Ok I have been working non stop on my first cd and it sounds great when I play it on the home stereo.No background noise,absolutely perfect sound quality....but when I play it in the car all of the sudden(I dont know if im explaining the sound right) its almost like it cant handle the bass and sounds like the recording was recorded all in the red levels. I mean its not like terrible but for example when I am palm muting a fast riff it like farts out in the car and sounds like it was recorded in the red when every single track was well below the red. A friend told me that mastering would proble take care of it...As I said it sounds perfect on the Home stereo. Will a good mastering program proble take care of it? I also have a TC finalizer express rackmount would that work or are the computer programs for mastering alot better?
