What is a .WMA file?
WMA is Microsoft’s Windows Media Audio format.
- Did you know
- Microsoft launched WMA in 1999 to compete with MP3.
- A WMA file is really an Advanced Systems Format (ASF) container, the same wrapper Microsoft used for Windows Media Video.
- The codec was numbered to match Windows Media Player, so the first widely shipped version was “Windows Media Audio 7”.
- Microsoft later added a WMA Lossless variant that rebuilds the original audio bit-for-bit, aimed at archiving master recordings.
- The WMA, WMA Pro, WMA Lossless and WMA Voice codecs share an extension but are technically distinct and mutually incompatible.
- What Analyser shows you
- Inspect the waveform, spectrogram, codec, bitrate, channels, and tags of MP3, WAV, FLAC, M4A, AAC, OGG, and Opus audio.
- Open a .WMA file
- Drag a .WMA file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
