Common Questions
What is a good LUFS level?
A good LUFS (Loudness Units Full Scale) level largely depends on the medium through which the audio is being delivered. For instance, streaming platforms such as Spotify, Apple Music, and YouTube recommend an integrated LUFS level of around -14 to -16 LUFS for optimal sound quality and loudness normalization. Broadcast standards might differ, with the European Broadcasting Union (EBU) usually recommending -23 LUFS for television broadcasts as per the EBU R128 standard. It’s important for audio producers to target the LUFS level that matches the target platform to ensure their content is heard as intended.What is LUFS in dB?
LUFS (Loudness Units Full Scale) is measured in decibels (dB), similar to other audio measurements. It is a standardized unit designed to accurately measure the perceived loudness of audio material. Unlike simple peak or RMS measurements, LUFS provides a more comprehensive representation of loudness by incorporating an algorithm that models human hearing sensitivity to different frequencies and loudness perception. LUFS values typically integrate measurement over the entire duration of a track or segment, providing a clear picture of its average loudness level.What is the normal LUFS level?
The 'normal' LUFS level can vary depending on the context of where the audio will be played. However, for most streaming services like Spotify, Apple Music, and YouTube, the recommended LUFS level is about -14 to -16 LUFS for the best balance between loudness and dynamics. This level makes sure that the volume is normalized across different tracks, giving users a more consistent listening experience. For broadcasting, a common standard is the EBU R128, recommending a broadcast LUFS level of -23 for television in Europe, ensuring compliance and uniformity in broadcast audio levels.Is 10 LUFS loud enough?
A LUFS level of 10 is considered quite loud and is generally much higher than the average loudness levels recommended for most streaming platforms and broadcasting standards. Audio at 10 LUFS could lead to listener fatigue due to its high loudness, and it might also suffer from dynamic range compression, which can affect the overall audio quality. Furthermore, streaming services typically normalize louder tracks to their standard levels (around -14 to -16 LUFS), so mastering a track at 10 LUFS can result in unnecessary loss of dynamics without achieving greater perceptual loudness for the listener.Implementing LUFS in Your Workflow
