/******
效果配置说明:
1.EFFECT_PITCH_SHIFT 移频,变调不变速,init_parm.shiftv调节有效,init_parm.formant_shift调节无效
2.EFFECT_VOICECHANGE_KIN0 变声,可以调节不同的 init_parm.shiftv 跟 init_parm.formant_shift ,调出更多的声音效果
3.EFFECT_VOICECHANGE_KIN1 变声,同EFFECT_VOICECHANGE_KIN0类似的,但是2者由于运算的不同,会有区别。
4.EFFECT_ROBORT 机器音效果,类似 喜马拉雅那样的
5.EFFECT_AUTOTUNE 电音效果
