Are you a writer that uses photographs, for characters, locations, or ambience?
Are you a Mac user?
Would you like to use audio files while writing for ambience?
There are a number of audio files built into the Mac operating system that can be used for ambience setting if that will help you in your writing.
For walking down a city street, there is an audio file called Concrete Jungle
For driving through a city, there is Traffic
For a backyard party with both Adults and children, there is swimming
For a business convention or a crowded airport, there is Lobby Conversation
For riding as a passenger in an airplane, there is Airplane cabin.
To access these and many other audio files, in the finder, choose the GO menu and the next to the last option should read Go to folder...
After selecting that, paste this into the box that pops up on your screen
/Applications/iMovie.app/Contents/Resources/iLife Sound Effects
The audio files are inside several folders. I recommend avoiding most of the files that are less than 2mb in size as they are mostly too short to provide much ambience.
