DFZ Audio Extractor

DFZ Audio Extractor is an intuitive application which gives you the possibility to extract audio streams from video clips and save them as MP3, WAV or AC3 format.
It offers support for popular video formats, including AVI, MPEG, Windows Media, QuickTime MOV, RealMedia RMVB, FLV, DVD VOB, and raw videos.

Simple installer and interface

After a fast and uneventful setup operation, you're welcomed by a user-friendly GUI, represented by a simple window with a neatly organized structure, where you can add as many videos as you want to the task list, thanks to the fact that batch processing is supported. Administrative privileges might be required at launch, in order to prevent startup errors.

Extract audio from video files

It's possible to load the audio streams in a built-in sound player, specify the output directory and preferred file type, remove any items from the list if you change your mind or clear the entire queue, as well as configure output audio parameters when it comes to the bit rate, sample rate and channel mode.

Evaluation and observations

It used a low amount of CPU and RAM in our tests, so it didn't hamper the computer's performance. However, it displayed some error dialogs when we attempted to add videos to the task list in several cases in our tests. We must also keep in mind that DFZ Audio Extractor hasn't been updated for a long time and likely has compatibility issues with newer Windows editions.

Conclusion

All in all, DFZ Audio Extractor has advanced, yet approachable options to help you extract audio from video clips to save them to MP3, WAV or AC3 file type. It offers extensive file type support when it comes to videos, and enables you to tinker with the output audio settings. However, you might encounter compatibility issues with modern Windows.
