Essa função usa o MCI (Multimedia Control Interface) para controla o drive de CD-Rom:
Public Sub RecordWave(TrackNum As Integer, Filename As String)
' Tracknum: track to record
' Filename: file to save wave as
On Local Error Resume Next
Dim i As Long, RS As String, cb As Long, t#
RS = Space$(128)
i = mciSendString("stop cdaudio", RS, 128, cb)
i = mciSendString("close cdaudio", RS, 128, cb)
Kill Filename
RS = Space$(128)
i = mciSendString("status cdaudio position track " & TrackNum, RS, 128, cb)
i = mciSendString("open cdaudio", RS, 128, cb)
i = mciSendString("set cdaudio time format milliseconds", RS, 128, cb)
i = mciSendString("play cdaudio", RS, 128, cb)
i = mciSendString("open new type waveaudio alias capture", RS, 128, cb)
i = mciSendString("record capture", RS, 128, cb)
t# = Timer + 1: Do Until Timer > t#: DoEvents: Loop
i = mciSendString("save capture " & Filename, RS, 128, cb)
i = mciSendString("stop cdaudio", RS, 128, cb)
i = mciSendString("close cdaudio", RS, 128, cb)
End Sub
