WMA is Windows' old house band: big in the early 2000s, mostly retired now. Windows Media Audio, in several variants including a rarely-sighted lossless one.

- 1999, Microsoft
- Type
- audio · lossy
- Typical size
- MP3-ish sizes; the famous 'CD quality at 64 kbps' claim never quite landed
- Plays on
- Windows Media Player and legacy Microsoft software; little else without help.
- Fun fact
- Microsoft once pitched WMA as CD quality at half MP3's bitrate: reviewers politely disagreed.
What compressing WMA actually does
WMA is already lossy-compressed, so compressing it further means re-encoding at a lower bitrate. Realistic savings run 30–70%, depending on how generous the original bitrate was: WMA typically runs MP3-ish sizes; the famous 'CD quality at 64 kbps' claim never quite landed. Squeeze too hard and you will hear it; Flippy's presets stay on the polite side of that line.

Questions people ask
How much smaller will my WMA get?
It depends on how generously it was encoded: WMA typically runs MP3-ish sizes; the famous 'CD quality at 64 kbps' claim never quite landed, and most files give up 30–70% at the medium preset before quality visibly suffers.
Will I lose quality working with WMA here?
WMA is a lossy format, so re-encoding trims a little detail each time. Work from the best source you have and convert once: at sensible bitrates the difference stays inaudible.
