Tool usage guide
The Audio LUFS Meter measures the loudness of audio files using the EBU R128 standard. It calculates integrated, short-term, and momentary LUFS values to help ensure broadcast and streaming compliance.
Background
A broadcast engineer is finalizing audio for a TV commercial to air on national television.
Problem
The audio must meet EBU R128 loudness standards to avoid broadcast violations.
How to use
Upload the commercial's audio file to the Audio LUFS Meter.
Outcome
The tool outputs integrated LUFS values, allowing the engineer to verify compliance and make adjustments if needed.
Background
A podcast producer notices that episodes have inconsistent loudness, causing listener complaints.
Problem
Episodes vary in loudness, leading to a poor listening experience on streaming platforms.
How to use
Measure each episode's audio file using the LUFS Meter to get integrated LUFS readings.
Outcome
Based on the results, the producer normalizes audio levels to a target LUFS, such as -16 LUFS, for consistent playback.
LUFS stands for Loudness Units Full Scale, a standard for measuring audio loudness.
The tool supports common audio formats like MP3, WAV, AAC, and others via the audio/* file type.
LUFS measures perceived loudness over time, while dB often measures peak or RMS levels.
Currently, the tool processes one audio file at a time.
Integrated LUFS is the overall loudness, short-term is over 3 seconds, and momentary is over 400 milliseconds.
