, Java programmers define some native methods on the Java side and provide these methods to C programmers in the form of a C-language header file.|-Then, c programmers use the C language to implement functions defined in the header files provided by the Java programmer.|-Next, the C programmer packages the function into a library file and gives the library file to the Java programmer.When the Java program executes, if the native method is called in a class, the virtual opportunity passes through

WAV is a lossless sound file under Windows, the file holds the audio PCM information and the player plays that music when most information is made, he has two blocks, the first block is the format block, the second block is the data blockFirst, the format block, the format block with a picture can be explained, as followsUsing Winhex to analyze a WAV audio file, Han Lei's farewell message is as followsBy co

value is the number of channels × the data bit value per sample/8. The playback software needs to process multiple bytes of data of this value at a time to adjust the value for the buffer zone. 22 h 2 　 The number of data digits of each sample, indicating the number of data digits of each sample in each channel. If multiple channels exist, the sample size is the same for each channel. 24 h 4 Char DATA tag "data" 28 h

Another product of the company, when monitoring CTI, the recording format is PCM.To play in IE, You need to convert it into a standard WAV. previously, I used a com library for conversion. Now I can't use that library for various reasons (64-bit support is not good), So I implemented it in Java. The basic code is as follows.In fact, WAV is only a PCM file with the relevant file header and description inform

Problem You want to have a method for playing sound quickly. Solution In xna3.0, you can directly load and play sounds from xNa without loading them using xact. Although this method removes some advanced xact functions, it makes playing sound very easy. Working Principle First, add a sound file to the project. The method is the same as adding an image to the project. For more information, see tutorial 3-1. The simplest solution is to drag a .wav fi

To convert audio files in WAV format to MP3 format, there is no need to find a special format conversion tool. It is not that complicated. Your computer has a ready-made tool, this is the "recorder" in the Windows attachment. Using this tool, you can easily convert the WAV format to the MP3 format. The procedure is as follows:Choose Start> program> attachment> Entertainment> recorder, open the recorder prog
