WAV stores raw PCM audio with no compression, which is exactly what audio editors, samplers, and DAWs want to work with. This converter decodes your compressed WMA and writes it out as a standard WAV in your browser, free and with no signup. The result is large, around 10 MB per minute at CD quality, but it drops cleanly into any editing tool that turned its nose up at WMA.

Will it lose quality?

Converting a lossy file to a lossless one cannot restore detail that was already discarded. It only makes a larger file.
Going from a high-quality source to WAV keeps the sound clear while changing the format.
Each pass between two lossy formats loses a little, so always convert from the best source you have.

Troubleshooting

If something looks off

The WAV is larger than I expected

Lossless and uncompressed formats are big by design. If you want a smaller file, pick a lossy format and a bitrate around 192 to 256 kbps.

The song details are missing

Title, artist, and album travel as tags when the source has them. If they are blank, add them in any music app after converting.

My app will not open the WAV

Most apps open common audio, but a few are picky. VLC plays almost anything, or convert to MP3 for the widest support.

FAQ

WMA to WAV questions

Why convert WMA to WAV instead of MP3?

WAV is uncompressed, so editors and DAWs read it instantly without decoding, and you can cut, splice, and process it without stacking up another round of lossy compression. If you only need playback, MP3 is smaller, but for editing and mastering WAV is the format most tools expect.

Does converting WMA to WAV improve the quality?

No. WAV is lossless, so it preserves every detail it is handed, but it cannot rebuild anything your WMA already threw away during its own compression. The WAV will sound the same as the WMA, just uncompressed and ready to edit, so always start from the best WMA you have.

How much bigger will the WAV be?

A lot. CD-quality stereo WAV runs about 10 MB per minute, so a 4 MB WMA song can become a 40 MB WAV or more. That size is normal for uncompressed audio and is the trade-off for an editable, lossless file.

Is the WMA to WAV converter free?

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

What programs open a WAV file?

Effectively all of them. Every media player, every audio editor, and every DAW such as Audacity, Adobe Audition, Logic, Ableton, and Reaper reads WAV natively, which is the main reason people convert to it for editing.

Does the WMA to WAV converter run on Mac and Windows?

Yes. The converter runs in any browser, so it works on macOS, Windows, iPhone, iPad, Android, Chromebook, and Linux with nothing to install. That matters because most of those devices cannot open a raw WMA on their own.

Can I convert several WMA files at once?

There are no file-count limits on these pages, so you can convert your WMA files one after another. Keep in mind each WAV will be much larger than the WMA it came from, so plan for the extra disk space.

What can I do with the WAV after converting?

Drop it straight into your editor, or open it in the EchoWave editor to trim, fade, or pull out a sample before you export. WAV is the right starting point when you plan to keep editing.
