was the environment already noisy?
Well but there is a program (Nero Wave Editor) which can help.
On the interface, click ENHANCEMENTS on the top and then select NOISE REDUCTION and it will present you with some other interface with sliders and then you move then more to the right.

If it has a switch labeled conf/dict , put this switch in the dict mode. This switch is a record sensitivity control, in the conference position it will pick up almost any noise in the room. In the dict,position which is short for dictate, it will have less record sensitivity and will only pick up sounds very close to the microphone and eliminate background noises
You cannot remove the background noise of already recorded material unless you have special software for that purpose. It is available, but costly. To eliminate some background noise, you may in the future, try to muffle the microphone by turning down the volume and recording by moving the device closer to the sound sources. Some folks put a wind sock over the recorder, as you may have noticed during TV News recordings on street events or at a studio. Try a wool or thick sock over the recorder and see if that helps.
Get a wired lapel microphone and plug it into the microphone input on your Dell. The onboard mic is designed to record all ambient sounds. You want a different product to get the result you're looking for.
no problem with..record some part of the start with no voice just a 5-10 seconds remain quite...just kept running the recording...then start and record your voice after which install AudaCITY Software and drag your audio file in it and then select the first 5-19 seconds recording which was just the background kept recording selecting the part go to Effects -> Noise Removal then press Get Profile,
after which again select all the track by: Control + A key on PC and then go to Effects Noise Removal move the bar to the left side...and press ok/continue key....now your track is very much clean by the noise...and
for sound loudness select all the track and go to Effects -> Normalize then again Effects -> Amplify put the slider value to -0.1 of what the value is shown.
a bit late, only just saw this question. my understanding is that clearing up background noise is a specialist task. if you look at a sound wave it's really difficult to discern the main wave from additional noise. and although its possible to edit out the background of a photograph, that gets a lot trickier with a video if you follow my metaphor. the best most of us can do is open the file in a sound app (i'm on a mac so i use quicktime for this) and find the menu option to raise the volume. Now its absolutely possible that someone has come up with some new software that i haven't heard of yet of course. however good practice is; make sure you record at a good volume to start with-
either do an audio test and listen back or set the levels with a
The pic looks like a TRC5880? If thats the case they are naturally quite noisey. The motors vibrate too much in my opinion. Theres not much you can do with it unfortunately. Suggest a new recorder or get that one repaired.
