Querying Waveform-Audio Input Devices

Before recording waveform audio, you should call the waveInGetDevCaps function to determine the waveform-audio input capabilities of the system. This function fills a WAVEINCAPS structure with information about the capabilities of a specified device. This information includes the manufacturer and product identifiers, a product name for the device, and the version number of the device driver. In addition, the WAVEINCAPS structure provides information about the standard waveform-audio formats that the device supports.
