X2X Free Audio Converter, as the name implies, is a free audio converter that can extract audio from multiple video formats, such as, AVI, MPEG, MOV, MP4, RM, RMVB, ASF, QT, 3GP, 3G2, AMV, FLV, and many more. There are quite some tools which can convert videos into mp3 audio but this application takes it further ahead by giving users the choice of selecting the audio format to convert into.
Apart from the popular MP3 audio format, it supports AAC, WAV, WMA, and OGG. The interface has been build keeping batch conversion and simplicity in mind. Hit Add to begin adding video files in the application window, now choose the output format, quality, and destination. There are four presents; High Quality, Optimal Quality, Standard Quality, and Economy Quality. When all settings are ready, hit Convert to begin the extraction.
Most of the advanced options are located in Settings, such as, Output Name where you can choose the name prefix and postfix, Trim where you choose the portion of the video that you want to extract, and Tags which allow you to set the tags of the output audio file.
To test this app we added a 885MB video in AVI format which took only 20 seconds to convert to MP3 format on standard quality. The output quality came out to be pretty good with file size of only 9.10MB.
The applications works on Windows XP, Windows Vista, and Windows 7. We tested it on Windows 7 32-bit OS.
