What is WAV?
WAV stores audio as uncompressed PCM, exactly as it was recorded. That makes it the standard for recording, editing and mastering, where no quality can be lost, but a WAV file is about ten times larger than the same audio in MP3.
What is MKV?
MKV (Matroska) is an open, royalty-free container that can hold any number of video, audio and subtitle tracks plus chapters in a single file. It is popular for films and archives, but many phones, TVs and editors do not open it natively.
Tips for converting WAV to MKV
- Converting a compressed file such as MP3 to a lossless format does not restore detail already removed; it only makes the file larger.
- For music, a lossless source (WAV or FLAC) gives the best result when you convert to MKV.
- Check that your player, car stereo or editing app supports MKV before converting a whole library.
- Keep the original WAV file as a backup until you are happy with the converted audio.
