Part 8: How to Upload MP3 to YouTube

What is MP3 Format?

MP3 is also known as the MPEG-1 Audio Layer. Created by the Moving Pictures Expert Group, this format uses the lossy algorithm to store and play audio clips, thereby effectively reducing the storage space needed to compile the file without affecting the quality of sound too much.

The popularity of this file format was and still is phenomenal over the internet. It is currently the format of choice as far as music files are concerned. It is also the type of file most shared over a peer-to-peer network. When the ripping of CD’s to create MP3 files became possible, many record companies claim that such an act is a copyright infringement.

An MP3 file is predominantly characterized by its bit rate. The higher the bit rate, the closer the output will be to the original sound. However, an MP3 file with a higher bit rate would also mean a bigger data file.

Upload MP3 to YouTube
