digital amp?

[nuss75]

I have a lot of recordings with low volume and im constantly around 0db without anny bg-noice.
Now i wonder if ther is a plugin or a setting i can use to boost my volume in the file wihout editing it in a program. Like the preamp in winamp. I think the program doesnt amplify the signal itself but just alter it digitally so the whole soundwave is transposed up. I know if i eq everything to max i can get it ok but it is a hazzle.

an other question does anybody know a easy fast program that alters the wolume of a file whitout making it a wav file inbetween?

Google "Replaygain", then see the section on it in the Rockbox manual.

[nuss75]

yes that anser my second question about a a external program that can alter the files.
but what about the preamp?
does such thing exist?

[GodEater]

Have you read the manual at all ?

[nuss75]

yes i have. and as i recall using replaygain, a external program to modify the files, is the onely way i have seen. perhaps i missed someting and that is why i asked about a plugin or similar that can alter the volume without me having to  hook myself up to a computer inbetwene.... like winamp can without a replaygain modification inbetwene.
so do u have anny suggestion? If u have a suggestion that is not about an external program and hooking up to a computer  please post a link to it so i can find it becouse so far i just found replaygain...

From the Manual's description of ReplayGain:

Pre-amp.
    This allows you to adjust the volume when replaygain is applied. Replaygain often lowers the volume, sometimes quite much, so here you can compensate for that. Please note that a (large) positive pre-amp setting can cause clipping, unless prevent clipping is enabled. The pre-amp can be set to any decibel (dB) value between -12dB and +12dB, in increments of 0.1dB.

yea im going to use that option right now...
Im currently analysing my files with mp3gain and i can tell u it takes a loooong  time i was hoping to just be able to boost the range of the volume controle like in winamp where u dont have to analyse everything it takes like over an houer for my 30 files. I think that is quite much.
And for all my files like 40 gb it's going to take at least a week!
This solution is to timconsuming. thats why i asked for a simpler one.
From what i understand u have to analyze the files in order to aply this replaygain "preamp" its like a kids failsafe... u are not allowed to boost your volumen if u havnt chekt at what level it is first. it might distort... as i wouldnt notice... I think it is better to allow people to transpose the volume as they plese not onely if they have analysed the files first.
so i think a lot of people would appriciate this feture if it was possible.

mp3gain actually physically changes the gain in the mp3 file - it doesn't write ReplayGain information to the file, so you still won't be able to use ReplyGain once it's done.

First, I am going to insist that you proofread your posts and use real words instead of textspeak like "u."  Our posting guidelines require this, and they are strictly enforced.

Second, I believe that the Replaygain pre-amp setting will affect the volume of all files, regardless of whether you have scanned them on the computer and added Replaygain tags.  (I can't check this at the moment, because all of the files on my player have Replaygain tags, but perhaps someone else could confirm.)  Of course, you need to have Replaygain enabled in the Settings --> Playback --> Replaygain menu for this to work.

You can also achieve the same thing by using the "pre-cut" setting in the equalizer.

I can't make any sense of your comment about clipping.  Perhaps you could rephrase it to make it more clear.

[Llorean]

Actually, the replaygain pre-cut won't affect all files. It's designed for, for example, putting your replaygain files at a level similar to your non-replaygained files by adjusting them without moving any that lack tags.

The precut for the equalizer on the other hand affects everything, but I can't recall if it allows positive values.

[Febs]

The pre-cut allows only negative values.
