serving large media files from the assets folder in rails

问题

I want to put some rather large sound files into my assets folder in rails.

/app/assets/sounds
--- file1.wav
----file2.wav

when calling them thru the following URL

http://localhost:3000/assets/file1.wav

Rails (3.2.x) the file will be "served" (somehow) but I can never play it in the browser.

If however I put those files into the public folder they will be served and can be played.

I assume this is related to the fact that the public folder isn't touched by rails but is served by rack (afaik). I found a solution to use send_file but is this really needed?
