- No re-encoding penalty — edit and save repeatedly with zero quality loss.
- Simple internal structure — easy to parse programmatically.
- Supports up to 32-bit float and 384 kHz sample rates.
WMA 장점
- Good quality at low bitrates (32-64 kbps) — outperformed MP3 in that range.
- Native playback on every Windows version 2000 through 10.
- Lossless variant available (WMA Lossless) for archiving.

한계점
WAV 한계점
- Enormous file sizes — 10 MB per minute for CD-quality stereo.
- 4 GB size limit for standard WAV (RF64/W64 variants extend it but break compatibility).
- No native support for cover art or rich metadata.
- Impractical for casual listening or bandwidth-constrained delivery.
WMA 한계점
- Proprietary — poor support outside Windows and Windows Media Player.

- Ecosystem abandoned — no modern editors, hardware decoders, or streaming services use WMA.
- Windows 11 deprecated Windows Media Player entirely.
