Cleaning Audio For Ambience - Not so quiet suburbia.

As an exercise, decided to see if some ambience recorded in a public park could be used for say
a scene of a character walking in the woods or a forrest.

I planned my ambience and SFX tracks, background birds, footsteps, perhaps a bubbling brook, etc.

The first few were easy, a 30 second recording of me walking on gravel and an indoor water feature.
Time for a walk in the park to record some birds, as it turns out, not exactly a "walk in the park".

Guaranteed that no matter the time of day you go to a public place like a park, you will not be alone.
Other people means, other noises, very unwanted noises.

I did my 30 second recording and as predicted, lots of unwanted noises.
Below, the raw recording, quietest one of five:

Not exactly great, especially towards the end.

People talking in the distance, cars, and other general crud.

After about 10 minutes of cleaning and layering the other SFX over it,
the result is not too bad.
