FAQs About MP3 Files

Music lovers of a certain age, who remember vinyl records and heavy-duty turntables, often have little online-music know-how, which is limited to opening iTunes, clicking a favorite song, and pushing the play button. It is 2011, and the music world is a millennium beyond these decades-old dinosaur devices. Streaming internet is today’s most common multimedia on the net, and MP3 files (Moving Picture Experts Group, Audio Layer III) are widely supported by all kinds of audio digital content. Learning just a few things about MP3 files increases your knowledge and enjoyment of the array of music available on your personal computer.

Q: What is an MP3 file?

A: The MP3 (MPEG-1 Audio Layer-3) is a high-tech format that compresses sound into a smaller file utilizing fractal-derived algorithms. Large audio files are made smaller, and easily transferable across the net. One second of CD music includes 1.4 million bits of data, which is reduced 12 times in a typical MP3 file.

Q: If MP3 files are compressed, does that mean they are not as good as the original recording?

A: Individual MP3 files generally reduce some quality of the originally recorded sound. Individual files compress at different rates; typically, higher compression rates render lower sound quality. Most quality MP3 files are compressed at a ratio of 10:1 (1 MB per minute of digital music).

Q: How are MP3 files played on a computer?

A: Unlike streaming audio, MP3 files are usually available in download format, and open with one of the many popular MP3 players, including Winamp, RealPlayer and iTunes. Most personal computers include already-installed audio players in their operating systems.

Q: Where are MP3 files found on the internet?

A: MP3 sound files are available anywhere music is a featured product, or part of the entertainment menu. MP3 “rip” programs are inexpensive or free, available online, and easily create an MP3 file from any selection on a personal CD. There are even online software downloads to convert old 78s and eight-track cassettes into MP3 files. In other words, understanding a few simple basics about MP3 files opens up a brand new online world of music, for even the oldest old-timers.
