Power Audio Extractor can extract any audio stream from your videos. The program can also be used as an audio converter, as it can change audio formats. You are even able to convert an audio file into a video stream that, of course, will not display any image. Thus, either from an audio or from a video file, you can easily have the existing audio in formats that you can play in your portable device or your favorite media player.
Power Audio Extractor will let you load almost any video or audio file. The program can process several files at once. Then, you will have to choose the format and the quality that you want the target file to have. There are several built-in presets to choose from, depending on the destination format. You can define an output directory, or let the program save your file in the default one. When you click on the "Convert" button, the program begins the extraction.
Power Audio Extractor’s trial version will let you perform nine audio extractions. After that, you will need to register it.
