aacdec_usac: always zero out alpha_q values for stereo streams The issue is that if a frame has no complex stereo prediction, the alpha values must all be assumed to be zero if the next frame has complex prediction and uses delta coding. [DH] libavcodec/aac/aacdec_usac.c

aacdec_usac: rename spectrum decode function and remove unused arg The LC part of the decoder combines scalefactor application with spectrum decoding, and this was the plan here, but that's not possible, so change the function name. [DH] libavcodec/aac/aacdec_usac.c

aacdec_usac: dequantize scalefactors after noise synthesis The issue here is that the spec implied that the offset is done on the dequantized scalefactor, but in fact, it is done on the scalefactor offset. Delay dequantizing the scalefactors until after noise synthesis is performed, and change to apply the offset onto the offset. [DH] libavcodec/aac/aacdec_usac.c
