- Trim (Optional) — Under Trim, set a Start Time and Duration in seconds or HH:MM:SS.sss format to extract audio from a specific portion of the video.

Why Convert WMV to AIFF?
WMV (Windows Media Video) is Microsoft's video format containing both video and audio tracks. AIFF (Audio Interchange File Format) is Apple's uncompressed audio format storing PCM data. Converting WMV to AIFF extracts the audio track as uncompressed PCM, which is useful for importing video audio into Logic Pro, GarageBand, or Pro Tools for editing, extracting high-quality audio from Windows video recordings, preparing audio for CD burning on macOS, and preserving audio from video interviews or presentations without compression artifacts.
WMV vs AIFF Comparison
| Feature | WMV (Windows Media Video) | AIFF |
|---|---|---|
| Type | Video + audio container | Audio only (uncompressed) |
| Audio codec | WMA v2 (typical) | PCM 16-bit Big Endian |
| Compression | Lossy (WMA audio) | None (uncompressed) |
| File size (1 min audio) | Varies (video dominates) | ~10 MB at 44100 Hz stereo |
| Platform | Windows native | Apple native |
| Editing quality | Depends on source codec | Perfect (no compression loss) |
| Best for | Windows video playback | Music production, CD burning |
Common Use Cases
- Music production — Extract audio from WMV recordings for mixing in Logic Pro or Pro Tools
- Podcast production — Pull interview audio from WMV video recordings into uncompressed AIFF
- CD burning — AIFF is the standard uncompressed format for macOS CD burning workflows
- Cross-platform — Move audio from Windows (WMV) to Apple (AIFF) ecosystem
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 compressed audio in the WMV source.
How much larger will the AIFF file be?
AIFF stores uncompressed PCM data at approximately 10 MB per minute (44100 Hz stereo). A 3-minute audio extraction produces roughly 30 MB regardless of the WMV source quality.
Can I extract audio from a specific part of the video?
Yes. Under Trim, switch to "Trim" and enter a Start Time and Duration. This extracts only the audio from that segment, which 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 WMV to WAV instead.
What is the difference between AIFF and AIF?
AIFF (.aiff) and AIF (.aif) are the same format — Audio Interchange File Format. AIFF is the full 4-character extension, AIF is the 3-character abbreviation. Both contain identical uncompressed PCM audio.
