I have MP3 files with finely-tuned compression from an audio app.
If I use them in my Flash movie, and disable audio compression in "Publish Settings"... will Flash definitely not touch the files and use whatever MP3 compression settings the files have?
Or... will flash convert them into raw audio?
If you tell it not to compress it and it's a format the native JIT compiler understands don't worry about compression. If you use a format outside flash's native capability then things get complicated.
