Method Detail

setModules

public final void setModules(QuantizePVT qupvt)

noquant_count_bits

public int noquant_count_bits(LameInternalFlags gfc,
                              GrInfo gi,
                              CalcNoiseData prev_noise)

count_bit

count_bits

public int count_bits(LameInternalFlags gfc,
                      float[] xr,
                      GrInfo gi,
                      CalcNoiseData prev_noise)

best_huffman_divide

public void best_huffman_divide(LameInternalFlags gfc,
                                GrInfo gi)

best_scalefac_store

public void best_scalefac_store(LameInternalFlags gfc,
                                int gr,
                                int ch,
                                IIISideInfo l3_side)

Find the optimal way to store the scalefactors. Only call this routine after final scalefactors have been chosen and the channel/granule will not be re-encoded.

scale_bitcount

public boolean scale_bitcount(GrInfo cod_info)

Also calculates the number of bits necessary to code the scalefactors.

scale_bitcount_lsf

public boolean scale_bitcount_lsf(LameInternalFlags gfc,
                                  GrInfo cod_info)

Also counts the number of bits to encode the scalefacs but for MPEG 2 Lower sampling frequencies (24, 22.05 and 16 kHz.) This is reverse-engineered from section 2.4.3.2 of the MPEG2 IS, "Audio Decoding Layer III"

huffman_init

public void huffman_init(LameInternalFlags gfc)
