What is a WAV file.The WAV file directly reflects the size of a sound at each time point, for example, the following waveform:Take one point for 0.1 seconds each person. The obtained WAV file value is 0, 1,-, 1. Therefore, if we can directly add the data of many wav files, you will hear all the sounds, which is the principle of the mixer.The following is an analysis of the wav

Introduction to the elf file format2014-11-02 The elf represents executable and linkable forma, a file format used for executable files, destination files, and libraries, similar to the PE file format under Windows. The ELF format

We encountered a time-consuming task in our work. To read txt documents without garbled characters, We need to encode and convert the txt documents. Open the txt file and save it as the required encoding format. If the txt file is small, the conversion is not too slow, but if the file is too large, the program will be

Before watching some videos, video files will be available in many formats, because formatting problems often require conversion of these formats. In the same way, there are many types of document formats available today, and sometimes it is necessary to convert a PDF document into a different document format for easy application.Many document formats can be saved to the PDF file

The ply file format is a set of 3D mesh model data formats developed by Stanford University. many well-known model data in the graphic field, for example, Stanford's 3D scanning database [1] (including the happy Buddha, dragon, and bunny rabbits that are seen in many articles), geogia tech's large Geometric Model Library [3], north Carolina (UNC) power plant model [4] and so on, the initial model is based o

From: http://blog.csdn.net/longxin007/article/details/1880477 PrefaceIf common programming doesn't need to know these things, if you want to precisely control the format of your object file or you want to view the content in the object to make some judgment, just now you can look at the following tools in idea: objdump, nm, ar. Of course, this article cannot explain in detail their usage and functions. If y

Detailed description of MapInfo File Format In Mapinfo, each map is called a layer (or table ).Each MapInfo table consists of two most important parts: Graphs (called spatial objects) and data (called attributes ).MapInfoOne-to-one connection between "graphic objects" and "attribute data" is implemented to query graphic data and attribute data in two directions. MapInfo supports attribute-based Quick query

We know that not all binaries in the Linux environment have the same format, and the Linux system uses binary file handlers to implement separate processing for different binary format files. The binary handler identifies the file through a "feature sequence" (a special sequence of bytes) embedded at the beginning of t
