Remove or reduce noise from a recorded audio using FFMPEG

Question

Is it possible to remove/reduce noise from an already recorded audio file (.mp3/.wav) using FFMPEG?

What is the command?

Solution 1

A bit late, but if anyone finds this helpful, I wrote a simple script to do exactly that (it reduces noise from both audio and video files), find it here: https://github.com/yonilevy/noiseclean

Solution 2

Directly with FFMPEG is not possible, because it is only encoder/converter of various audio/video formats, you need third party tool like Audacity (http://wiki.audacityteam.org/wiki/Release_Notes_2.0.0), which is free or Adobe Audition, which is paid.

the end result introduces some new noise, kind of sounds like watery or beeping. but it did help remove the noise from a crappy video I had.
