Convert WMA to WAV — Free Online Converter

WMA is Microsoft's compressed audio codec, delivering lossy (Standard) or lossless (WMA Lossless) audio within the ASF container. WAV (Waveform Audio File Format) stores uncompressed PCM audio in Microsoft's RIFF container at approximately 10 MB per minute for CD-quality stereo. WAV is the universal standard for uncompressed audio across all platforms and DAWs.

Converting WMA to WAV decodes the compressed audio back to raw PCM samples, creating an uncompressed file suitable for professional editing, mastering, and any workflow that requires lossless input. For WMA Lossless sources, the conversion produces perfect PCM output identical to the original recording.

Professional audio editing tools perform best with uncompressed input. When processing WMA files through effects chains, normalizing, or mixing, the compressed format introduces latency and potential artifacts with each operation. WAV provides the clean PCM baseline that DAWs, mastering engineers, and broadcast systems expect.

WAV is also universally compatible — every operating system, audio editor, and playback device handles WAV without issue. Converting WMA to WAV removes any proprietary codec dependency and creates files that work everywhere.
