What is AAC?

AAC (Advanced Audio Codec) is a modern lossy audio format that provides better sound quality than MP3 at the same bitrate.

What is AIFF?

Audio Interchange File Format (AIFF) is Apple's uncompressed audio format, offering CD-quality sound for professional audio production.

When Should You Use AAC vs AIFF?

AAC vs AIFF: Key Differences

• •AAC and AIFF diverge on compression: lossy compression for the source, lossless compression for the target.
• •Moving from AAC (lossless) to AIFF (lossless) means the output file will be larger — but every bit of the original is preserved.
• •Alpha channel support: AIFF lacks transparency support.
• •AAC files are typically Slightly smaller than MP3 at equivalent quality while AIFF files range 10MB per minute at CD quality
• •AAC is optimized for streaming, mobile audio, youtube while AIFF is designed for professional audio production, music recording — choose based on your specific workflow needs
