This software program supports a pretty large number of file types at import, such as AVI, FLV, MP4, MOV, AAC, M4A, MP3, AC3, ASF, WMV and WAV, while export is only available in MP3, WAV, OGG, FLAC and WMA formats. All of these can be uploaded with the help of an incorporated file browser, as well as the “drag and drop” function.

It is possible to play all added files with the help of the built-in playback buttons, while you can also choose the start and end time, thus trimming the length of the item. Aside from that, you can also tweak a pretty wide range of parameters, depending on the output extension.

To be more precise, when it comes to MP3 files, you can adjust the bit rate, channel and tag it as copyright, original and private, while WMAs enable you to change frequency, channels and nominal bit rate. FLAC items can only have different levels of quality (8 being the best), and OGG files support tweaks at frequency, channels, bit rate, and quality.

To conclude, Kastor – Free Audio Extractor is a pretty efficient and reliable piece of software when it comes to converting videos to songs.
