FAQ

Common questions about AAC

What is AAC best used for?

AAC is best for mobile playback, streaming, compact listening files, and modern lossy audio delivery.

Is AAC better than MP3?

AAC is often more efficient at similar bitrates, but MP3 is still the more universally recognized compatibility choice in many workflows.

Can converting AAC to WAV restore lost audio detail?

No. Converting AAC to WAV can help with editing compatibility, but it cannot recover detail removed by lossy compression.
