Why should I convert AAC to AIFF?

Converting AAC to AIFF is useful when you need uncompressed, sample-accurate audio for professional editing, archiving, or exchanging audio without further compression.

Will converting AAC to AIFF improve the audio quality?

No, the conversion will not restore lost audio data from AAC's lossy compression; it only preserves the current quality in an uncompressed format.

Are AIFF files larger than AAC files?

Yes, AIFF files store uncompressed audio, so they are significantly larger than the compressed AAC files.

Tips & Best Practices

Ensure your source AAC file uses a compatible profile for optimal conversion results
Use AIFF format when lossless, sample-accurate audio is required for editing or archiving
Remember that converting from lossy AAC to AIFF increases file size without restoring lost audio data
Consider tagging or adding metadata separately since raw AAC streams may lack this information

Limitations

Conversion does not recover audio data lost due to AAC's lossy compression
Resulting AIFF files are significantly larger due to uncompressed audio storage
Potential compatibility issues with AIFF's big-endian byte order on some platforms
AAC profile restrictions, licensing, and lack of metadata in raw AAC streams remain relevant after conversion

Key Terminology

AAC (Advanced Audio Coding): A lossy audio coding format optimized for streaming and digital music with profiles like AAC-LC and HE-AAC for efficient compression.
AIFF (Audio Interchange File Format): An audio format developed by Apple that stores uncompressed PCM audio, often used for professional recording and editing.
Lossy Compression: A data compression method that reduces file size by removing audio information that is less perceptible to human hearing.
PCM (Pulse-Code Modulation): A method of digitally representing uncompressed audio signals, preserving full audio fidelity.
