What is an MP 3? MP 3: MP 3 is an acronym for MPEG-1 What is an MP 3? MP 3: MP 3 is an acronym for MPEG-1 or MPEG-2 audio layer 3. MP 3 is the file extension for MPEGaudio layer 3. Layer 3 is one of three coding schemes (layer 1, layer 2 and layer 3) for the compression of audio signals.

I know 1 gig is 16 hours of audio files, but mp 3 files are condensed. Right? Someone help please!!! Answer: The audio files are already compressed as you said they are in mp 3 format. You say they are on 8 cds. They must be highly compressed to fit that much only 8 cds. A cd has 700 MB of storage. You have 8 of them. Do the math and that equals about 5. 6 GB. If that's the case, you should probably get something that is at least 8 GB. Go with 16 GB if you plan on adding more. • http: //reviews. cnet. com/4520 -7964_7 -5134106 -3. html? tag=bg; bg_l
