What is MP3?
MP3 files represent the MPEG 1 Audio Layer 3 technology and audio file format that is used to compress and save music. It is one of the most common file types in use. It is a lossy form of data compression and was developed by the Moving Picture Experts Group. An MP3 file is actually only a fraction of the size of a CD track. CD tracks can be as large as up to 40MB depending on the length of the recording/song where as an MP3 of the same recording or song will be exceptionally small.
The MP3 format compresses audio files. The algorithm that is used to compress a raw audio file or a CD track discards audio information that will not significantly affect the quality of the track. The information that is discarded includes sounds that cannot be heard by the average person, low sounds that will not be heard over a louder sound that is being played over it, and keeping certain sounds that the human ear is more perceptive to while discarding the ones that are likely to be ignored.
What determines the quality of an MP3 file is the bit rate that it was converted to. The higher the bit rate, the bigger the file and the better the quality. The lower the bit rate, the smaller the file and the more loss there will be loss in sound quality.
How to open an MP3 file online?
Although MP3 is a lossy compressed audio format it’s also one of the most common audio file types found online. You can upload an MP3 file to Jumpshare and play it. The MP3 file viewer has the basic play/pause button, a seek bar that you can use to jump to a different point in the track, and volume controls.
