关于AIFF转AAC
AIFF stores uncompressed PCM audio at full quality, consuming about 10 MB per minute of CD-quality stereo. AAC (Advanced Audio Coding) compresses that same audio to roughly 2 MB per minute at 256 kbps while remaining perceptually transparent to most listeners. Converting AIFF to AAC is the standard workflow for preparing studio masters for digital distribution — the iTunes Store, Apple Music, YouTube, and Spotify's ingest pipeline all accept or use AAC.
为什么要将AIFF转换为AAC？
Uncompressed AIFF files are impractical for distribution. A 50-song album in AIFF takes about 3 GB, while the same album in AAC at 256 kbps fits in roughly 600 MB. AAC encoding at 256 kbps (Apple's iTunes Plus quality) is audibly indistinguishable from the AIFF source in double-blind tests. Every major platform, device, and browser supports AAC playback, making it the universal distribution format.
常见使用场景
- Mastering an album from AIFF studio files to AAC for iTunes Store and Apple Music distribution
