Format Details
WMA
WMA (Windows Media Audio) is a series of audio codecs and their corresponding audio coding formats developed by Microsoft. It is a proprietary technology that forms part of the Windows Media framework. WMA consists of four distinct codecs: WMA, WMA Pro, WMA Lossless, and WMA Voice.
audioWAV
WAV (Waveform Audio File Format) is an uncompressed audio container format developed by Microsoft and IBM for storing raw audio data. It preserves audio at full, lossless quality with no encoding artifacts, making it the preferred format for audio production, editing, and professional archival. WAV files are larger than compressed formats like MP3, but are universally supported and suffer no quality degradation when re-encoded.
audioConverting WMA to WAV: what actually changes
WMA to WAV is one of the conversions this site performs, but the two formats are not interchangeable containers. Here is what the file keeps, what it loses, and how to get a result you can use.
What .WMA and .WAV each hold
.WMA is a audio format built for listening to or editing a recording, storing sample rate, channels and bitrate. .WAV is a audio format built for listening to or editing a recording, storing sample rate, channels and bitrate. Converting between them is a decision about which of those two jobs the result needs to do.
What changes in the conversion
Both files belong to the audio category, so this is a like-for-like repackage: the same kind of content, stored in a different container. What changes is how .WAV encodes sample rate, channels and bitrate — not what the file is about.
Quality and file size
.WMA has already discarded detail during compression, and converting to .WAV cannot bring it back. The output will be lossless from here on, so the file gets larger without recovering what the original threw away.
When this conversion is the right one
Reach for .WAV when the software, device or platform you are sending to expects it — the content is the same audio, only the packaging differs. The reverse direction works the same way, so you can always convert back from .WAV to .WMA using the same tool.
Tips for a clean WMA to WAV conversion
Start from the original file
Convert the .WMA you started with, not an earlier .WAV output. Every extra round trip costs quality and can accumulate formatting drift.
Check the real type, not the extension
Audio/x-ms-wma becomes audio/wav. If a file was renamed rather than converted, it will fail to open — rename it back to its true extension before uploading and the conversion will recognise it.
Length decides the time
Conversion runs in real terms on duration: a few seconds of media finishes almost at once, while a full-length .WMA takes noticeably longer. Upload once and let it finish rather than retrying.
Limits worth knowing
Uploads are capped per file (30 MB, or 100 MB for video) and processed temporarily — nothing is kept as a permanent copy. For huge audio files, split or compress the source first.
