Format conversion
MKV to WAV
MKV to WAV is the way to get full-quality audio out of a Blu-ray rip, OBS recording or any other Matroska file without piping it through an ffmpeg command. VideoSplit does it client-side, downmixing surround to stereo and writing clean 48 kHz PCM.
For an MKV with a FLAC or PCM audio track, the WAV export is a lossless rewrap — no information lost at all. For MKVs with AC-3 or DTS audio, the WAV is a bit-exact representation of the decoded surround mix folded to stereo.
Step-by-step
- Open VideoSplit.io. Drop the .mkv file.
- Pick WAV. Click the WAV tag.
- Download. The 48 kHz WAV saves with the MKV's filename.
Quality and bitrate guidance
WAV files are large: about 10 MB per minute of 16-bit stereo at 44.1 kHz, closer to 20 MB per minute for 24-bit at 96 kHz. A two-hour Blu-ray rip will produce a WAV around 1.2 GB — make sure your Downloads folder has space.
Practical notes
- For archival, compress the WAV to FLAC locally with ffmpeg: `ffmpeg -i input.wav output.flac`.
- Lossy MKV sources (AAC, Opus) do not become lossless through WAV export — the source is still the ceiling.
- For Blu-ray concert rips, the WAV output can be chopped into individual song files in any DAW.
