心理声学模型table读取之介绍
来源：互联网 发布：网络通信的发展状况 编辑：程序博客网 时间：2024/05/16 05:19
一、l3psy.c简单介绍
只要做过心理声学模型的，对l3psy.c这个文件应该不陌生, 该文件由
void L3_psycho_initialise( void )
void L3_psycho_analize( int channel,
short *buffer,
short savebuf[1344],
float snr32[32],
double ratio_d[21],
double ratio_ds[12][3],
double *pe,
gr_info *cod_info )
void L3para_read( void )
三个函数组成。
L3_psycho_initialise 负责初始化心里声学模型中的一些常数据.
L3_psycho_analize 负责心理声学模型过程, 如感官熵计算,窗切换,门限计算这些硬骨头
L3para_read 负责读取 11172_3_ANNEXC 中的 Table 3.-C.7, Table 3-C.8
二、Table 3.-C.7, Table 3-C.8介绍
Table 3.-C.7, Table 3-C.8 在规范 11172_3_ANNEXC 中定义
Table 3.-C.7 在规范中的定义为 ：
Table 3-C.7: Threshold calculation partitions with following parameters:
width, minval, threshold in quiet, norm and bval:
Table 3-C.7由以下几个参数构成 :
no. FFT-lines minval qthr norm bval
其中各个参数的意义为 :
NO ---- 分区号, 或者说是第几个分区(我理解频率被分为N个partition)
FFT-lines ---- 该分区内的频线个数, 就是该分区内容纳了多少个不同的频率
minval ---- minval[b]为SNR最小值可查表得到
qhtr ---- 遮蔽门限
norm ---- 归一化系数.
Bval ---- the median bark value of the partition
Table 3-C.7由以下6个表组成(有三个频率48， 44.1， 32)
Table 3-C
long blocks
48KHz long block 上 N 个partition 的详细信息
Table 3.-C.7b: Sampling_frequency = 44.1 kHz
long blocks
44.1KHz long block 上 N 个partition 的详细信息
我的是44.1KHz, 这个N是63， 也就是说44.1Khz下，long block类型是分成了63个分区, 各个分区的频线个数, 遮蔽门限, 归一化系数都在这个表中列出来了.
Table 3-C
long blocks
32KHz long block 上 N 个partition 的详细信息
Table 3-C.7d: Sampling_frequency = 48 kHz
short blocks
48KHz short block 上 N 个partition 的详细信息
Table 3-C.7e: Sampling_frequency = 44.1 kHz
short blocks
44.1KHz short block 上 N 个partition 的详细信息
Table 3-C
short blocks
32KHz short block 上 N 个partition 的详细信息
Table 3.-C.8 在规范中的定义为 ：
Table 3-C.8: Tables for converting threshold calculation partitions to scalefactor bands
Table 3-C.8由以下几个参数构成 :
no. sb cbw bu bo w1 w2
其中各个参数的意义为 :
no 分区号, 或者说是第几个分区(我理解频率被分为N个partition)
cbw 不知道如何表述cbw， 规范里描述cbw的语句
The table contains also the number of partitions (cbw) converted to one scalefactor band (excluding the first and the last partition)
我理解为cbw个遮蔽频带转成一个缩放因子频带, 但是第一个和最后一个遮蔽频带不算在内. 事实的确如此, 我们以为Table 3-C.8b为例子
查看这个表
no.sb cbw bu bo w1 w2
0 3 0 4 1.000 0.056
1 3 4 7 0.944 0.611
.
.
.
19 2 57 59 0.357 0.722
20 2 59 61 0.278 0.960
省却掉中间部分,
注意看no=1时,bo~bu=[0,3)共4个遮蔽频带， 但cbw却是3;
注意看no=20,bo~bu=[59,61]共3个遮蔽频带, 但cbw却是2
在注意看no=其他值, 比如说no=1, bo~bu是[4,7)确实是cbw=3。
bo The parameters bo and bu are shown in the table 3-Annex 3-C.8 used for converting threshold calculation partitions to scalefactor bands.
Bu The parameters bo and bu are shown in the table 3-Annex 3-C.8 used for converting threshold calculation partitions to scalefactor bands.
w1 The first partition which is added to the scalefactor band is weighted with w1, the last with w2
w2 The first partition which is added to the scalefactor band is weighted with w1, the last with w2
这里有个概念, 我不知道自己理解的是不是对, 在规范中是如此描述
“The table contains also the number of partitions (cbw) converted to one scalefactor band (excluding the first and the last partition)”
我理解为Table 3-C.8讲述的是讲信号从遮蔽频带转换到缩放因子频带使用的规范.
Table 3-C.8由以下6个表组成(有三个频率48， 44.1， 32)
Table 3-C
long blocks
Table 3-C.8b: Sampling_frequency = 44.1 kHz
long blocks
我的是44.1KHz的， 我的理解是该表描述的是从遮蔽频带转换到缩放因子频带的规范.
Table 3-C.8c: Sampling_frequency = 32 kHz
long blocks
Table 3-C.8d: Sampling_frequency = 48 kHz
short blocks
Table 3-C.8e: Sampling_frequency = 44.1 kHz
short blocks
Table 3-C.8f: Sampling_frequency = 32 kHz
short blocks
三、表组织
由第二部分的讲解就不难理解psy_data.h中的表定义了. 而且该文件内的频率还多3个.
//#warning HURL, this should be different, lazyness....
/*
SNR
{ Indicates the strength of the transcoded signal compared to
the original signal, in decibels (dB).
First the mask-to-noise ratio "MNR" for each subband is calculated by
subtracting from the signal-to-noise-ratio "SNR" the signal-to-mask-ratio "SMR":
MNR = SNR - SMR
The signal-to-noise-ratio can be found in the 3-Annex C, Table 3-C.2.,
"LAYER I SIGNAL-TO-NOISE-RATIOS". The signal-to-mask-ratio is the output of
the psychoacoustic model.
======================================================================
SMR
singal-to-mask ratio
SNR
singal-to-noise ratio
MNR
mask-to-noise ratio
MNR(m) = SNR - SMR(m) (in dB)

