编写opensmile配置文件

编写opensmile配置文件

openSMILE可以生成简单场景的配置文件模板。

1.创建一个myconfig,用来保存配置文件

如：在opensmile-2.3.0\config目录下创建myconfig文件夹

2.输入一下内容，生成配置文件

D:\Software\OpenSMILE\msvcbuild>SMILExtract_Release
-cfgFileTemplate -configDflt cWaveSource,cFramer,cEnergy,cCsvSink 
-l 1 2>D:\Software\OpenSMILE\opensmile-2.3.0\config\myconfig\myconfig1.conf

-cfgFileTemplate：opensmile生成一个配置文件的模板

-configDflt：用于指定一个逗号分隔的组件列表

-l 1：1选项将日志级别设置为1，以禁止配置文件中不应该出现的任何消息。

       (但是仍然会在日志级别1上收到错误消息，例如通知您所指定的组件不存在的消息等)

2>：将其转储到文件mmyconfig1.conf中

如果要在生成的配置文件中添加描述各个选项行的注释，请将选项-cfgFileDescriptions添加到上述命令行。

生成的myconfig1.conf的内容

配置文件myconfig1.conf由两个逻辑部分组成。

文件中的 注释以;或者//开头

第一部分包含的是配置文件的组件，例如：waveSource、framer、energy等等。

它包含组件管理器的配置，该配置确定在调用SMILExtract时实例化哪些组件。总是必须有一个cDataMemory组件，然后是其他组件。在[ ]中给出的名称指定组件实例的名称，该名称在一个配置中必须是唯一的。

第二部分就是对各组件的配置

[实例名:组件类型]

[waveSource:cWaveSource]

[framer:cFramer]

[energy:cEnergy]

[csvSink:cCsvSink]

配置组件连接

这可以通过分配dataReader和dataWriter组件并设置名为数据存储器“levels”实现

通过修改reader.dmLevel和writer.dmLevel。

可以为writer level选择任意名称。因为dataWriters会在数据存储区注册并创建您为writer.dmLevel的level。然后通过reader.dmLevel的读取level来连接组件。

规则：

1.对于一个level，只有一个writer可以存在，即只有一个组件可以写入一个level。

2.一个组件可以从多个level读取，如果您指定多个level名称用“;”隔开，比如reader.dmLevel = energy;loudness

从energy和loudness level中读取数据。数据将以列的形式串联。

示例：

对于我们的示例配置，我们希望cFramer组件从输入PCM中读取由cWaveSource组件提供的流，每10毫秒创建一个25毫秒的帧，把这些帧写入到一个新的level，我们称之为“energy”），因此我们需按照下面改变内容：

将

   

改为

将

改为：（注意，我们删除了一些多余的frameSize *选项，并将frameStep更改为0.010）

[framer:cFramer]
reader.dmLevel = wave
writer.dmLevel = waveframes
copyInputName = 1
frameMode = fixed
frameSize = 0.025000
frameStep = 0.010000
frameCenterSpecial = left
noPostEOIprocessing = 1

接下来，cEnergy组件将读取音频帧并计算信号对数能量，cCsvSink会把他们写进一个CSV格式的文件。因此我们把相应的行改为：

将

[energy:cEnergy]
reader.dmLevel = <>
writer.dmLevel = <>
nameAppend = energy
copyInputName = 1
EOIlevel = 0
processArrayFields = 0
includeSingleElementFields = 0
preserveFieldNames = 1
htkcompatible = 0
rms = 1
energy2 = 0
log = 1
escaleLog = 1
escaleRms = 1
escaleSquare = 1
ebiasLog = 0
ebiasRms = 0
ebiasSquare = 0

改为：

将

[csvSink:cCsvSink]
reader.dmLevel = <>
errorOnNoOutput = 0
filename = smileoutput.csv
delimChar = ;
append = 0
timestamp = 1
frameTime = 1
number = 1
frameIndex = 1
printHeader = 1
flush = 0
// instanceBase = 
// instanceName = 

改为：

但是目前在这个confg文件中，输入输出的文件名是固定的，输入文件名input.wav，输出文件名myenergy.csv为如下图所示

      

如果想在cmd命令行中指定输入，输出文件名，则修改配置为：

输入文件名：filename = \cm[inputfile(I):file name of the input wave file]

输出文件名：filename = \cm[outputfile(O):file name of the output CSV file]

使用myconfig.conf测试一下：

D:\Software\OpenSMILE\msvcbuild>SMILExtract_Release
-C "D:\Software\OpenSMILE\opensmile-2.3.0\config\myconfig\myconfig1.conf" 
-I "D:\Software\OpenSMILE\input\opensmile.wav" 
-O "D:\Software\OpenSMILE\output\opensmile.csv"
