Replay Gain in next nightly/firmware 22

[vidurapparao]

Latest svn and the next nightly build (along with Squeezebox2 firmware
22) implements volume normalization/Replay Gain for various audio and
tag formats - ogg, FLAC, MP3Gain (APETAGEX), AACGain, RVAD (MP3 via
iTunes) and RVA2.

There is now a Replay Gain setting under the Player Settings > Audio
section of the web interface. This setting can take the following values:
1) Disable Replay Gain
2) Use Track Gain (if present) - uses only track gain information.
3) Use Album Gain (if present) - uses only album gain information.
4) "Smart" gain selection - uses ideas and code from James Sutula's
Dynamic Transition Updater/Smart Gain plugin to dynamically choose
between track and album gain. The idea is that album gain is used if
successive tracks are from the same album and in track order, track gain
is used otherwise.

The last is the default value of the setting. Please give this a try,
post feedback and file bugs if you see any. I'm open to alternate ideas
for the setting choices and default.

Thanks to Dan Sully for tag parsing/database work and James Sutula for
his plugin.

Is ReplayGain being applied on the player itself or is the file being transcoded (say, flac->flac) on the server with the ReplayGain info applied?

It's being applied on the player. As I mentioned, we now support
multiple ReplayGain tag formats, so this is not just FLAC specific.

Nice!!! Well done!

It's now time for me to start playing with the nightlies, I guess. . .

I have not tried it yet, but I sure do appreciate this work. To everyone who had a hand in implementing this: Thank you!!

One other issue that was fixed in conjunction with replaygain was
that the volume curve for Squeezebox2 was made smoother, with more
resolution in the low end. The maximum output level is the same.

This means that after the update you may find that your loudness is
lower for your current volume setting. Crank it up.

Feedback welcome on this new curve.

FYI - RVAD isn't working quite yet. I've just checked in a change to disable
it. However, if you have files with those tags, you'll want to wipe & rescan
your database.

Sorry about the trouble.

Is the plan to put options for replaygain into the SqueezeBox's menus? It would be much easier to be able to easily select these settings from the arm chair. Then again, if it was possible to only have it turn on when the playlist is shuffled, I would probably never need to touch the settings. Is this a possibility, or is there a blocker somewhere?

I'm currently adding replaygain tags to all my flac files so will hopefully be able to some testing of this great new feature over the weekend. Thanks for all the work in adding it.

Can anybody clarify where the volume adjustment is done? If I am running digital outs to an external DAC, with the SB2 player option set to fix the digital output volume, then will Replay Gain still do what it is supposed to?

(In case it matters, all files are flac, streamed as flac.)
