About Matroska (MKV)
Matroska (MKV) is an open container format that can hold almost any video and audio codec, any number of audio and subtitle tracks, chapters and attachments.
It is popular for films and series with several audio languages and subtitle tracks, and for archiving video.
Many phones, browsers and TVs do not play MKV files directly, even when they support the codecs inside.

Why won't my MKV file play on my TV or phone? Most TVs and phones play MP4 or H.264 but not the Matroska container, so converting to MP4 makes the file playable on almost any device.
About WAV
WAV (Waveform Audio File Format) is a Microsoft and IBM container that normally stores uncompressed PCM audio.
Recording, editing and mastering, where every sample has to be kept exactly.
Uncompressed audio is large, about 10 MB per minute of CD-quality stereo, and a classic WAV file is limited to 4 GB.
Why convert audio to WAV? For editing and mastering: uncompressed samples take further processing without new loss, and every audio program reads them.
What changes when you convert MKV to WAV
- The soundtrack of the MKV is re-encoded as WAV at the default settings, so it is close to the original but not bit-identical.
- Only the sound is kept: the WAV file contains the audio track of your MKV, and the picture is dropped.
- WAV output is written as 16-bit PCM, so audio with a higher bit depth, such as 24-bit, is reduced to 16 bits.
