If you have lots of video files in avi format but only need the audio part for playback on an MP3 player, this article may help you. In this post, I'd like to show you how to extract audio from avi video files and convert avi to mp3. The freeware Clone2Go Free Audio Converter can be used to convert video avi to audio mp3 in no time:
1. Download and Install Clone2Go Free Audio Converter
2. Add AVI File
Click the "Add Media Files" button to import AVI files. Alternatively, you can click "File -> Add Media Files..." to add AVI files. You can also directly drag and drop AVI files to the left panel of the program.
3. Choose MP3 as Output Format
From the "Profile" drop-down list, choose MP3 - MPEG Layer-3 Audio (*.mp3) as the output format.
4. Start Converting AVI to MP3
Click the "Start Encode" button to start to convert AVI to MP3.
Note: If you only need to extract a part of the video as mp3, Clone2Go Free Audio Converter lets you trim the video by specifying the video beginning and video end. You will then get what you need exactly, e.g. a short audio clip to be used as a ringtone for your mobile phone.
