function [S, sfc, G] = AACquantizer(frameF, frameType, SMR) %Implementation of Quantizer % Usage [S, sfc, G] = AACquantizer(frameF, frameType, SMR), where: % Inputs % - frameF is the frame in the frequency domain, in MDCT coefficients % representation containing only one of the audio channels stored in % a vector of length 1024 % - frameType is the type of the current frame in string % representation, can be one of "OLS" (ONLY_LONG_SEQUENCE), "LSS" % (LONG_START_SEQUENCE), "ESH" (EIGHT_SHORT_SEQUENCE), "LPS" % (LONG_STOP_SEQUENCE) % - SMR is the signal to mask ratio array of dimensions 42X8 for % EIGHT_SHORT_SEQUENCE frames and 69X1 otherwise % % Output % - S are the MDCT quantization symbols of one audio channel stored % in a vector of length 1024 % - sfc are the scalefactors per band stored in an array of % dimensions NBX8 for EIGHT_SHORT_SEQUENCE frames and NBX1 % otherwise, where NB is the number of bands % - G is the global gain stored in an array of dimensions 1X8 for % EIGHT_SHORT_SEQUENCE frames and a single value otherwise end
