Static in Windows XP Voice Recording

[rhsiao]

Hi, I am using Windows XP's built in voice recorder to record some narrative wav file. It turned out there is audible static sound during the silence between words. The static sound volume is just 1/5 of the real speech, but it is still bothersome. I'm wondering:

1. Has anyone have the same experience (Could it be my computer's problem)?

2. Could it be from other near by appliances?

3. Any suggestion on the fix?

Thanks.

I suspect it is the sensitivity of the microphone.

If I use the mic that comes with the computer, I get a fuzzy background, but I use my "normal" mike and record on a casette then transfer, via LINE IN, to the computer it is OK.

The good news is that COOL EDIT (likely others can, but Acoustica can not) can remove it for you. Use TRANSFORM > NOISE REDUCTION and select a sample between your words.

Hi Robert,

Audacity can also remove the noise and it's free

Thanks JRR and cici for your advice.

I happen to have Audacity already installed in my computer so I first gave that a try. I scan thru the help section but did not find instruction on reducing noise. cici can you tell me the path to the noice reduction function?

For noise removal in "Audacity" select 'Effect"

It's in the menu.

Duh.....

I did not highlight any section of sound so the Noise Reduction feature did not show the first time.

And WOW!!! WOW WOW WOW!!! This Noise Reduction feature is amazing!!! Works beautifully.

Thanks folks!
