AIFF vs FLAC
Which audio format should you choose?
AIFF wins on lossless, studio-grade quality. FLAC wins on truly lossless compression. For most general use, pick whichever is more compatible with your existing tools — file size and quality differences are usually small at the same encoding settings.
When to use AIFF
Choose AIFF when you need audio editing in logic pro or macos-based audio production. Its strengths: lossless, studio-grade quality, and better metadata support than wav.
Pros
- + Lossless, studio-grade quality
- + Better metadata support than WAV
- + Native on macOS
Cons
- − Very large file sizes
- − Less common on Windows
- − Not suitable for streaming or sharing
