Rip Audio from a CD and More

Environment: VC6, MFC, Win95/98/NT/2000/XP

This software will record music from various sources, including “ripping” an audio CD. This is a freeware software. It is used to record audio CD music, cassette tape music, and other external sources. However, the output format is the pure WAVE format that is the Windows standard.

It has basically no menus, as all the operations are simple and in a dialog box. The Options button is the important one. You should specify the options before you begin recording. The Options dialog box requires you to specify a folder where the recorded files are to be stored. For audio CDs, the files are stored by their track names with a .WAV extension. However, for outside sources, the files are stored as Sound.Wav. You must rename this file to your own filename before you begin the next recording; otherwise, the file is overwritten!

The music is converted to a wave file by using low-level multimedia functions in Win32. You must specify the resolution of the recorded file. CD-quality recording is 11025 X 4, stereo, 16 bits per second. If you specify another resolution, the audio quality is degraded but the files consume less memory. For example, 11025 X 1, mono, 8 bits is the lowest resolution; it is telephone quality, occupying only 11025 bytes per second! Depending upon your needs, you can specify other resolutions. The music ripping application looks like the follwing:

There is a temporary memory parameter, which is the maximum amount of memory used for recording instead of using minutes and seconds; it does an automatic calculation of the amount of memory available. This can be used if you are unable to specify the amount of time. The memory allocated can succeed only if you specify a large amount of paging file, which is the virtual memory.

If you get a memory error while starting to record, try reducing the resolution in the Options dialog box. Select the audio CD drive to get a listing of the files in it. Then, select a song and press the Rip AudioCD button. If you are recording from a cassette tape or other sources, use the Rip Other button. The + button next to the CD drive selection box is used to refresh the drive.
