Frequently asked questions
What does EBU R 128 measure?
EBU R 128-2023 recommends a programme target of −23 LUFS. This checker uses ±0.2 LU for programme QC or ±1 LU for live programmes and a −1 dBTP production true-peak ceiling. Loudness range describes dynamics rather than a universal pass/fail limit.
Does this certify my video for broadcast?
No. This checks integrated loudness and true peak on one selected audio track. Broadcasters may require additional channel, metadata, short-form and delivery checks. LRA is not recommended for programmes shorter than one minute. Consult the destination delivery specification.
Are my audio files uploaded?
No. FFmpeg runs locally in your browser after a one-time engine download. Choose an audio or video file under 300 MB, select the audio track, and download a JSON measurement report without an account.
