Before you begin:
This class is able to record audio input from playback devices like Wave, Microphone etc. It implements methods
OpenDevice
CloseDevice
StartRecording
StopRecording
CreateWaveFile(cFilename)


Some parameters are hard-coded: max recording time, bits per sample, samples per second and channels. Though it is easy to make this basic class more flexible.

My comment:
Yet another reason to wish threads and callback functions to be supported in VFP -- the waveInProc callback function can provide a smooth transition to the next memory block while the previous one being written to a file and released.
