removing background buzz during recording

[mahaju]

Hi I am new to music recording and new to this forum as well
I am learning to play electronic keyboard and would like to use my headphone's mic to record some of it in my laptop. But after I recorded I can hear a strange white noise like buzz in the end product (I was actually recording a video from my webcam, using the HP webcam software provided with the laptop while recording sound using a head phone mic, so it's not just audio either)
More over, my keyboard is not an advanced type, so it also produces an annoying buzz when powered on (I think it's because of the 60Hz ac power supply but I'm not sure). Anyway I think it is also contributing to the background noise in my recordings.
Is there any way I can remove such humming sounds at the mic level, that is, run some kind of software in Windows which runs in the background and filters out such noises real time while recording? Or do I need to do my recordings through another software? If so, could you please suggest which software I can use, which will allow me to record audio/video as well as just audio ?

Thanks in advance.

It's always better to eliminate noise before recording, but there are methods for removing noise after the fact. Look into noise gate plugins and noise removal plugins. You might also want to download Audacity and load some of your noisy recordings into it. It has some noise gate/removal plugins that might help you clean up your tracks.

It's possible to eliminate noise in real-time, but you would either need an external noise suppressor box or a software plugin to monitor through, which could cause latency. If you don't need to remove the noise in real-time, then it's better to do it post-recording because you can have more control over the noise that is being removed.

Guitarplayr is right, It is very important to start with the sound that you want as it gets very messy to try to edit things out afterwards. Your mix will only sound as good as the weakest component, if your input signal is rubbish, your recording is going to sound rubbish, if you are recording an inexperienced musician the recording will sound rubbish so try to get everything sounding perfect to eliminate the need for post-record editing.

If it's a 60Hz hum, try recording with your laptop on battery power - unplug the power supply.
