Hi, please don't add normalize to the article. It's an RMS-normalizer, not an RG-scanner. -- Kjoon lee 03:01, 24 August 2006 (UTC)

I know that there is at least one hardware DAP, probably several, that support ReplayGain-tagged data. Notably the Rio_Karma. Mojo Tooth 23:52, 11 May 2007 (UTC)

The Sansa Clip/Clip+ flash DAP now both support ReplayGain with the newest firmware. Clip+ review: [2] also mentions that the Clip has upgraded its firmware to support Replay Gain. —Preceding unsigned comment added by 12.53.118.3 ( talk) 00:24, 1 September 2009 (UTC)
"Another benefit of Replay Gain scanning is that the peak information can also be used to prevent loud songs from clipping." ( http://en.wikipedia.org/wiki/Replay_Gain) contradicts "Audio volume leveling, prominently Replay Gain, is perhaps the most widely used solution. It should be noted, however, that this can only reduce the volume of loud music so that it is not proportionately louder than the listener's other music. It cannot restore dynamics or undo clipping."

Sure, one can multiply all samples by 2 or any other integer as long as they don't exceed the rails. But can one multiply all samples by 7/5 without introducing noise? -- Damian Yerrick ( talk | stalk) 01:05, 11 August 2008 (UTC)
I thought "directly modifying" meant changing the samples, which as far as I know adds noise, and saving under the same name. This is the "destructive" approach. -- Damian Yerrick ( talk | stalk) 01:05, 11 August 2008 (UTC)
To what precision does MP3 store its scalefactors? Can I scale all the scalefactors in an MP3 stream by 7/5 and then by 5/7 without introducing noise? And what other popular lossy codecs have values analogous to scalefactors? I'm guessing Vorbis "floor" curves are something like them. -- Damian Yerrick ( talk | stalk) 01:05, 11 August 2008 (UTC)

Since the article discusses PMPs/MP3 players, it would be nice to know about any players with ReplayGain that work on mobile devices. A.k.a. ( talk) 18:08, 15 January 2010 (UTC)
From the article: “the target loudness of most Replay Gain utilities is 89 dB”. When we’re dealing with actual sounds, 89 dB is an objective measure. But Replay Gain utilities deal with digital recordings. The same digital recording will be played back at different dB levels on different hardware (sometimes drastically different—think movie theater vs. headphones). So, what does this “89 dB” actually mean for digital recordings? To put it simply, in a PCM range of 0.0 (silence) to 1.0 (full volume), where does this “89 dB” fall? John lindgren ( talk) 03:01, 25 August 2010 (UTC)
:What I've gathered is that ReplayGain assumes 16-bit CD audio and references 0 dB to the noise floor and that makes 96 dB is full scale. 89 dB is 7 dB below full scale. A bit wacky. It is more common to use 0 dB as your full-scale reference (and -96 dB would be your noise floor for 16 bit audio) --

No consensus to move.

Replay Gain → ReplayGain – David Robinson, the original publisher of the proposal, has declared preference for the single-word name ReplayGain. See discussion at HydrogenAudio for verification. Kvng ( talk) 17:09, 12 July 2011 (UTC)
Hello fellow Wikipedians,
I have just added archive links to 2 external links on
ReplayGain. Please take a moment to review
my edit. If necessary, add {{
cbignore}}
after the link to keep me from modifying it. Alternatively, you can add {{
nobots|deny=InternetArchiveBot}}
to keep me off the page altogether. I made the following changes:
When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{
Sourcecheck}}
).
An editor has reviewed this edit and fixed any errors that were found.
Cheers.— cyberbot II Talk to my owner:Online 00:54, 21 March 2016 (UTC)

The section claims that ReplayGain’s target volume is 89 dB SPL, or −14 dBFS. This is not, and has never been, true.
The original ReplayGain specification defines the target as the loudness of a stereo pink noise signal played at −14 dBFS, or 89 dB SPL. ReplayGain 2.0 changes the loudness measurement algorithm to ITU BS.1770-3 and targets −18 LUFS, which is a value chosen to match the prior ‘pink noise at −14 dB’ target closely and keep compatibility ( source). Most ReplayGain scanners use ReplayGain 2.0.
The section also claims that EBU R128 recommends 23 dB of headroom, i.e. a normalisation to −23 dBFS. This is likewise untrue; the recommendation is −23 LUFS. 2003:F3:4F23:F100:B317:D894:5714:2BB ( talk) 16:42, 19 July 2023 (UTC)
Most ReplayGain scanners use ReplayGain 2.0.. Normalisation to −23 dBFS is 23 dB of headroom, by definition really. ~ Kvng ( talk) 14:40, 23 July 2023 (UTC)
