I suggest we discuss about possibility of creating ReplayGain2 specification that would replace the current ReplayGain.
ReplayGain2 would be playback compatible with the current ReplayGain (all current ReplayGain compatible players would work), but it should use ITU-R BS.1770/EBU R128 to calculate gain levels. Current ReplayGain algorithm is odd and difficult and not properly specified. It also does not work for multichannel audio. ITU-R BS.1770/EBU R128 would overcome these issues. |

This has been discussed. I believe there's actually good consensus on it. There are already tools supporting it.
Why don't you search this forum for ReplayGain and R128 and post some links and a summary of where we stand. I've created a ReplayGain 2.0 page on the wiki. It is currently a copy of the 1.0 specification. Feel free to start editing to make it 2.0. I'll help as time allows me. This post has been edited by Notat: Jul 23 2011, 17:37 |

So that is the way to go. I suggest someone will create an actual ReplayGain2 standard specification at wiki. This way all applications will follow the same specs, will be updated from ReplayGain1, and will be 100% compatible with each other.

If I may ask, how different are gain values between this ReplayGain2 algorithm and the original ReplayGain? Is it worth re-scanning one's collection with the new algorithm? Thanks!

I've been contacted by jaynyy and we've discussed moving this update forward. Jay is going to start by replacing the ReplayGain 1.0 loudness measurement with BS 1770-2. There are pointers to some of the other improvements we've discussed on the wiki talk page.
Further discussions of other improvements can happen here or on the talk page. Thanks Jay for stepping up to help make this happen. |
