View Full Version : Using FLAC to replaygain MP3s

Is it possible, with some specific setting for the slimserver-convert.conf
file, to convert MP3s to FLAC, passing the replaygain tag to FLAC, in
order to then decode FLAC to WAV with the
apply-replaygain-which-is-not-lossless function activated?

Currently I can use replaygained files in FLAC format, but for MP3s I
can't find a way to use them on Squeezebox1.

Is Squeezebox2 better in this regard?

Also, is there any plan to bring FLAC decoding to Squeezebox1 or does
Slimdevices intend to reserve it as an exclusive feature for the new player?

Cheers,

Andrea

Take a look at http://mp3gain.sf.net which will make replaygain-like adjustments
to your mp3 files that will work with squeezebox. The process is
reversible.

It doesn't appear like this is going to happen for SB1.

I second that.
mp3gain is what I use with all my mp3's.
It's great because I don't have to have my iPod adjust volume levels,
they are already adjusted - and that saves battery.

For an album - get all the songs in the same directory and just run

mp3gain -a -k *.mp3
That will analyze of them and apply the same gain to each song in the album.

There also is a port to aac called aacgain - I saw it talked about on
hydrogen audio but have not tried it.
