Frequently Asked Questions
What is AIFF format?
AIFF (Audio Interchange File Format) is an uncompressed audio format developed by Apple. It's essentially the Mac equivalent of WAV, storing raw PCM audio data with no compression. AIFF offers perfect audio quality but results in very large file sizes.
Will converting WMA to AIFF improve quality?
No, converting from lossy WMA to uncompressed AIFF does not recover lost audio data. The AIFF file will be much larger but contain the same audio quality as the WMA source. This conversion is useful for Mac audio production workflows, not quality improvement.
What's the difference between AIFF and WAV?
Both are uncompressed PCM formats with identical audio quality. AIFF was developed by Apple and uses big-endian byte order, while WAV was developed by Microsoft/IBM and uses little-endian. AIFF is preferred on Mac, WAV on Windows, but both work on both platforms.
Why convert WMA to AIFF?
Convert to AIFF for professional Mac audio editing in Logic Pro, GarageBand, or Pro Tools, for compatibility with Mac-based audio software, or when working in Apple-centric production environments where AIFF is the standard uncompressed format.
How much larger will the AIFF file be?
AIFF files are typically 10-15x larger than WMA files. A 5 MB WMA file might expand to 50-75 MB as AIFF because AIFF stores uncompressed PCM audio data while WMA uses lossy compression to reduce file size.
