[Rwp] Help with noise removal

Mon May 23 19:55:42 EDT 2016

So basically I've recorded an audio demo of an app I'm building on an 
Olympus DM 520. Unfortunately my old, better-quality mics are long gone. 
I'm in the closet of a loud apartment complex and want to scoop out the 
background hiss/traffic noise which I can't get rid of any other way. I 
tried to speak slowly with spaces between sentences, but some sentences 
got flubbed and need to be removed. There are also points where somewhat 
quieter phone audio needs to be heard more clearly, so I'll probably 
apply some compression to even out the levels. The whole clip is 
probably 10 minutes, no longer than 15.

It doesn't seem too demanding, and I thought Reaper plus its 
accessibility plugin(s) would be a great way to improve my audio editing 
chops. I don't care about nailing the quality, especially as I start out 
by apologizing for the quality but noting that I'm working with what 
I've got. I just wanted to clean it up a bit, and while I agree that a 
good-quality recording is the best start, I unfortunately don't have that.
