Lame 3.96 - User def. tag field?

In my mp3s I see an ID3v1 field

"ENCODERSETTINGS"
with the value
"LAME v3.96"

Is it possible to add a user definable ID3 header field? I wish I could add a field like:

"Settings" // "-V 5 -b 112 --athaa-sensitivity 1 --vbr-mtrh"

There's no ENCODERSETTINGS field defined in ID3v1.
ID3v1 has no support for custom fields, while ID3v2 and APEv2 do.

The LAME header as such a field, indicating the lame version used to create the MP3:

I always write the used settings in short form in the comment field presents in ID3v1 tags. that's of course only a good idea if you actually use ID3 tags, and don't have any other use for the comment field...

Wrong.

ID3v2 has the following standard fields:

TENC = Encoded by
TSSE = Software/Hardware and settings used for encoding

and of course User defined fields
TXXX  = User defined text information frame

Quote
This frame is intended for one-string text information concerning the audiofile in a similar way to the other "T"-frames. The frame body consists of a description of the string, represented as a terminated string, followed by the actual string. There may be more than one "TXXX" frame in each tag, but only one with the same description.


<Header for 'User defined text information frame', ID: "TXXX"> 
Text encoding $xx
Description <text string according to encoding> $00 (00)
Value <text string according to encoding>

You can use the TXXX frame of ID3v2 to create a ENCODERSETTINGS field (so does foo_id3v2 and my tagger).

I didn't think about TXXX fields. Sorry.

TSSE = Software/Hardware and settings used for encoding
But as far as I can see theres no possibility setting such tags with EAC/lame...

foo_id3v2 maps TSSE to %ENCODERSETTINGS% and TENC to %ENCODEDBY%.
Mystery solved.
I'm pretty sure that EAC sets at least TENC when using its ID3v2 tagging.

So AFAICS Lame 3.96 is doing wrong, as it sets TSSE to "Lame 3.96"?

What settings are you using in EAC?
Are you using lame_enc.dll by any chance?

I'm using lame.exe.  I have never used lame_enc.dll.

for my car audio:

-V 5 -b 112 --athaa-sensitivity 1 --vbr-mtrh --id3v1-only --ignore-tag-errors --tc "V5 b112 vbr-mtrh athaa-sens1" --tt "%t" --ta "%a" --tl "%g" --tn "%n" --ty "%y" --tg "%m" %s %d

idv1 cause my car player does only support v1.

And EAC's ID3 tagging is set disabled?

Well, depends on how you see it. Encoded by can also be interpreted by the person who encoded the file, not the software which did it.
The ID3v2 committee define TSSE as "Software/Hardware and settings used for encoding", whereas "and settings used for encoding" can be ommited. In that case, LAME is allowed to write "LAME 3.96" inside a TSSE frame, as it is the "Software used for encoding".

Yes of course.

Now, I'm puzzled... Guess a LAME dev has to come in and answer. I'd be really worried if LAME added ID3v2 tags when forcing it not to.

The above command line DOES NOT WRITE ID3v2 tags.
He should check again.

LAME works fine period.
Either check EAC or the validity of his statements.

Ah, this is why you're asking!!! No need for confusion! When I mentioned "So AFAICS Lame 3.96 is doing wrong, as it sets TSSE to 'Lame 3.96'?" I wasn't refering to the command line I mentioned! No need for a lame dev.

No, the question is, if Lame does IDv2, why is TSSE set to "lame v3.96"? Lame should set TENC to "lame v3.96"..

Sorry for the confusion

Lame devs should add more info IMHO to the Id3v2 frame including all the command line switches.
