Why convert WAV to AIFF?
You have a WAV file that will not open on one of your devices or applications. AIFF is more widely supported for your use case: Logic Pro, GarageBand, mastering.
How to do it, step by step
- Drop your WAV fileinto the area at the top of the page (or several files at once). On mobile, tap the area and pick the file from your apps.
- Check the output format: AIFF is already selected. AIFF is a lossless format: there is no quality setting, the sound is reproduced identically. The file will be noticeably larger than a compressed format.
- Start the conversion.The FFmpeg engine loads once (≈ 10 MB), then each file is processed in a few seconds without leaving your device.
- Download your AIFF, directly or as a .zip if you converted several files. The name and metadata (title, artist, cover art) are preserved.
The WAV format (Waveform Audio File Format)
WAV is an uncompressed format: it stores raw audio, exactly like a CD. The quality is perfect but the files are large (about 10 MB per minute at CD quality). It is the reference format for audio editing, music production, transcription and professional software.
- No quality loss
- Read by every audio application
- Ideal for editing and transcription
- Very large files
- No standardized metadata (title, artist)
The AIFF format (Audio Interchange File Format)
AIFF is Apple's equivalent of WAV: uncompressed audio, perfect quality, large files. It is produced by Logic Pro, GarageBand and iTunes (CD import as AIFF). Outside the Mac, it often causes playback problems.
- Lossless quality
- Supports metadata (unlike WAV)
- Very large
- Rarely played outside the Mac
