Noise supression and mic boost?

I've got an ASUS P5Q Pro motherboard that has a realtek chipset. In Windows I use the utility packaged with the driver to boost the microphone and do some noise suppression. It works surprisingly well.

I was wondering if there is something similar in Ubuntu that would improve the quality of my on-board audio for podcasting.

Recording in Ubuntu without any tweaks sounds like recording in Windows without any tweaks, so I'm just hoping there is some super-awesome software out there that I could set up to do this. (Perhaps I just need to force myself to learn JACK again?)

Thanks in advance, I look forward to switching back to Ubuntu for recording my podcast :)

I am interested in this too. until few days ago my mic was great. Then i mess up a little with the settings and when finally i was able to make the mic work again it had a strong noise. Thus I am sure that there is an option to improve the sound. But i do not know which is it.

Is there anyone that can help?

Thank you in advance for your time :)

I'm occasionally using Paltalk and I am also having some problems with noise. I really hope Ubuntu will implement some noise suppression thingy what would filter out everything that isn't voice.
