To MP3 Converter separates and transforms to MP3 format ALL audio streams from a video (excluding VOB files). Some video files, such as MP4, WMV, AVI and MKV contain few audio tracks. It could be multiple languages tracks or audios for various types of hardware.  The majority of MP3 encoders capture only single audio track – that is defined as major by the movies’ creators. Even so, if you would like to extract all audio tracks from a video, you have to use a special application. To MP3 Converter is an ideal tool for such occasion – it rips every audio stream from a video. Thus, you only have to choose – which audio stream you prefer, since you will possess all of them.


To convert media files to .mp3 format simply select a destination folder and drop your files or folders to the app’s icon or interface. Converter advises when processing is made and if there are any failures. Conversion is done with full utilization of existing CPU cores and also it is “crash free” due to the use of external processes.
