Storing audio file into an array/stringstream C++

I would like to send the contents of an audio file to another system over the network using socket. Both systems run on Windows operating system. Is there a tutorial on some way to store the audio contents into a C++ array or Stringstream datatype, so that it will be easier to send it to a different node.

I basically want to know how to extract data bytes from an audio file.

The easiest thing to do is to simply send the data in chunks of bytes. If you are starting with an audio file, just open it like any other binary file with something like file = fopen(filename, "rb"); (where filename is the name of the audio file). Then enter a loop to read a chunks of bytes until you reach the end of the file. Just use something like bytes_read = fread(buffer, sizeof(char), read_size, file); where buffer should probably be a char array of at least size read_size, which could be, say, 1024. After each fread, you can make your network send call. Alternately, you could read the whole file first and then send it chunk by chunk. Your call. Either way, when you reach the end of the file, send some sort of signal that you have reached the end. The receiving system should take these chunks and call fwrite to create a new audio file. You can either append each chunk as it comes in or buffer it all until you reach the end and then write it all out.

soundfile++ can be used if you have wav files only. Check the readtest and writetest demo programs here http://sig.sapp.org/doc/examples/soundfile/
