please help...i am trying to find an effective way to reduce the hiss from my mixes without making them flat...can anyone offer some good tips? i use Cool Edit Pro for all recording and mixing...i record at the highest level possible so i don't have to boost too much during the mixing stage..the main problem is that i can't seem to figure out if there is a way to cut those unwanted hisses without dulling the entire track...any advice would be greatly appreciated..

You mean gain right? .. the eq on the mixer is perfectly flat, as in all the knobs are right in the middle?

Your hiss, is it the S word , or High end noise?

What's causing the hiss dude .. the mic?

You can experiment by applying a very steep and narrow EQ cut and various frequencies to figure out where the hiss 'lives'. Once you know here it lives you can hunt it down and kill it. :-)
 
It sounds to me like the hiss is being recorded with your initial tracks. This suggests a problem somewhere, either mics, room, enviroment, or electrical (I guess that would be a hum). Rather than figure out how to eliminate it in the mix, you should concentrate on finding out where it is coming from and eliminate the source.
 
i would have to say that it is due largely to vocals or any other time using the microphone..never occurs when i go directly into the board..
 
Room noise?

Sounds like it might be ambient room noise.

How have you tried to deaden your space?

It could be your mic cable .....or anything for that matter

I agree you should try to isolate the problem and repair it. In the mean time, the Sonic Foundry noise reduction plug in is a good way to remove noise without loosing content.

Give us something concrete to work with here, or if you prefer, we can continue to banter about with guessing games...........

What mic pre are you using? What mic?? What gain structure are you running at??? What levels are you setting on your pre?

Help us help you....!

- Audix Om6 microphone
- Fostex XR-5 4 track <----use this as my pre-amp for mic
- when recording, i push levels to about -3 to -6dB or as close to 0 as i can get.
- my room is approximately 16' X 25' X 10' (width-depth-height)
- it stays very quiet when i record with microphone.

can't think of what else to add. hope this helps
 
Here's the thing about ambient room noise. If a room is bright enough (lotsa reflective surfaces) it can generate standing sound waves all by itself.

The easiest way to see what I'm talking about is the seashell test.

Take a coffee mug and hold it up to your ear. That sound you hear in the mug is not an echo of the blood in your ears (although that myth pervades), but an amplification of the ambient noise in your room.

If there is no noise, then you have a pretty good dead space for mic recording. If not, then you could do worse than to baffle the room a bit.

I'm not familliar with that mic but neither that mic nor the fostex 4track come to mind when I think of a clean signal path.

Get an audio buddy and a decent condensor and your hiss should be much less. Using half decent equipment on a DAW there really is no reason to ever have objectionable hiss.

Hums and room noise are another issue.
