What's the best way to re-write ReplayGain Metadata?

[Max Dread]

Hi

There are two scenarios where I am going to need to re-write ReplayGain...:

1. When individual tracks on an album have errors, the Album RG will then be wrong if those tracks with errors are re-ripped on their own and added to the album.

2. For some double albums (especially live ones), rather than having them as Disc 1/2, I am going to have them all as one album (and offset track numbers accordingly using the feature in CD Ripper). An overall Album RG will then need to be done for all the tracks form both discs.

I wondered if others in the same/similar boat would be willing to share their workflow when it comes to sorting this out? In case it's relevant, I am using the multi encoder to rip to FLAC and mp3 at the same time. I use Foobar for playback.

Many thanks

Max

To re-apply ReplayGain using dBpoweramp, run Batch Convert, select albums and run the ReplayGain DSP with the appropriate settings OR use alternative software that applies ReplayGain e.g. Foobar2000.

I'm not sure there's a best way of applying ReplayGain though, just different ways.

Thanks for the reply mville. A couple more questions if you (or anyone else) don't mind...:

1. Do I need to remove the existing RG before re-applying new values?

2. If I use Batch Convert, are totally new FLAC files written (IF I'm going from FLAC to FLAC for example). Or is JUST the new RG written when converting from and to the same format?

3. Does Foobar use EBU R128 -18LUFS? I read a thread saying it does, but just wantt o check that it has not recently changed....

Many thanks

Re: What's the best way to re-write ReplayGain Metadata?

1. No
2. Not if you convert to [ReplayGain] it is a utility codec
3. It uses EBU but a different level I think

Re: What's the best way to re-write ReplayGain Metadata?

1. Do I need to remove the existing RG before re-applying new values? 1. No

Well that's handy then. Presumably then DBPA/Foobar just ignores the existing RG data and replaces with the new calculations? Nice!

If I use Batch Convert, are totally new FLAC files written. Or is JUST the new RG written when converting from and to the same format?2. Not if you convert to [ReplayGain] it is a utility codec

OK, so what do I need to choose in the converter window? Do I have to have an encoder listed? I cannot see an option to choose "No encoder" and just have the DSP (RG).

Does Foobar use EBU R128 -18LUFS? 3. It uses EBU but a different level I think

If anyone here knows what level it uses, please let me know.


Many thanks to all.

You set the encoder to [ReplayGain], you have to install it from the utility section of Codec Central.

Gotcha! My apologies... I don't think I have the difference between codecs and DSPs clear in my mind. I was trying to use the DSP....

OK, so I have the RG Codec installed and have chosen it in MC. But I cannot see an option to change the LUFS Target Level. Is there one? If not, is it set to the default -23?

Cheers

Re: What's the best way to re-write ReplayGain Metadata?

It is default -23

[Max Dread]

Re: What's the best way to re-write ReplayGain Metadata?

It is default -23

And it cannot be changed?

If that is the case, is there a way to re-write RG to a -18LUFS Target Level using DBPA? Or do I need to look elsewhere?

Yes and I don't think it can be changed.

There is- setting for the DSP that will allow you to change to -18. At least there is when RG DSP used in ripping. Foobar2000 is set to -18. Personally, when I want to change RG values in situations like yours, I just do it with foobar2000. It overwrites old values.

Do you not see this?

Sure, I've seen the setting in the DSP but it is missing in the codec.... So I think I'll follow the same route as yours and use Foobar to re-calc when needed. Especially seeing as:

Does Foobar use EBU R128 -18LUFS? Yes and I don't think it can be changed.

which is exactly as I want it and what I use in DBPA.

So presumably there are no differences in how Foobar and DBPA (set to -18) calculate replaygain?

Thanks guys.

Do you not see this?

No I don't. I must have an old version perhaps...? I just downloaded it directly from Codec Central.... In the DBPA Configuration it is listed as Release 2.
