Regarding Audio Recording in Vista

Hi All,
When I record a sound using a mic from my application, the recorded
sound does not match with the input sound. This maybe due to Noise or
Distortion. I know it is not possible to reproduce a pure signal as
such.I don't know whether my recorded file is within the allowed
threshold limit. I just want to know is there any threshold level ,
specific for the driver ? Where to look for information on noise level
or distortion specified by the manufacturer ?


Thanks in Advance

Try muting the speakers and / or lowering the recording level for the
microphone.

There are couple of possibilities here. If you are using a notebook
computer, some notebooks introduce electronic noise when you are charging the
battery. So the first thing you should do is disconnect the battery charger
from a notebook computer and that is what you are using. If this is the
problem, it can sometimes be rectified just by reversing the plug in the
outlet. Otherwise you may have to find a solution that your local Radio Shack.

The other more common problem is that a lot of soundcards built onto the
motherboard are not shielded properly and will pick up electronic noise from
within the computer enclosure. The only way around this is to use a USB Sound
pod which is just a sound card that sits outside of the computer. The audio
is injected directly into the Computer Processing Unit and bypasses
electronic noise from within the computer.
