AAC Audio
audio/aacAAC (Advanced Audio Coding) is a lossy audio compression standard designed as the successor to MP3, offering better sound quality at equivalent bitrates. It is the default audio format for Apple devices, YouTube, and many streaming platforms. AAC supports sample rates from 8 to 96 kHz and up to 48 channels of audio.
Advantages
- Better audio quality than MP3 at the same bitrate
- Default format for iTunes, Apple Music, YouTube, and many streaming services
- Supports multi-channel audio up to 48 channels
Limitations
- Lossy compression permanently removes audio information
- Slightly less universal hardware support compared to MP3
- Patent-encumbered format with licensing requirements for encoders
Common Uses
- Apple ecosystem audio including iTunes and Apple Music
- YouTube and streaming platform audio encoding
- Mobile audio content and digital broadcasting
Target Format
AIFF Audio
audio/aiffAIFF (Audio Interchange File Format) is an uncompressed audio format developed by Apple, based on the IFF (Interchange File Format) structure. Like WAV, it stores raw PCM audio data at full quality, but uses big-endian byte ordering. AIFF is the standard uncompressed audio format in macOS and professional audio production on Apple platforms.
Advantages
- Completely lossless with full PCM audio quality
- Native support in macOS and all Apple audio software
- Supports embedded metadata including loop points for music production
Limitations
