Why convert AAC to AIFF?

AAC is the successor to MP3, offering better sound quality at the same bitrate. It's the default format for iTunes, YouTube, and most streaming services — a sweet spot between size and fidelity. 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. Converting from AAC to AIFF is useful when you need audio editing in logic pro or want to take advantage of lossless, studio-grade quality.
