Opening Waveform-Audio Input Devices

Use the waveInOpen function to open a waveform-audio input device for recording. This function opens the device associated with the specified device identifier and returns a handle of the open device by writing the handle of a specified memory location.

Some multimedia computers have multiple waveform-audio input devices. Unless you know you want to open a specific waveform-audio input device in a system, you should use the WAVE_MAPPER constant for the device identifier when you open a device. The waveInOpen function will choose the device in the system best able to record in the specified data format.
