This is a very simple process and can be done using the GSpot Codec Information Tool. Just download the program and install it. Now go into your Start Menu and open the program.
- Select File | Open and select your AVI file
- Look for the section labeled Audio Codec
- You will see the name of the Audio Codec you need download.
- You can now go to that developer’s website to download your codec. You can also visit the Codec section of wmplugins.
Note: Do not download anything labeled as a “Codec Pack”. This will help you stay out of trouble when playing your files.
