Strong Noise whe recording with AA 1.5

[jorgepe]

I need your help in order to fix the problem I have with Adobe Audition 1.5 as follows :

When I try to record from microphone or CD, the recording has a strong noise. In order to analize what it could happen, I unplugged the microphone and the speakers, with the same results. It seems to be like a permanent background noise.

In other way, I have no problems when record from a microphone with Nero and/or with the Sound Record aplication included in Win XP.

The sound card I have installed is a Sound Blaster Live Creative 5.1.

I suppose may be it is a problem of configuration of Adobe Audition.

I would very much appreciate if you can help me to fix this problem.

Thank you very much in advance for your attention

The best for you.

I am not an expert. The only thing I can think of is maybe you need to mute either your microphone input or line in input on your computer soundcard settings IN OTHER WORDS mute the one that you are not using. Hope this makes sense and helps.

You might also check to see if the soundcard is firmly seated in the PCI slot-it may have somehow worked loose.
It sounds kind of like a ground problem is possible as well.
You may try uninstalling and reinstalling the soundcard software.

you may also want to just get to know noise technically, and how to best deal with it in adobe/CEP.

no matter what you do, you going to have some background noise. If the mic is physically near the computer, we could HEAR the cpu and power supply fans. So we relocated the mic. You can record a full minute of just SILENCE, and then go back and compare with your ears, digital silence, to your recorded silence...

...then you can put your finger on the CPU fan foir 5 seconds and HEAR the fan is no longer part of the electrical background noise.

Two things make noise a non issue...

1) always record at least several seconds of complete silence before and after each recirdd track. Do the FFT noise reduction ans you'll be amazed at the results. I once took thumping sneakers in a dryer out of a recording with it.

2) always do numerous signal level tests before recording a track, to achieve a high signal to noise ratio without clipping. The lower the noise is in relation to the quietest part of your track is a figure of merit.

Plus, that digital noise reduction built-in to adobe/CEP is VERY good.

a CPU is by nature an electriclly very "noisy" environment. The power supplies are switching power supplies, which make noise. All the little muffin fans each make noise. They are small motors, sure... sharing ground and located physically very close.

the collective effect of the normal computer is very noisy, to record just silence for a full minute in a microphone. You can run the mic cord to a carpeted vocal booth, and your STILL going to get all the CPU noise because it all runs back to be processed there.

you CAN get special heat sinks to eliminate all the muffin fans. but all that gets expensive. FFT the noise out, and always ensure decent signal to noise ratio, and its a non issue.

when I finally got around to analyzing my background noise, and FFT'ing it out... it was pretty amazing.

if nothing else, you get a tiny bit more headroom, and a slightly cleaner sound after you do FFT. You can clear up very grainy hissy mono sound clips with Audition to use to drop in songs.

Don't mean to sound like I don't take you seriously, but

a Soundblaster isn't a pro card, sorry. You'll likely get issues with any of that genre that's not designed for serious recording.

I have a Terratec installed, with Lightpipe inputs (optical, 8 channels per line) that interfaces with my digital mixer. Not bragging, it's just what I ended up with after dealing with the frustration of dealing with inferior sound cards. You get what you pay for.

Other than spending money, and reconfiguring everything, I'm not sure where to start. What mics are you using? Are you using balanced lines for them? There's a reason we all use such things -- it's to avoid the artifacts you get with consumer gear.

So much gear is available for so little that we are seduced into thinking that we don't have to spend money -- or lots of time -- to get great results. My experience has been the opposite. The more I spend (wisely, of course!) the better results I get, coupled with an analytic approach to what it is that recording amounts to. As I remarked to a person who wants me to teach her the basics of recording, "there are infinite ways to screw up a recording, and just a few to make it sound good."

It ain't the arrow, it's the Indian, but that Indian sure as hell better have a decent arrow.
