This program is a free conversion tool for AVI, DivX, and XviD files to MP3 or WAV formats. It also allows for the extraction of original audio tracks from AVI files while maintaining sound quality.

This program is completely free and allows you to extract original audio tracks from your supported files without compromising their sound quality. Additionally, you can add tags like artist, album, title, year, etc. to the generated MP3 or AAC files.
One of the program's standout features is its use of the latest version of the LAME encoder to convert audio streams to MP3. You can choose from three encoding options: constant bit rate (CBR), average bit rate (ABR) and variable bit rate (VBR).
Other notable features include the ability to extract and convert any audio track from AVI files with multiple audio tracks, customizable encoding parameters (including bitrate mode, audio bitrate, audio sampling frequency and more), and a number of predefined conversion profiles. You can even save your own settings to an INI file for easy access.
To top it all off, Pazera Free AVI to MP3 Converter is completely portable - it doesn't use system registry and all settings are stored in INI files. And with support for 18 languages and unlimited, 100% freeware use, it's both versatile and accessible.
