  1. abs(a)<abs(b)? swap bsSymbit1=1 bsSymbit1=0 a-b<0 || (a==b && a<0 && b<0 )? negative bsSymbit0=1 bsSymbit0=0 a+b even? s=(a+b)/2 d=(a-b)/2 s=(2*lav+1-(a+b))/2 d=s+b

  2. parameter sets parameter bands 71 hybrid subbands 0 1

  3. Coding a frame: Decide XXXDataMode Decide FreqStride & pairflag Entropy coding 2 subsequent sets are both LOSSLESS? Mode== LOSSLESS? Y N Find a common stride for both sets ,making err<threshold1 Find the best stride of the set, making err<threshold2 dataSets ++ Found? Y N Pairing the 2 sets and striding Find individual strides, making err<threshold3 Found? Y N No pairing but striding Pairing with stride=1
