you will have to use the exhaustive search option <span class="argument">-e</span> to overcome this, which is significantly slower.<br />

 		FLAC currently defines two similar methods for the coding of the error signal from the prediction stage.  The error signal is coded using Rice codes in one of two ways: 1) the encoder estimates a single Rice parameter based on the variance of the residual and Rice codes the entire residual using this parameter; 2) the residual is partitioned into several equal-length regions of contiguous samples, and each region is coded with its own Rice parameter based on the region's mean.  (Note that the first method is a special case of the second method with one partition, except the Rice parameter is based on the residual variance instead of the mean.)<br />

-		The FLAC format has reserved space for other coding methods.  Some possiblities for volunteers would be to explore better context-modeling of the Rice parameter, or Huffman coding.
