Updated June 2026

A WMV holds its sound as compressed WMA audio, which is not what an audio editor wants. Converting WMV to WAV gives you uncompressed PCM audio, the clean, editable format that tools like Audacity, Reaper, and Premiere import without complaint. EchoWave drops the video and keeps the full audio track in your browser, free and with no signup, so you get a WAV that is ready to cut, mix, or master.

The formats

WMV vs WAV

WMV

Windows Media Video

Windows Media video, small and Windows-first

Type: Windows Media video
Holds: Windows Media video with WMA audio
Typical size: Small, built for Windows
Plays on: Windows Media Player and VLC

Best for:Older Windows video and slideshows

WAV

Uncompressed studio-quality audio

Type: Uncompressed audio

Typical size: Very large, about 10 MB per minute
Plays on: Every device and audio editor

Will it lose quality?

The WAV can only be as good as the audio already inside your WMV.
A bitrate higher than the source does not add quality, it only makes a bigger file.
192 to 320 kbps keeps music clear. 128 kbps is fine for speech.

Troubleshooting

If something looks off

The WAV has no sound

Some videos store audio as AC-3. The converter still handles it, but if a clip plays silent, re-download the source and convert again.

The file is too large to email

Convert at a lower bitrate, 128 kbps for talking, or trim the clip first to cut its length.

Which apps open WAV files?

Almost anything opens it: your browser, your phone, any music app, or VLC. No special player needed.

FAQ

WMV to WAV questions

Is the WMV to WAV converter free?

Yes. EchoWave extracts WAV audio from WMV with no signup, no file-count limit, no trial, and no watermark. Upload your video, convert it, and download the WAV from your browser.

How do I convert WMV to WAV?

Upload your WMV, choose WAV as the output format, and start the conversion. The video is dropped and the audio is saved as WAV, which you can download or open in the editor to trim.

Why is the WAV file so much larger than the WMV?

WAV is uncompressed PCM audio, so it stores every sample at full size. CD-quality WAV runs at roughly 10 MB per minute, while a WMV squeezes its sound down with WMA compression. The large size is the trade-off for lossless, edit-ready audio.

Will the WAV sound better than the audio in the WMV?

No. WAV is lossless, but it cannot rebuild detail that WMA compression already discarded inside the WMV. The WAV preserves exactly what is in the source at full quality, which is ideal for editing, but it is not a quality upgrade over the original.

Can I open the WAV in Audacity?

Yes. WAV is the standard import format for Audacity and almost every other audio editor. Convert your WMV to WAV here, then drag the file straight into Audacity, Reaper, GarageBand, or your tool of choice to edit it.

Should I use WAV or MP3 for the audio?

Choose WAV when you plan to edit or master the audio and want the cleanest source. Choose MP3 when you just want to listen or share, since it is far smaller. You can convert WMV to MP3 instead if a small, portable file is the goal.

Does the WMV to WAV converter work on Mac, Windows, iPhone, and Android?

Yes. The converter runs in any browser, so you can extract WAV from WMV on macOS, Windows, Chromebook, Linux, iPhone, iPad, and Android with nothing to install.

Does the WAV keep the full audio track?

Yes. The complete soundtrack from the WMV is converted from start to finish. If you only need part of it, open the file in the editor to trim it down before you export.

Can I convert large WMV files or several at a time?

Yes. There are no file-count limits on these pages, so you can convert your WMV files one after another. Keep in mind that WAV output is large, so longer recordings produce sizeable files.
