"EXP-GOLOMB2 PARTITION ENCODING PARAMETER" (see | | | section on EXP-GOLOMB2 PARTITION ENCODING PARAMETER | | | (#expgolomb2-partition-encoding-parameter)) | +----------+-----------------------------------------------------+ | u(?) | "ENCODED RESIDUAL" (see section on ENCODED RESIDUAL | | | (#encoded-residual)) | +----------+-----------------------------------------------------+ Table 41 Sandelman & Weaver Expires 29 October 2021 [Page 33] Internet-Draft FLAC April 2021 11.27.3.2. EXP-GOLOMB2 PARTITION ENCODING PARAMETER +===========+==========================================+ | Value | Description | +===========+==========================================+ | 0b00000 - | Exp-golomb parameter. | | 0b11110 | | +-----------+------------------------------------------+ | 0b11111 | Escape code, meaning the partition is in | | | unencoded binary form using n bits per | | | sample; n follows as a 5-bit number. | +-----------+------------------------------------------+ Table 42 11.27.4. ENCODED RESIDUAL The number of samples (n) in the partition is determined as follows: * if the partition order is zero, n = frame's blocksize - predictor order * else if this is not the first partition of the subframe, n = (frame's blocksize / (2^partition order)) * else n = (frame's blocksize / (2^partition order)) - predictor order 12.
