This allows them to use a single 16x16->32 multiply instead of a 24x8->32 multiply. Also change the time-frequency resolution flag coding to ensure that "0" is always the most-probable symbol (i.e., that prob("1")<50%), as that's where all the rounding error accumulates.Provide direct implementations ec_{enc|dec}_bit_prob() that do not require a division instead of using the normal entropy coder path. This should be exactly equivalent to the existing code.Cleaning up VBR to be frame-size independentFolding tuningRD optimisation now takes bitrate into accountSimplification to the transient detection codeMore simplifications to the Viterbi codeSimplifications to the tf_res RD codeViterbi-based RD optimization of the tf_res decisionschanging probability of first tf resolution symbolAdaptive time-frequency resolutionAdds a range coder call to encode a single bit with arbitrary probabilityFixed a long-standing rare mismatchRe-organised the special case for N==1Bunch of fixes for frames of 2.5 ms.More recombining "infrastructure"Code for recombining bands (not enabled yet)Removing the rest of the >32-bit PVQ codeMinor code simplificationsDoing folding from the highest freq possibleIncreasing the temporal resolution of transientsImproving the transient detectionSplitting transients in time domainMoving code to quant_band()
