Learn about the source and target file formats to understand what happens during conversion.
Source 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
- Very large file sizes comparable to WAV
- Less universal than WAV on non-Apple platforms
- Not suitable for portable use or streaming due to file size
Common Uses
- Professional audio production on macOS
- Apple ecosystem audio recording and editing
- Music production sample libraries and loop files
Target Format
M4A Audio
audio/mp4M4A is an audio-only MPEG-4 container file that typically contains either AAC or Apple Lossless (ALAC) encoded audio. It was popularized by Apple as the default format for music purchased from the iTunes Store and ripped from CDs in iTunes. M4A files support rich metadata including album art, lyrics, and chapter markers.
Advantages
- Better audio quality than MP3 when using AAC encoding
- Supports both lossy (AAC) and lossless (ALAC) audio codecs
- Rich metadata support including album art, lyrics, and chapters
Limitations
- Slightly less universal compatibility than MP3 on older devices
- Can be confusing due to containing different codecs (AAC vs ALAC)
- Some older car stereos and portable players lack M4A support
Common Uses
- iTunes and Apple Music audio library storage
- Audiobooks and podcasts with chapter markers
- High-quality music distribution on Apple platforms
