MKV is a container format for audio and video files. MKV can contain almost an infinite number of audio and video files in just one single file. However, technically nobody puts an infinite number of media files while encoding a MKV file but still MKV movie files are larger in size than standard formats like MP4, AVI etc. This is the reason why larger MKV movie files remain incompatible with many devices like home theaters, and TVs.

Some of these deviceswon’t play the video but give out only sound while some of them produce the video on the screen but no sound. But if you don’t want to watch the video at all then it would be better to convert it to MP3 format. Because MP3 is universally supported by all multimedia devices and you just have to listen to the movie instead of watching it. So, in this tutorial I will teach you to convert MKV to MP3.
