In addition to the standard and nonstandard waveform formats previously presented in this chapter, there are two Clipboard formats that can be used to represent audio data: CF_WAVE and CF_RIFF. Use the CF_WAVE format to represent data in one of the standard formats, such as 11 kHz or 22 kHz PCM. Use the CF_RIFF format to represent more complex data formats that cannot be represented as standard wave files.
