wav to wav

WAV is a sound file format developed by Microsoft (Microsoft) that conforms to the riff (Resource Interchange File format) documentation specification for storing audio information resources for the Windows platform. Widely supported by Windows platforms and applications, this format also supports a variety of compression algorithms such as Msadpcm,ccitt A, which supports multiple audio numbers, sampling frequencies and channels, standard formatted

Ask for help: My job requirement is to generate a waveform diagram of a MP3 file. My idea is to first generate a WAV file MP3, and then use the WAV file to generate a waveform diagram. All the process will not, ask for help. Originally, I want to exec (lame ...) This converts the MP3 into WAV, but finds that sometimes the conversion fails. Later, some experts

This design idea: first open a normal WAV audio file, from the 44 bytes in front of the defined file header, remove the file header definition message, placed in a file header structure. Then open the ALSA audio driver, from the file header structure to remove the sampling accuracy, the number of channels, sampling frequency three important parameters, using the ALSA audio-driven API set parameters, finally open the

, 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
