psymodel_init

public final int psymodel_init(LameGlobalFlags gfp)

NOTE: the bitrate reduction from the inter-channel masking effect is low compared to the chance of getting annyoing artefacts. L3psycho_anal_vbr does not use this feature. (Robert 071216)

public final float ATHformula(float f,
                              LameGlobalFlags gfp)
