Stream from disc audio file, memory management?

I’m pretty sure that stream from disc is meant to be able to play musics while not having to allocate memory (or a little) for it, thus making loading faster and leaving more memory available, but when I use stream from disc with my musics, the profiler tells me that sounds eat up to 10 times the memory used with the setting “compressed in memory”. Could anyone explain to me this stream from disc setting?

The profiler in Unity shows greatly exaggerated memory use from streaming. It’s not correct. To see the real usage, run profiler against the build deployed to the actual target device (iPad etc).
