Floor the noise
Brusfri is a cutting-edge noise reducing app for iPhone and iPad (also available as AU/VST/AAX plugin for Mac/Windows). It reduces unwanted background noise, while still retaining the sound quality of the wanted sound.
Using Brusfri is simple - all that's needed is a short sample of the unwanted noise. Once Brusfri has learned what the noise sounds like, it will start reducing it.
Brusfri is also available for Mac/Windows as a VST/AU/AAX plugin
The main component of Brusfri is the LEARN button. This is Brusfri's "ear" and its most important control. 
To use it, simply playback the noise that you want to reduce, press and hold the LEARN button for about 1-3 seconds, and you're done. Brusfri will then use this noise snippet to reduce the overall noise. (Therefore, it is very important that the ear is only fed with the noise that you want to reduce)
A handful of extra options are also available:
There are two ways to use Brusfri on iOS:
Standalone and AU plug-in.
In Standalone, Brusfri can import sound from other apps (using the 'Open in...' command). It can also extract audio from a video clip in the Camera Roll. When the noise reduction is complete, the audio can be exported to any destination.
When used as a AUv3 plug-in, it processes the sound in real-time. It receives the audio from a host application (or DAW), such as GarageBand. It is recommended to only use Brusfri as an insert effect on a single track.
