Adobe Audition: Nasa Soundscape- 'Editing and Fixing Sounds'

Has someone coughed right in the middle of a beautiful orchestra recital? Has a plane from British Airways not received your email about the recording session you'd planned to have in your garden?

Fear not, Adobe Audition has the means to fix that.
For this lecture, we were given multiple sound clips to try and fix, using either the 'Time Selection Tool' to manually cut out, or reduce the sound from a particular wave/pitch... or having the program learn the pattern of a particular sound- most prominent in background noise- and removing repetitive sounds accordingly.

While some sounds may ruin a clip, others may be alright to edit, remove or reduce volume, keeping your audio clean and in control.

Machine noises and noises that you wish to remove, that exist on their own, are easier to clear up, but voices it seems are a lot harder, due to their vocal range.

Despite this though,  the 'Spot Healing Brush Tool' can be a means of covering the anomaly.  

Though it's a careful process, of balancing the degree of which to change a track before ruining the clip.

Our second exercise had us creating a new sound track in influence of Nasa video footage. See below my example:

This helped understand the process and bending the program's tools to your own individual task.
Unfortunately, however, the soundscape lost a lot of its higher pitch whistling, so maybe I've either overpowered it with the crackling, and beeping sounds, or the sound was too soft to hear once exported. About 5 seconds in you start to hear it suddenly, but then it's disappears again, as quickly as it came.
This is something I intend to re-upload within the week, to see if it the changes improve the overall clip... and also something to keep in mind, for future work in 'Soundscape'.
