铃声增强补丁的疑问

kingsonic

dcl.ini、iir.ini这2个文件具体起什么样的控制？

iir.ini

;;; General Configuration ;;;
[GeneralConfig]
EnableIIR= 0     ; 0 = disabled, other = enabled

打补丁前，EnableIIR=1，这个什么意思？应该是全局控制的。

;;; Builtin Speaker, Sample Rate 8000 Hz ;;;
[BuiltIn8000]
gain= 18646 （这个是灵敏度或者声音电平的意思）
no_biquads= 1
coeffs0= -16384 16384 7723 -5461

这样的语句具体是怎么控制的？


dcl.ini

;;; Sample Rate 8000 Hz ;;;
[8000]
LimL=  -10       ; Power limitation: 10 x dB
LimC= -400       ; Compression range: 10 x dB
LimE= -650       ; Expansion range: 10 x dB
GainC= 250       ; Compression gain: 10 x dB
UpdateExpUp= -1  ; Release (slow gain up)
UpdateExpUd= -1  ; Release (fast gain up)
UpdateExpDn= -1  ; Attack (fast gain down)
BlockExp= -1     ; Defines block size for processing (2^-BlockExp)
MeanExp= -5      ; Parameter for initial initialisation

这里的L、C、E是代表频段吗？频率是怎么分段的？

谁能说说？谢谢
我想修改这2个声音控制文件看看，老感觉铃声增大补丁的效果太粗燥了，因为原始8000HZ比其它采样大50

这2个和我们修改后的不一样

没有人知道？

具体参数不是很了解～
