Part One: Audio Conversion Software: What Else To Look For
Although the main purpose of audio conversion software is to change audio files from one format to another, these programs have other feature sets that can be useful when you are looking to manipulate audio.
Extract Audio From Video
Software that can take audio from anywhere saves you time. If you want to use the audio tracking from a video file, you don’t need to use a separate program to extract the audio from the video file, then import it into your audio converter. Audio conversion software that can pull audio straight from a video file and convert it within the same interface simplifies the process. All of the programs we reviewed have the ability to extract audio from video files, but our top programs are compatible with many video formats while others are only compatible with a handful of them.
Extract Audio Data From CDs
CDs are quickly traveling down the same road to obsolescence that cassette tapes and vinyl records wandered down decades ago. Audio conversion software that allows you to rip your CDs right within the program saves your audio in a more useful format. Not all programs we reviewed allow you to rip CDs straight into the program. Switch, Xilisoft and Stellar are among the few that allow you to complete this task. From here you can choose to compress the file to create more storage or save your file as a lossless audio file that retains CD quality.

Other Audio Converter Software: Our Verdict – From toptenreviews.com
Switch is the Top Ten Reviews Gold Award winner. It is compatible with the most files and can convert to more file formats. Switch can also extract audio data from CDs as well as every video file format we tested. It’s one of the few programs that is available on both PC and Mac platforms and is the top performer in terms of conversion speed.
Xilisoft is the Silver Award winner. This audio converter is one of the most user-friendly on the market. Like Switch, Xilisoft converts all of the video formats we tested and has the ability to rip audio CDs. Xilisoft is much slower at compressing audio files compared to the competition, and it falls in the middle of the pack in terms of file compatibility. It is one of the few conversion programs that work on both Mac and PC platforms.
Stellar Audio and Video Converter is the Top Ten Reviews Bronze Award winner. It features many of the same capabilities as our Gold and Silver Award winners, but it is only compatible with seven different file formats – far fewer than all of the other audio software products that we reviewed. However, this software compresses files in a timely manner and is available on PC platforms.
