Replaygain tags missing

[dph]

I'm trying to use the Batch Converter to apply both album and track ReplayGain to existing MP3 files (that were not ripped using dBpoweramp). The Converter runs with no errors. When I check for the replaygain tags, I find most them, but they're missing from MP3s in a few folders. I've tried running the Batch Converter on just one folder or just one file at a time with no success. No errors, but no visible ReplayGain tags.

I've tried checking for the ReplayGain tags using:
* Foobar2000
* Right-clicking on an MP3 and selecting "Edit ID-Tag"
* MP3Tag (with columns set to display "replay_album_gain" and "replay_track_gain")

Here are the audio properties of one MP3 that doesn't seem to accept the ReplayGain tags:
=============
Artist Carlos Santana
Title Blues for Salvador
Album Blues for Salavador
Track 9
Disc
Genre Blues

Audio Quality High (Lossy)
Contains ID Tag [ID3v2 (ANSI) & ID3v1.1]
Channel Mapping Left, Right
File 09 Blues For Salvador

=============

Do I need to somehow "repair" or change ID Tag settings?

Software versions:
dBpoweramp Reference release 13.3
ReplayGain release 2

Thanks...

Re: Replaygain tags missing

I have a similar problem. I am trying to apply replay gain to some .m4a apple lossless files. I have tried replay gain, replay gain (applied) and volume normalize, but none of these seem to have any effect and make no modification to the ID tags, though my goal is to actuaslly modify the files, not just the ID tags.

Can .m4a apple lossless files be adjusted for replay gain? If so, how is it done.

I have dbpoweramp 13.3 reference and most recent dsp effects (release 5) and replay gain codec (release 2).

Re: Replaygain tags missing

jfkaess - you need to use 'Volume Normalize' and select the replaygain option.

OP: Which 'encoder' or DSP effects are you using?

Re: Replaygain tags missing

Unfortunately, I don't know what was used to encode the problem MP3s.

FWIW: I tried using foobar2000 to apply ReplayGain on the affected MP3s. The ReplayGain tags now show up under foobar2000 and MP3Tag, but not in any other windows ("Audio Properties", "ID-Tag", "Edit ID-Tag").

Weird.

Re: Replaygain tags missing

foobar writes id3v2.4 tags which dBpoweramp R13 would not read or write.

Re: Replaygain tags missing

That leaves me with two questions:

1. Which ID Tag format does dBpoweramp R13 use to write ReplayGain tags?

2. Do you have any theories why dBpoweramp is unable to write ReplayGain tags to some MP3s?

Thanks for helping me narrow this down.

Followup:

It appears that dbPoweramp writes id3v2.3 tags by default. I've kept multiple copies of the "problem" MP3s, which allows me to fall back and experiment. Here's what I've found, according to the "Audio Properties" tab:

* As mentioned in my initial post, the original tags showed as [ID3v2 (ANSI) & ID3v1.1]

* After applying dbPoweramp's ReplayGain, the tag remained [ID3v2 (ANSI) & ID3v1.1]

* After running foobar2000's ReplayGain, the tag showed as [ID3v1.1] only.

I tried converting one of the "problem" MP3s to id3v2.3 using dBpoweramp's ID Tag Update Utility following the Help instructions, but it simply removed all tag info (!).

Is there a way to manipulate these "problem" MP3s so that dBpoweramp can write ReplayGain tags to them or am I going at this all wrong? Can I send you one to troubleshoot?

Re: Replaygain tags missing

Foobar can be set to write v2.3 there is a compatibility option.

Re: Replaygain tags missing

I sure hope I'm not belaboring, but I'm still in the dark about my original question: Why would the Batch Converter be unable to write ReplayGain tags to some MP3 files?

If the Batch Converter is actually writing the ReplayGain tags, shouldn't they show up when I right-click on the MP3 and select dBPoweramp's "Audio Properties" tab?

Ultimately, is there a fix/workaround that would allow the Batch Converter to write the ReplayGain tags to the stubborn MP3s?

Re: Replaygain tags missing

If a file has a id3v2.4 tag, then dBpoweramp cannot write a v2.3 tag to it.

Re: Replaygain tags missing

Just letting everyone know that I resolved my issue by first running the "ID Tag Update" utility codec on the 'problem' MP3s, then running "ReplayGain."

I'm guessing that I could have run both utilities at once, but I didn't try that.

Thanks...
