AIFF vs MP3
Which audio format should you choose?
AIFF wins on lossless, studio-grade quality. MP3 wins on universal support on every platform. 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
