Why Convert WMA to AIFF?
WMA (Windows Media Audio) is Microsoft's proprietary audio format. AIFF (Audio Interchange File Format) is Apple's uncompressed audio format that stores PCM data — the same quality as a CD. Converting WMA to AIFF is useful for importing Windows audio into Logic Pro, GarageBand, or Pro Tools for editing, preparing audio for CD burning on macOS where AIFF is the standard, moving audio from Windows to Apple workflows without further quality loss, and preserving WMA audio in an uncompressed format for archival.
WMA vs AIFF Comparison
| Feature | WMA | AIFF |
|---|---|---|
| Developer | Microsoft | Apple |
| Compression | Lossy (proprietary) | Uncompressed (PCM) |
| Audio codec | WMA v2 | PCM 16-bit Big Endian |
| Typical bitrate | 64-320 kbps | ~1411 kbps (CD quality) |
| File size (1 min, stereo) | 0.5-2.4 MB | ~10 MB at 44100 Hz |
| macOS support | VLC only | Native |
| Editing quality | Degrades on re-encode | No degradation |
| Best for | Windows playback | Music production, CD burning |
Common Use Cases
- Music production — Import WMA files into Logic Pro or GarageBand as uncompressed AIFF for editing
- CD burning — AIFF is the standard uncompressed format for macOS CD burning workflows
- Cross-platform — Move audio from Windows (WMA) to Apple (AIFF) ecosystem
- Archival — Store audio in uncompressed format to prevent future quality loss
Why is the File Compression section not available?
AIFF is an uncompressed PCM format — the default codec is PCM 16-bit Big Endian (PCM_S16BE). There are no compression options because the audio is stored as raw, uncompressed data. The output file will be significantly larger than the WMA source.
Will converting WMA to AIFF improve quality?
No. Converting from lossy WMA to uncompressed AIFF preserves the current quality but cannot recover data already lost by WMA compression. The benefit is that the AIFF version won't lose any additional quality during editing or re-saving.
How much larger will the AIFF file be?
A 3 MB WMA file (3 minutes at 128 kbps) becomes roughly 30 MB as AIFF at 44100 Hz stereo. AIFF stores uncompressed PCM data at approximately 10 MB per minute.
Can I trim the audio during conversion?
Yes. Under Trim, switch to "Trim" and enter a Start Time and Duration. This extracts a specific segment and also reduces the output file size.
Does AIFF work on Windows?
Yes. AIFF files play on VLC, foobar2000, and most audio editors on Windows. However, WAV is the more common uncompressed format on Windows. For Windows-native workflows, consider WMA to WAV instead.
