First of all, this is the first time I have compiled such a large project, so I have taken some detours. Because I want to learn about speech processing, I will compile the source code of audacity under sf. I use audacity1.3.9 version. first, find the compile.txt file in win.com. This is the instruction file compiled in windows. The instructions above are clear (only in English) and the compilation tool is vs2008.

1, we have prepared the material to understand, now open the Audacity software and then import a section of audio footage as shown below
2, then we find the noise of the band
3, then we in the interface to click the effect of the denoising, the results are as follows
4. After the selection, we will adjust the value according to the size of the noise, then click to get the characteristic of noise.
5, then we CTRL + a
In linux, the audio editing software audacity-the technology of the Linux release-Debian information. For more information, see the following section. Audacity is a relatively early audio processing gui in linux. It can export wav, mp3, ogg, and other formats. In terms of operation, it is silly to say it in a graphical way.

Compiler built-in macros:
First, we will introduce several built-in macro definitions of the compiler. These macro definitions can not only help us write cross-platform source code, but also help us output useful debugging information flexibly.
The ansi c standard has several predefined macros (which are also commonly used ):
_ Line __: Insert the current source code line number into the source code;
_ File
The concept of macro macros is found in many languages.In general, the mechanism of a macro is to replace or expanded a macro that has already been defined at the pre-compilation stage, that is, to replace the macro by its name with the contents of the macro.The macros in Rust are different!The macros in rust are also
To write a good C language, a beautiful macro definition is very important. Macro definitions can help us prevent errors, improve code portability and readability, and more.In the software development process, there are often common or common functions or code snippets that can be written as functions or encapsulated as macro definitions. So is the function good
