How to Convert AVI to MP3

If you’re looking to convert AVI videos to MP3s and play on your MP3 player, I will tell you one approach, But before we move on to cover how to convert the files, let’s go over the main differences between MP3s and AVIs.

• MP3 (MPEG-1, Layer 3): MP3s are small, high quality audio files that can be played on MP3 players or software. MP3s can be easily created using a home computer, a ripper program that copies a song from a CD to your computer, and an encoder that converts your music to MP3 format.

• AVI (Audio Video Interleave): This is a container video format that specifies certain structure how the audio and video streams should be stored within the file. AVI itself doesn't specify how it should be encoded (just like the streaming format ASF), so the audio/video can be stored in very various ways. Most commonly used video codecs that use AVI structure are M-JPEG and DivX. AVI contains code called FourCC which tells what codec it is encoded with.

Generally speaking, MP3s are for audio files used on MP3 players and software, and AVIs are for audio/video files used for internet streaming and high tech cell phones.
