Why convert AIFF to FLAC?
AIFF is Apple's uncompressed audio format, equivalent to WAV but with better metadata support. It's the standard for professional audio work on macOS and a common output of Logic Pro and Final Cut. FLAC is an open-source lossless audio format that compresses files by 30–60% with zero quality loss. It's the favorite of audiophiles and music archivists who want CD-quality sound without the bulk of WAV. Converting from AIFF to FLAC is useful when you need high-resolution music libraries or want to take advantage of truly lossless compression.
