Frequently Asked Questions
What is AIFF?
Audio Interchange File Format. Apple's version of WAV. It stores uncompressed audio with support for metadata and album art. Common in Mac audio production.
How much smaller will the MP3 be?
About 80% smaller. A 40MB AIFF file becomes roughly 7-8MB as a 320kbps MP3.
Should I use AIFF or WAV for production?
Either works. AIFF has slightly better metadata support on Mac. WAV is more universal. Both are uncompressed with identical audio quality.
Is AIFF the same as Apple Lossless (ALAC)?
No. AIFF is uncompressed (like WAV). ALAC is lossless compressed (like FLAC). ALAC files are smaller but both preserve full quality.
