About AC3, DTS and other movie audio

Films and TV recordings in MKV often carry Dolby Digital (AC3), E-AC3 or DTS surround tracks meant for home cinema systems. Headphones, phones and car stereos cannot always play these. MP3 converts the track to standard stereo that any device can play, while Original track in the Extract Audio tool keeps the surround audio untouched.
