Compressing copies of CD tracks to use less disk space
|
A typical CD can hold several hundred megabytes of information. When copying CD tracks to your computer, you generally do not want to use as much disk space for the tracks as is available on the CD. To use less disk space, you can compress CD tracks when you copy them to your computer. However, some audio quality is lost when the track is compressed. The better the audio quality when a track is copied, the more disk space is required.
Windows Media Player automatically compresses CD tracks when you copy them to your computer; otherwise, one CD would use hundreds of megabytes on your computer.
The following table shows the range of disk space used for different audio qualities:
Quality | Bit rate | Disk space* |
Smallest Size | 48 kilobits per second (Kbps) | 22 megabytes (MB) |
Small | 64 Kbps | 28 MB |
Medium | 96 Kbps | 42 MB |
Medium-high | 128 Kbps | 56 MB |
High | 160 Kbps | 69 MB |
Best Quality | 192 Kbps | 86 MB |
*Refers to the amount of disk space required if you copy an entire CD according to quality level.
