each time I record a new track to an existing project the humming noise of the PC increases.
If I start to add tracks, or copy , or add a lead instrument, when I play back the session, the hummig noise on the count-in is increase. ( gets louder)

Heres my setup
Beringer 802a
Cakewalk GTP
Audigy sc
compac Pc

How are you set-up for that recording project? Mics, keys, line-in, DI box? Are you getting a "bubbly" sort of sound that's audible whenever you move the mouse or if the hard drive writes? Or are you getting a hissing kind of noise, like an over-driven pre-amp, or a buzz, like an open ground? Or, are you getting a crackling & popping kind of noise? Also, are you monitoring thru headphones when you add your additional track(s), or are you going thru loudspeakers of some sort?

Be sure you've got any mic levels "hot" with the gain on the pre-amps of your mixer (refer to your owner's manual), set the levels in relation to each other with the Level pots, get as "hot" coming out the "mains" (or whatever "send" you use) as you can (without "overloading") to go into your soundcard's "Line In" jack, and set your levels in the software mixer to where you do NOT go over 0dB AT ALL. Then, of course, there's a mixer in GTP, also!

yeah it sounds like you are recording to quietly, and then boosting the tracks after you record them....

Im leanning towards what daddy has requested or informed me about recording to quietly, I use my head phones to add other tracks while i play and record. I notice that the light indicators on my berhinger mixer hardly move when i play into it, however, the levels on the track in cakewalk are at or about -12 to -6 and seems to record ok at that level. I also have set the gains to a hot level then pulled back just a lil, the same with the input level. the output level is at or about 3 or 4 on the scale of 10. any ideas, is it the soundcard picking up noice interally from the hd?
Would i set the output level higher then set the gains n levels, which gives me a fuzzy recording?

ick, fuzzy bad!! ok there's alotta different "audigy" soundcards...so i'm gonna assume that your are using the line inputs and using it to convert your audio to digital.

heheh this is another 'gain staging' post...

ok use the MAIN OUT of your mixer to go to the LINE IN of the soundcard, you're gonna need a proper connector cable to do this, so look at what needs what and buy accordingly. stay away from those RCA jacks, they run at lower levels.

turn all preamps (trim, gain) all the way down, and set your mixer to unity gain...all volumes, eqs and faders to 0DB (not all the way down)....pull down any channel faders you are not using and use ONLY the preamp's gain knob to set your levels.

that will yeald less noize in your recordings.
