Creating an MP3 file is a two-step process: ripping and encoding.
- Ripping means placing your musical CD - the latest by John Mayer, for example - into your computer's CD or DVD-ROM drive and telling the software to copy a song or songs into huge files onto your hard drive.
- Encoder software then compresses those huge files (known as WAV files on the PC and AIF files on the MAC) into the much smaller MP3 format, letting you delete the original recording.
Most all-in-one MP3 players, such as Musicmatch Jukebox or Apple's iTunes, rip and encode in one step. Just insert the CD, and, after a few minutes, your MP3 files appear on the hard drive.
MP3 files aren't always created from CDs, although that's the easiest method. You can turn any recording into an MP3 file by connecting a few wires from the back of your home stereo's amplifier to your computer's sound card.
To rip songs from a CD, start the ripping application of your choice, insert the CD, choose the songs you want to rip, and click the software's Copy or Record option. The software grabs the Compact Disc Audio (CDA) straight from the CD as a WAV file and then encodes it as an MP3 file and saves the sound on your hard drive. Note that ripping (technically known as digital audio extraction) doesn't work on the oldest of CD-ROM drives. If your drive can't perform digital audio extraction, it's time to buy a new one.
You don't even need a sound card; the CD's music (which is already stored on the CD using numbers to represent the sounds) becomes numbers on your hard drive.
As you wander into the wonderful world of ripping songs from a CD, keep these points in mind:
- Some ripping programs need lots of room to work. If your hard drive lacks at least 600MB of free space, rip the songs one at a time.
- Bought a blazingly fast 52x speed drive? It'll never rip audio that quickly. That rating indicates how fast the drive reads a CD's information. Rippers need a CD to send data.
- Immediately after ripping a CD, listen to the MP3 files in Musicmatch Jukebox or Winamp. If the sound has skips, pops, unwanted noise, or other distortion, set the software to rip at a lower speed.
