Excellent tut there JKyle thank you.
Edit
@ JKyle
I have tried that twice now mate and there is no improvement in the sound! will tell you what I did
I did the 1st one like you said and clicked normalize then converted which made no difference in the audio, I did this again by unticking normalize and nothing happened.
Though what I have been doing with other files is this
When I add the command line into the custom it boost the sound without that command it does nothing. Though I have tried that command when I try to do a qaac conversion and it comes up with that error I put up earlier.
