Music Scanner to set Playback levels


recently i've been using VLC to run play-lists . as we all know VLC is a very good player for most anything

one of the interesting things about VLC is the "Information" request option. This will show Replay Gain information --- if that data is present

as we all know recordings tend to be at different levels and you may want to keep that gain control handy

some of my .flac files have this set while on others it is missing ...

so,-- the question -- do we know of a program that can scan .flac files and set the replay gain ?

there's a perl module that can do that:
Code:
aur/perl-music-tag-flac 0.4101-1 (3)
Plugin module for Music::Tag to get information from flac headers
but i'm sure there's other ways.
how about:
Code:
community/mediainfo 0.7.74-1
supplies technical and tag information about a video or audio file

It probably does not include movies as you would have to parse the entire file before playback. I just checked mediainfo, which has a huge list of parameters. As far as I can tell there is no place in any of the containers it can handle where you can store metadata information on normalization. I could be wrong, but I don't see it being possible at the present time.

With my method I recode the entire audio track to the same levels you would achieve through normalization. I have successfully achieved this with audio from wav to flac, to vorbis, to mp3 to god only knows what. This, of course, applies to the audio portion of movies from avi, mpg, mpeg, flv, mp4, and who knows what else.

As to flac itself, it too does not store normalization metadata, which limits your choices to recode it to some other (probably lossy) format with a considerable drop in audio quality but has normalization, put up with it as is, or recode the file to the same format but with the gain applied directly to it. That way if you ever wish to recode it, there will be no need to ever consider replay gain as it is no longer an issue.

Here is a link to my post.
