These specifications based on the ITU-R BS 1770 accurately match the EBU R128 and fit perfectly within the tolerance range of ATSC A/85 or ARIB TR-B32. The chosen highest loudness value allows further normalization adjustments without affecting the audio quality (e.g., if you need to set precisely the loudness target at -24 or -27 LKFS).
- Integrated loudness: -23 LUFS (*)
- Average dynamic: ± 16 LU
- Short-term max.: ≤ -18 LUFS
- Momentary max.: ≤ -15 LUFS
- True peak max.: ≥ -12 dBTP and ≤ -6 dBTP
(*) One unit of LUFS is equal to 1 LKFS.
K14 audio files loudness (streaming)The integrated loudness target at -14 dB LKFS accurately matches the most recent YouTube volume normalization value and those from other popular streaming platforms. Therefore, any automatic normalization process will not impact the audio quality and prevent distortion or clipping. If necessary, you can also normalize your tracks for other lower values (e.g., if you need to set the target volume to -16 or -18 LKFS for a podcast).
- Integrated loudness = -14 LUFS
- Average dynamic = ±12.7 LU
- Short-term max.: N/A
- Momentary max.: ≤ -8 LUFS
- True peak max = ± 1.3 dBTP
