and not able to find the request section so please help
I have one request, is it possible to add some setting to remove or reject certain frequencies, I saw such a kind of facility available in Jetaudio record section you can reject certain frequency I want this for to bypass Hissing sound on line so no need to remove it separately this may be done by noise reduction by it is too complicated to do that process and find the frequencies regularly
If you are (deliberately) recording from an internal or external mic then on Windows Vista and later you may find settings in Windows Sound to filter some noise out. Right-click over the speaker icon in the System Tray > Recording Devices. Right-click over over the device you are recording with, choose “Properties” then look in the “Enhancements” tab.
Audacity does not alter the signal while recording. If you still need to remove hiss and you are sure the hiss is really only a small range of frequencies you can try Plot Spectrum then Notch Filter.
