Convert MKV to WAV — Free Online Converter

WAV (Waveform Audio) stores uncompressed PCM audio, making it the universal standard for professional audio editing across every platform. Extracting audio from MKV to WAV gives you raw, unprocessed audio data that any DAW, audio editor, or production tool can import without codec concerns.

Professional audio workflows in film, television, music production, and game development universally accept WAV as their interchange format. When pulling audio from MKV video recordings for post-production work — whether it is dialogue editing, Foley synchronization, or music mixing — WAV is the safe format that never requires codec installation or causes compatibility surprises in any tool from Audacity to Pro Tools to Reaper.

WAV is also the required format for many distribution standards. CD mastering requires 16-bit 44.1 kHz WAV, broadcast audio standards (EBU R128) specify WAV as the delivery format, and most sample libraries (Kontakt, EXS24) expect WAV files. If your source audio is locked inside an MKV container, extracting to WAV makes it immediately usable in these professional contexts.

FFmpeg decodes the MKV audio stream (any codec) and outputs raw PCM samples in little-endian format within a WAV container. The default output is signed 16-bit integer PCM at the source sample rate, but 24-bit, 32-bit integer, and 32-bit float are also available. Multi-channel audio (5.1, 7.1) is preserved in the WAV output with standard channel ordering. WAV supports sample rates up to 4 GHz and file sizes up to 4 GB (or unlimited with WAV64/RF64 extensions).