/*
* 6个为一个段, 这6个频率分别是 48000, 44100, 32000 24000, 22050, 16000.

char* psy_data[] = {
/********************************************************************************
第一段, 列出48000, 44100, 32000 24000, 22050, 16000采样频率下 partition 结构划分.
long block
以44.1KHz为例, 讲解该表结构
44.1KHz下, 分割成63个区间
"freq = 44100.0 partition = 62 ",
"No= 0 #lines= 1 minval=24.5 qthr= 4.532 norm=0.951 bval=0.000",//描述的是一个partition内的全部信息
"No= 1 #lines= 1 minval=24.5 qthr= 4.532 norm=0.700 bval=0.431",//描述的是一个partition内的全部信息
"No= 2 #lines= 1 minval=24.5 qthr= 4.532 norm=0.681 bval=0.861",//描述的是一个partition内的全部信息
NO 分区号, 或者说是第几个分区
lines 该分区内的频线个数, 就是该分区内容纳了多少个不同的频率
minval minval[b]为SNR最小值可查表得到
qhtr 遮蔽门限
norm 归一化系数.(物理意义是???????)
bval the median bark value of the partition

四、读psy_data.h中的表

/**
* 该函数实现两个功能 :
* 1. 读 11172_3_ANNEXC 中的 Table 3.-C.7, Table 3-C.8
* 对于44.1KHz来说, 就是 :
* Table 3.-C.7b, Table 3.-C.7e, Table 3-C.8b, Table 3-C.8e
*
* 2. 计算spreading function.
*
*
* 该函数分为四个模块 ：
* 第一段和第二段是读Table 3.-C.7并做spreading function计算.
* 第三第四段是读Table 3.-C.8为"门限频带转换为缩放因子频带",
* 准备数据.
*
*
* 其中 :
* Table 3.-C.7b
* 描述的是44.1KHz, 门限分为63(CBANDS)个partitions (long block)
*
* Table 3.-C.7e
* 描述的是44.1KHz, 门限分为42(CBANDS_s)个partitions (short block)
*
* Table 3-C.8b
* 描述的是44.1KHz, threshold calculation partitions to
* scalefactor bands (long block)
* 63个门限频带转换为21(SBMAX_l)缩放因子频带,
*
* Table 3-C.8e
* 描述的是44.1KHz, threshold calculation partitions to
* scalefactor bands (short block)
* 42个门限频带转换为12(SBMAX_s)缩放因子频带.
*
*
* 后记 :
* 如果想详细了解该函数的来龙去脉, 需要查看 psy_data.h 和 11172_3_ANNEXC.doc
