Windows – How to extract clear voice from a noisy audio file

audioaudio recordingsoftware-recwindows 7

I have some noisy audio files, which are voice recordings or lectures. There is no music, but the recordings are noisy.

Sometimes, the voice is not clear. Is there any software that can extract the clear voice out of those audio files? It would be better to have automated processing and batch processing supports.

I'm using Windows 7.

Regardless of OS, Audacity can do this just fine. So says Wikipedia:

Noise Removal based on sampling the noise to be removed. Surface noise from records, for example, can be removed with hardly any discernable effect on the music.

See this Audacity Wiki entry for Noise Removal.

As for batch, see the manual page.
