WAV is sound only, so it will not drop into a slideshow, a Windows video project, or any tool that expects a clip. Converting WAV to WMV wraps your audio in a Windows Media video with a simple visual, which is handy when you are working inside older Windows software that prefers WMV. Your sound is carried across at full quality, and you can add a cover image or waveform in the [editor](/video-editor/) first. Free in your browser, with no signup and no watermark.

Will it look and sound right?

Your audio is kept at full quality inside your new WMV video, so nothing is lost from the sound.
The picture is a simple visual because the source is audio only. Add a cover image or waveform in the editor for a richer look.
A longer track makes a larger video, since the file carries a picture for every second.

Troubleshooting

If something looks off

The video is just a still image

That is expected, since the source is audio only. Open the WMV in the editor to add a cover image, logo, or animated waveform.

It will not upload to YouTube or Instagram

Most sites want MP4. Convert to MP4 for the widest support, then upload the video file.

The file is large

Video files are bigger than audio because they store a picture for every frame. A shorter track or a plain background keeps the size down.

FAQ

WAV to WMV questions

Why turn a WAV into a WMV?

WMV is a video format, so it works where a plain WAV cannot, such as PowerPoint, Movie Maker, and older Windows tools that want a Windows Media video. Wrapping the audio in a WMV gives those programs the clip they expect while keeping your sound.

Will the WMV just show a still image?

By default it shows a plain background because the source is audio only. To give viewers something to look at, open the WMV in the editor and add cover art, a logo, or an animated waveform that moves with the sound.

Should I use WMV or MP4 for the video?

Pick WMV when you are staying inside Windows Media Player or older Windows software that prefers it. For sharing online or playing on phones and Macs, MP4 is the more universal video format and the safer choice.

What plays the WMV after converting from WAV?

Windows Media Player opens WMV natively, and VLC plays it on any system. Macs, iPhones, and Android devices do not always handle WMV by default, so convert to MP4 if you need it to play outside Windows.

Does converting WAV to WMV change the sound?

Your audio is carried into the WMV so the recording sounds the same as the WAV did. The video layer sits on top and does not alter the underlying sound.

Why is the WMV larger than my WAV?

A video file stores a picture for every second of playback, which adds size on top of the audio. A longer track or a busy moving background makes a bigger WMV, while a plain still image keeps it smaller.

Is the WAV to WMV converter free?

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

Does the converter work on Mac as well as Windows?

Yes, the converter runs in any browser on macOS, Windows, Chromebook, and Linux. Playing the finished WMV is easiest on Windows, so use VLC or convert to MP4 if you need it on a Mac.
