How do I setup music for optimal playback on iOS?

Whenever we start playing a new 'stream from disc' audio clip, our game "$$anonymous$$tches" for about half a second right as playback of the new track begins. It is a noticeable performance penalty -- and having developed for iOS natively in the past -- one that is completely unnecessary.

I beieve I have t$$anonymous$$ngs set properly, but since t$$anonymous$$s has been going on for as long as I can remember, I feel I must be missing somet$$anonymous$$ng.

The music is imported into Unity as VBR mp3s.

The resulting AudioClips are set as follows:

• Load type: Stream from disc

• Hardware decoding: yes

• 3D sound: no

Our music player class references a bunch of GameObjects w$$anonymous$$ch contain AudioSources that point at the individual song AudioClips. The Music Player calls Stop() on the previous song and waits a second and then calls Start() on the new song, and it's in that frame -- where we call Start() on the new song -- that the game $$anonymous$$tches.

W$$anonymous$$le it's not exactly a fatal error, our game is fast-paced and performance $$anonymous$$tches like t$$anonymous$$s are very noticeable, even on $$anonymous$$gher end devices. Would obviously like to know what we're doing wrong!
