Applying ReplayGain to existing FLACs Options

[rbz]

Hi,

my first post here after a long time of lurking.

I ripped a lot of my CDs to FLAC, one file per track. Encoding was done either with EAC + FLAC or with FLAC frontend. I did not use ReplayGain (RG) on that occasion, but want to add RG now. Maybe I missed something obvious, but I can't find a way to add RG to existing FLAC files at all.

N.B.: The reason for not using RG in the first encoding was that I couldn't find a way to adjust the gain volume level from the standard 89 dB to, say, 92 dB SPL. FLAC frontend only has a switch to apply RG without additional adjustments (unlike e.g. WaveGain, which I used on another occasion). From what I read about FLAC's command line switches, it doesn't have an option for additional gain. But due to the miserable state of portable DAPs' output volumes (esp. in Europe), I need to adjust the values for louder output.

How could I accomplish this?

TIA

P.S.: I already thought about transcoding FLAC -> FLAC, but that way, I would lose my tags/comments/cover art into which I put a lot of work, wouldn't I? And I still couldn't alter the SPL.
