Power Audio Extractor is an approachable piece of kit that enables you to extract audio stream from video clips and save it to popular formats, as well as to turn audio tracks or video clips into other types. It also integrates a setting for directly downloading YouTube clips.

The installation procedure does not take a long time to finish. However, since it is ad-supported, Power Audio Extractor offers to download and install multiple third-party components, although it does need them to work properly. All these offers can be declined, though.

The interface is user-friendly, based on a window where you have to follow a few simple steps to get the job done in no time. Firstly, you can ask Power Audio Extractor to either download a YouTube video or convert a local file.

The YouTube downloader allows you to specify the preferred quality from the ones available online, as well as to establish the downloading directory. Unfortunately, Power Audio Extractor is not capable of automatically converting videos right after after retrieving them.

Batch processing is supported for the video converter, which means that you can encode multiple videos at the same time. It is also possible to indicate

the target directory, format and preset.

The list of supported formats is extensive. Common video types include AVI, MP4, FLV, SWF, MPEG, RM, WMV and MOV, while the available audio extensions are WAV, MP3, WMA, OGG, AAC, M4A, FLAC and MP2. In addition to these, Power Audio Extractor offers users the possibility to prepare media for playback on iPod, iPhone, PSP, Blackberry, iPad, Android and other mobile phone devices.

During conversion jobs, the app can be asked to play sound and automatically power off the computer on task completion. It has a good response time and carries out encoding jobs rapidly while remaining light on the system resources. There were no stability issues in our testing.

The app's downside is that it is filled with third-party program offers at installation, followed by the fact that it does not make room for audio and video configuration for the output files. The whole package seems a bit expensive when taking this into account, especially since there are other utilities which offer the same functionality (and more) for free.
