How do I play an MP-3 file

The minimum requirement of hardware for an acceptable music quality is a Pentium 75. All one needs to do is to either convert from CD audio to MP-3 by using a CD ripper program that grabs audio tracks from a CD and converts them into wave-file format, or from MP-3 to CD audio.

MP-3 decoders are programs that convert MP-3 files into a wave file (WAV format)

using a decompression algorithm. But many MP-3 players can also decode MP-3 files
