Frequently Asked Questions
What is AIFF format?
AIFF (Audio Interchange File Format) is an uncompressed audio format developed by Apple. It stores audio in lossless quality, similar to WAV but optimized for macOS and Apple applications.
Is AIFF better than FLAC?
Both AIFF and FLAC are lossless formats. FLAC offers better compression (smaller files), while AIFF is uncompressed and preferred in Apple ecosystems and professional audio workflows.
Will I lose quality converting from FLAC to AIFF?
No, both FLAC and AIFF are lossless formats. The conversion maintains perfect audio quality, though AIFF files will be larger since they're uncompressed.
Why are AIFF files larger than FLAC?
FLAC uses lossless compression to reduce file size, while AIFF stores audio uncompressed. Converting FLAC to AIFF will result in larger files but maintains the same audio quality.
What applications support AIFF?
AIFF is natively supported by all Apple applications including iTunes, Logic Pro, GarageBand, and QuickTime. It's also supported by most professional audio editing software.
