关于AIFF转M4A
AIFF and M4A are both Apple formats, but AIFF stores raw uncompressed PCM while M4A wraps compressed AAC or lossless ALAC in an MPEG-4 container. Converting AIFF to M4A with AAC encoding reduces file size by roughly 80% while maintaining quality that Apple considers their standard for music distribution. The M4A container supports rich metadata, chapter markers, and embedded artwork — features that AIFF handles inconsistently.
为什么要将AIFF转换为M4A？
M4A is iTunes' and Apple Music's native format. Converting AIFF to M4A integrates your audio seamlessly into the Apple library ecosystem with full metadata support, Smart Playlist compatibility, and iCloud Music Library syncing. M4A files also stream efficiently and support instant seeking through proper atom placement.
常见使用场景

- Preparing AIFF studio exports for Apple Music or iTunes Store submission
- Archiving AIFF recordings as ALAC-in-M4A for lossless storage at reduced size
- Creating M4A podcast episodes from AIFF master recordings
