Q The choice of big endian or little endian depends on the computer platform that was used to generate I/Q data. Zero-bit data is basically a sample with 0 amplitude. This structure is used by SDL_OpenAudio and SDL_LoadWAV. name: A name for the operation (optional). You only have to worry about swapping the bytes yourself when reading raw binary soundfiles from a foreign computer, or when digging the sound samples out of an ``unsupported'' soundfile format yourself. That way, you could fill in all the fields (in an endian correct manner) and then do one single fwrite(). The format is in Microsoft's Little-Endian byte order. Passing in null for the allocation callbacks object will cause dr_wav to use defaults which is the same as DRWAV_MALLOC,. For example: if you write out a graphics file (such as a.
