Do Rice parameter optimization. By default the encoder uses a single Rice parameter for the subframe's entire residual. With this option, the residual is partitioned into 2^n pieces, each with its own Rice parameter. Higher values of n yield diminishing returns. The most bang for the buck is usually with <B><TT>-r 2</TT></B> (more for higher blocksizes). This usually shaves off another 1.5%. The technique tends to peak out about when blocksize/(2^n)=128. Use <B><TT>-r 99</TT></B> to force the highest degree of optimization.
