commit 2007-07-31, author: Josh Coalson, committer: Josh Coalson

"document blocksize strategy bit, RESIDUAL_CODING_METHOD_PARTITIONED_RICE2, new subset sample rates, subset clarification, variable blocksize clarification"



Before:
"The blocksize bits in the frame header must be 0001-0101 or 1000-1110, specifying a fixed-blocksize stream (the exception being the last block as described in the table) and a few allowable blocksizes. This also means that the STREAMINFO metadata block must specify equal mininum and maximum blocksizes. If the sample rate is <= 48000Hz, the blocksize must be <=4608, i.e. blocksize bits 0001-0101 or 1000-1100."



After:
"The blocksize bits in the frame header must be 0001-1110. The blocksize must be <=16384; if the sample rate is <= 48000Hz, the blocksize must be <=4608."
