LUFS
LUFS (Loudness Units Full Scale) is a standard way to measure how loud audio sounds to human ears. In audiobook production, it's like a volume measurement tool that helps ensure all audio books have consistent loudness levels, so listeners don't need to keep adjusting their volume. Think of it as a quality control tool that helps audio professionals deliver properly balanced sound that meets industry standards, similar to how food products must meet standard measurement requirements. When you see this term in resumes, it indicates that the person understands how to deliver audio at the correct volume levels for platforms like Audible or other audiobook distributors.
