Hi from Italy !

If I need to lower the volume of a song that then I need to encode, is it better attenuate the volume BEFORE encoding using Cool Edit or is good enough use the "--scale n" option DURING encoding ?

Example:
--alt-preset standard --scale 0.89 is GOOD THE SAME as --alt-preset standard applied on a song pre-normalized at 0.89 ?

I mean ONLY about QUALITY !

Thanks !

I would seriously doubt that there's any real difference. The LAME --scale option also applies the scaling to the samples before encoding.

PLEASE : move my question to his right place.


( I think MP3 general)

Thanks

What about just using mp3gain so that the changes are not permanant?

I know this, but my question is different and precise: I need encode a lower volume.

Thank You

The rusults would be quite similar. The only difference is that Lame is doing the scaling on 32bits floats.
