Frequently Asked Questions
What is MKV format?
MKV (Matroska) is a free, open-source multimedia container format. While commonly used for video, MKV can also store audio-only content with advanced features like multiple tracks, chapters, subtitles, and rich metadata. It's highly flexible and supports virtually any audio codec.
Why put audio in an MKV container?
MKV offers advanced features for audio: multiple audio tracks (different languages/versions), chapter markers for audiobooks, embedded cover art and metadata, subtitle tracks, and attachments. It's ideal for complex audio projects, archival, or when you need features beyond what standard audio formats provide.
What's the difference between Copy and PCM codec?
Copy codec preserves the original WAV audio data without re-encoding (fastest, lossless, maintains exact quality). PCM (pcm_s16le) re-encodes the audio as uncompressed PCM in the MKV container (also lossless but re-encoded). Both are lossless - use Copy for faster conversion and identical data preservation.
Will I lose quality converting WAV to MKV?
No, using Copy or PCM codec is completely lossless. MKV is just a container format - the audio quality depends on the codec used. With Copy, the audio data is identical to the original WAV. With PCM, the audio is re-encoded but remains lossless. Both preserve 100% of the audio quality.
Is MKV audio compatible with media players?
MKV has excellent support in modern media players like VLC, MPC-HC, and Plex. However, many portable devices, phones, and car stereos don't support MKV. For maximum compatibility with consumer devices, use MP3, AAC, or M4A instead. MKV is best for archival and specialized use cases.
