Make it louder?

Post by psimon » Mon Jun 20, 2011 8:51 am

Hi there
When I play songs I've recorded from vinyl on my iPod, they are always quieter than the tunes I've bought as MP3s direct to iTunes. Is there a way I can boost my Audacity-recorded files before I encrypt to MP3?
I've been experimenting with the 'Normalisation' function. But I'm not a recording engineer or mathematician, so the nature of +ve/-ve dBs has always foxed me a bit, I must confess...

The MP3s you've obtained have probably been remastered to make them sound louder. The Normalize function in Audacity will maximize the amplitude of the song according to the maxiumum peak. This does not necessarily translate into "louder". Since you are recording from vinyl you should make sure you do click removal before normalizing.

You could always try using the iTunes/iPod function which levels out the amplitude across all the "songs" in your library.
