Replay Gain target value updated by its creator!
« on: November 25, 2003, 10:57:57 am »
David Robinson, the creator or "Replay Gain" has made a statement at another message board about the official target reference level. See the whole thread here:

http://www.hydrogenaudio.org/index.php?showtopic=15445&

Here is the message for developers:

Quote
Developers:

Almost everyone is using a reference level of 89dB, rather than the 83dB in the original ReplayGain proposal. Unless there are any objections, I'll change the official reference level to 89dB.

JRiver crew, will you be making the change?

I hope so!

..and because there has just been some changes in audio analysis, now it would be a good time to do it

MC needn't make any change ... simply have the replay gain play it back +6db ... voila! 89db

And voila, twice the amount of noise added!

I imagine if the sound card's DAC and preamp contributes a bit of noise, then turning up the volume does amplify this additional noise.  The question is ... is it twice the noise, or negligible?  I don't know what you're using, ... but it is negligible, insignificant, nada for my Revo's analog outs.  I would also believe that it's absolutely nada, if the S/PDIF output is employed(?)

It is exactly the same as adding 6 more dB as an adjustment.  No extra noise is introduced because of this. (internally everything is 32-bit and either way it's just one volume adjustment if you adjust replay gain or not)

The only problem with us changing is that files we've tagged in the past use an 83 dB reference.  Since it doesn't really bring anything new to the table, we're not sure it's worth the troubles.

I've been using MP3Gain for all my MP3 replaygain. Any advantage to using MC's? Does it do album analysis yet?

MC's RG implementation is an island, where MP3Gain's tag based (as opposed to actually altering the data...it will do either) RG is supported by the more advanced players (except MC). Album based RG is not supported in MC...yet.
