I can record sound as .mp3 file. But there is a heavy background noise. However if I lower the volume level of MIG on alsamixer I can reduce the noise. But the sound recorded is also reduces.
Not sure how to fix your problem, But you should use audacity to record your audio and then use the Noise Removal tool and then use the compressor filter with normalize checked.
Youtube have many tutorials on audacity using the noise removal tool, compressor and normalize effect filters.
If you decide to use audacity, make sure to select pulse from the drop down box next to the microphone. Also, select the Mic from the sound volume control settings as the recording source.

It works but there is heavy background noise. Then I started googling around for advice. I found many threads in re of background noise. But I haven't discovered a solution to my problem yet.
Yeah, it seems you have a complex case since there aren't many volunteers to help your solution.
I'm not a sound expert but I seen these tutorials that help my recording and editing of audio. Visit this site and watch these videos http://goinglinux.com/screencasts.html

I wish I knew the cause of your problem to be more helpful : /
I was reading your other post. It seems you want to record google translate. If this is is the case, you need to choose the Mix or Monitor channel as the recording source. Either of these channels if supported by your soundcard will record audio that is playing on your desktop. In fact, it will record all channels including Mic and line if there devices connected to them.
Select Mix or Monitor from alsamixer if available. If you don't have these channels, then you need to use the pulse audio volume control. The package name is pavucontrol.
Open pavucontrol and play something with audio for a test run. As the auidio is playing, go to the recording tab and click the dropdown box that has your soundcard's name and choose Monitor of soundcard's name.
In Monitor mode this will record whatever you hear playing through your speakers including Mic and Line.
Once you have it in Mix or Monitor mode, use either ffmpeg or audacity to record google translate.

Hi,
It seems quite strange. I don't have MIC attached to the computer except USB external speakers.
Performed following test;
Installed pavucontrol. However it didn't help. I can't play .mp3 files on it. Neither I can record "google translate" running ffmpeg/gnome-sound-recorder. It seemed having something recorded but nothing on playback. Even after uninstalling pavucontrol I can't record "google translate" anymore.

I assured you I would never give bad info without experiencing it myself. I personally use these methods myself when recording audio from Mic and/or internet streams and it works quite well.
As for the pavucontrol program it shouldn't have messed your settings, don't know why it did. I've used this program many times in certain distros.
