Professional MKV to FLAC Extractor: Extract FLAC from MKV Easily


Before converting MKV to FLAC, we need to know what MKV and FLAC are separately.

What is MKV?

MKV, short for Matroska Multimedia Container, is an open media container, which can hold a large amount of video, audio, picture or subtitle tracks inside a single MKV file. The aim of MKV is to work as a universal format for storing common multimedia content, like movies or TV shows. Different from other media containers like AVI, MP4, ASF, etc., MKV is totally open in specification.

What is FLAC?

FLAC is the short form of Free Lossless Audio Codec, and as its name implies there will be no quality loss in the compression of audio data. Different from the lossy audio format like MP3, AAC, or Vorbis, FLAC will never remove information from the audio stream. To compress audio sources to FLAC, you can reduce in size 40 to 50 percent. Although incompatible to many media players, because of its open source nature, FLAC is well supported by many software applications.
