关于AAC转AIFF
AAC delivers excellent audio quality at compressed bitrates, powering iTunes and YouTube. AIFF (Audio Interchange File Format), created by Apple in 1988, stores uncompressed PCM audio at full CD quality or higher. Converting AAC to AIFF decodes the compressed AAC data back to raw PCM samples, producing a lossless file suitable for professional editing in Logic Pro, GarageBand, or Pro Tools on macOS.
为什么要将AAC转换为AIFF？
Professional audio editors require uncompressed input to avoid compounding artifacts during processing. When you apply effects, normalize levels, or time-stretch audio in a DAW, starting from a compressed AAC file causes generation loss with each edit cycle. AIFF provides the uncompressed PCM baseline that DAWs expect. Additionally, AIFF is the native import format for many Mac-based studio workflows.
常见使用场景
- Importing AAC podcast episodes into Logic Pro for mastering and mixing
- Preparing AAC music tracks for DJ software that requires uncompressed input
- Creating AIFF reference files for audio quality comparison testing
- Loading compressed recordings into Pro Tools sessions for post-production
