Q119591 How to Obtain Microsoft Support Files from Online Services

Microsoft used the most current virus detection software available on the date of posting to scan this file for viruses. Once posted, the file is housed on secure servers that prevent any unauthorized changes to the file.



Four pieces of sample code included with this article create four applications: PLAYACD, a simple CD controller; SINGACD, a sing-along application that shows the lyrics to a CD as it plays; TIMEACD, an authoring tool to create the lyric files used by the sing-along application; and SINGAWAV, an application that demonstrates synchronizing to a waveform.

The SINGACD sample application shows how to use the media control interface (MCI) to synchronize an application with CD audio in Microsoft(R) Windows(TM).

SINGACD displays a moving ball above the lyrics of a song. The ball moves in time with the music and (ideally) stays above the current word in the song. Achieving this synchronization involves a two-part process: The first part involves displaying the entire line of text at the right time; the second part involves placing the ball over the correct word in the line.

SINGACD has the following components:

  • The PLAYACD application is a very simple controller for the MCI CD audio device.
  • The TIMEACD application is a tool for authoring lyric files.
  • The SINGAWAV sample is a modified version of SINGACD that opens and plays a specific wave file and lyric file.
