[DOUBLE-POSTING (TOS #6)] From: R128GAIN: An EBU R128 compliant loudne

Quote from: pbelkner on
There are only two algorithms: (classical) ReplayGain and ITU BS.1770.


You're right.
I also watched this short clarification:
Florian Camerer (2012) ITU BS.1770-2 Gating Scheme, http://www.youtube.com/watch?v=Y-zhAEu5nVo

So could I now try to wrap-up by stating the following:

(1) LOUDNESS METERING
=================
(1.1) PROGRAMME LOUDNESS = single value to indicate integrated loudness for duration of the programme (track / album)

[blockquote]Two options:
(1.1.1) Classic Replaygain algorithm (2001).
(1.2.1) ITU BS. 1770 algorithm. Including gating function when signal drops below a certain point, specified as of revision ITU-R BS.1770-2 (03/2011). Latest: ITU-R BS.1770-3 (08/2012).[/blockquote]
(1.2) LOUDNESS RANGE
[blockquote](1.2.1) EBU-128 specified as difference between low and high percentiles of distribution of loudness as measured with ITU BS. 1770 algorithm including gating[/blockquote]

(2) LOUDNESS NORMALIZATION / LEVELING
=============================
Loudness leveling of programmes/music compliant to:
[blockquote](2.1) EBU-R128 norm, using -23 LUFS as target level.
(2.2) Classic ReplayGain 1.0 spec, reference -89 dBFS. Only applicable if (1.1.1) was used.
(2.3) ReplayGain 2.0 spec ("RG2"), mapping Loudness (L) metered with (1.2.1) onto dB's using empirical formula: RG2gain = -18 - L
(2.4) ATSC-A/85, using -24 LUFS[/blockquote]
