WMV to WAV Optimization FAQ
How do I extract the audio from a WMV file as WAV?
+
Upload the WMV file and we demux the audio track, then transcode it to WAV. There is no second video pass and no quality loss beyond what the WAV codec itself introduces.
What audio bitrate does the WAV file use?
+
A lossy WAV is encoded at 192 kbps by default. The Audio Quality setting also offers 320 kbps for the best quality and 128 kbps for a smaller file. A lossless WAV (WAV, FLAC) ignores the bitrate and keeps every sample.
Will I lose audio quality going from WMV to WAV?
+
If WAV is lossless (WAV, FLAC), every sample is preserved exactly. If WAV is lossy (MP3, AAC, OGG, Opus), the WAV codec recompresses — at 192 kbps this is transparent for almost all content. Recovering quality that was already gone in the WMV source is impossible.
Does the extracted WAV keep the original sample rate?
+
By default yes — a 48 kHz audio track in WMV becomes 48 kHz in WAV. If you need 44.1 kHz (CD-quality) for compatibility with older players, the advanced options expose a sample-rate dropdown that resamples with a high-quality filter.
Can I extract audio from multiple WMV files to WAV in one batch?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
How long does extracting WAV from a WMV file take?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
Can I extract just a section of the WMV audio as WAV?
+
Not in this single tool — extract the full audio as WAV here, then use /audio-trim/ or /audio-cutter/ to clip the section. The two-step path is faster than a combined operation because we avoid re-decoding the whole file twice.
Is my WMV file private during audio extraction?
+
Yes. Uploaded WMV files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted WAV are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Why does my WAV file have silent gaps?
+
Usually the WMV carries more than one audio track and the one that was converted is silent or secondary. The converter picks one audio track automatically, normally the main one, and this page has no setting to choose a different track. If the wrong one comes out, remux the WMV with the track you want first (VLC or ffmpeg can do this) and convert it again.
Does the extracted WAV play on iPhone / Android / car stereo?
+
MP3 plays almost everywhere. AAC plays on Apple devices, most Android phones and Sonos. OGG and Opus need a recent player on iOS but play in Chrome, Firefox and VLC. There are no device presets on this page, so choose the target format your player supports.
