Where is Flash audio stream cached (Macintosh OS X)

(On a Macintosh, OS X)

On a web page with an embedded Flash audio player, I click the button, it starts playing, and the little bar gradually fills, showing that the entire file (70 minutes in this case) is being downloaded and cached on my computer. Question: Where is the file cached/stored? I know where to find cached Flash video (.flv) files (such as YouTube videos), but Flash audio files don't appear in the same place. I have Audio Hijack, so can record the audio as it plays, but I'd rather keep the original file, if I could find it.

Does anyone know where an embedded Flash audio player caches downloaded files on my computer?
