Pre-gain for non-replaygain tracks.

(1/3) > >>

nwimpney:
This subject has been mentioned before in other threads, but I think it deserves its own.

It would be good to have an option that sets a pre-amp value for tracks that don't have replay gain tags.

This way, when you play a track that isn't tagged, it will be reduced to a volume similar to the reference level (obviously only a guess, depending what you have it set to) instead of playing it at full volume.

Currently, the suggested behaviour is to set a pre-gain to compensate for your estimated average replaygain values, but that seems pretty backwards.

IIRC we decided at some point years ago that we wanted this, and have just been waiting for someone to add it.

Llorean:
Isn't this the Equalizer Pre-Amp? His stated purpose was to decrease, and that's already possibly in Rockbox independently of the presence of replaygain tags.

Edit: I may have misunderstood - do you mean for non-replaygained track within a mixed collection? It seems like you shouldn't apply replaygain settings to non-replaygain tracks, but again you could use pre-amp from the equalizer to increase the volume of your tracks in general, and pre-cut in replaygain itself to adjust only those tracks with tags allowing you to adjustthe wo types of tracks separately.

Basically, right now we have a precut for replaygain tracks, and a global one in the EQ, but no way to apply a separate one to tracks that are missing replaygain info.   

Llorean:
Isn't applying one to all tracks with Replaygain info the opposite amount and then globally compensating mathematically exactly the same?

Subtract 6 from non scanned tracks is the same as adding six to scanned ones and subtracting six globally. Why do we need even more settings?

Why would you prefer to adjust nonscanned tracks only rather than scanned track only? You could raise scanned by 6 or lower nonscanned by six and either way you get the same difference, then just adjust the global level or even just the volume.
