Convert WMV to WAV — Free Online Converter

WMV files contain WMA audio inside Microsoft's ASF container. WAV (Waveform Audio) is also a Microsoft format — a simple RIFF container holding uncompressed linear PCM audio. WAV is the most universally compatible audio format in existence: every operating system, DAW, audio editor, and media player on every platform can read WAV files without codec installation. Converting WMV to WAV extracts the audio track and stores it as uncompressed, lossless PCM — the gold standard for audio editing and mastering.

WAV is the universal interchange format for professional audio. When you need to extract audio from WMV for editing in Audacity, Pro Tools, Adobe Audition, FL Studio, Ableton Live, or any other DAW, WAV requires zero import conversion — it opens instantly with full waveform display. WAV is also the mastering format for CD production and the standard for sample libraries, sound effect databases, and broadcast audio.

FFmpeg opens the ASF container, decodes the WMA audio stream to raw PCM, and writes it into a WAV container with the standard RIFF header. The sample rate (44.1/48/96 kHz), bit depth (16/24/32-bit), and channel layout from the source are fully preserved. If the WMV uses WMA Lossless, the WAV output is bit-perfect. For standard WMA, the decoded PCM represents the full quality of the lossy source.
