what will be the best sulution.. to remove those frames
in a automated manner. (directcut, mp3trim or some other..)

Sounds like a bit reservoir 

Try lowering gain in first frames (i think mp3trim can do this). And see whether it helps much.

Removing frames is not necessarily a good choice. The number of frames to remove will not be the same

Ciao..

yes.. the mp3trim did exactly as i wanted..
as this album is a vinyl rip.
there was also some hum.. that was edited out..
so now it`s perfect.

now a second question..
this is going to a audio cd..
what is recommended.. mp3gain the files..
then decode and burn..
or decode - wavegain and burn..

coz of HD space.. i used to mp3gain all files..
(exept tracks that needed editing..
those have been wavegained..)
but now.. when BAO can use WG. after decode..
i have used that..

is it some crucial diff. in those two..(exept the obvious..)
that i need to know..
 

some assistance...

Hello,

I may quote 2Bdecided (David):

Quote
[...] mp3gain does change the data in an mp3 file, but the change is perfectly reversible because it's a numerical subtraction, with no rounding loss. It can can be reversed simply by adding the same number that was subtracted.

However, in a wav file, changing the volume involves Dividing every sample by the same number. Division almost always increases the number of decimal (or binary!) places, and so introduces rounding errors with fixed point numbers, and is hence a lossy process. If you divide by a number, round the result to store it in a fixed point file, and then multiply by the same number, the rounding means that you do not get the exact same result back.
