Hello,

with all the extras fb2k offers already, there is one thing I really miss regulary.

I mp3gain my tracks after encoding (for later hardware device use, or other players than fb), then I scan them again in foobar for it's better precision (+- 0.75 dB)

Now what would be really cool is a plugin that would save me the external mp3gain step, by reading the album or track gain form the database/fb2k tag, apply the according mp3gain to the file (rounded to 1.5 dB step), and then alter the tags respctively.

For example: fb2k calculates an album gain of -8.12 dB. Then the plugin would apply mp3gain of -7.5 physically to the file, and set the album RG tag of the files to -0.62. The track gains would get a boost of +7.5 then also of course. I am not sure how hard it is to calculate the new peak values during that operation thogh, without re-scanning.

Thanks for your opinions

MP3gain (at least the frontend) adds the usual Musepack-style tags that foobar reads. No need to scan again in foobar.

How about (after Foobar scanning), just running a recursive (Case's Sweep.exe could help) batchfile for the MP3Gain CLI?

sweep.exe mp3gain.exe /a /c /p *.mp3

Or somesuch.

This should (using the already Foobar-calculated values) physically albumgain your mp3's and also modify the AP2-values accordingly.

What I'm personally looking for is a command for the MP3Gain CLI to calculate gains without physically altering the files, but only add the values as tags.
