How can I play a wav-file from memory or blob-field?Sometimes you needs to play a some sounds from own app but store these sounds in blob-field of table or in some external files. To play a wav-file you must call the playsound procedure which have the few parameters-sound (which you want to play ), handle of file with resource (only for WAV from EXE/DLL-file) a

PHP implements the method of converting a WAV file into an image file and displaying it in a page. The examples in this paper are the methods that PHP implements to convert WAV files into image files and display them in a page. Share to everyone for your reference. The specific analysis is as follows: Requirements: Convert WAV files to PNG files and display them

WAV files are resource Interchange file formats (RIFF), including a number of named blocks that contain header information, such as a sound sampling format, or data (such as the sample itself). The Win API provides functions such as turning off Fiff files, finding blocks, and so on. The names of these functions begin with "Mmio". The DirectSound API does not include methods for writing WAV files. However,

This uses FAAC to implement AAC encoding. In addition, the data segment of WAV is PCM, the code will appear many PCM abbreviations. 1 Download and install FAAC The installation process here is implemented on MAC and Linux, and windows can be similar to the reference. wget http://downloads.sourceforge.net/faac/faac-1.28.tar.gz tar zxvf faac-1.28.tar.gz cd faac-1.28 . Configure make sudo make install If prefix path is used in the default configure, t

, 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

Windows mCi (media control interface) Yes Windows Provides high-level and general control over multimedia devices. . It provides a set of device-independent functions and Command to effectively control multimedia devices. By using MCI, we can easily perform operations on multimedia without having to understand the working principle of multimedia devices and call the underlying function library, which greatly reduces the difficulty and burden of development. Here is a small example of a

Sometimes, we write the program need to play music, generally we will use the following ways: 1. Place music files in a specific directory, such as Sound,wav,music for the program to read and play; 2. Use resources to store music. Some people may also use this method, but most people might have to release the music files from the resources before they read the playback. The way I'm going to present today is to load the music files directly into memory

First, your resources should be in WAV format and include header files and required library files as follows#include #pragma comment (lib, "Winmm.lib") The declaration of the PlaySound function is: BOOL PlaySound (lpcstr pszsound, hmodule hmod,dword fdwsound); PlaySound (null,null,null); stop playing. 　 The parameter pszsound is a string that specifies the sound to play (generally the absolute path, if the sound file is copied to the executable file

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
