Recommended lowest spec for .mp3 files? Sound crackling issue on device

hi all, is there a recommended spec for .mp3 audio files?

we crunched ours down to speed up gameplay, but they crackle on the new SDKs on device and emulator.

If it’s also crackling in the simulator then the problem isn’t that it’s running out of CPU. :thinking: I’m not having any luck reproducing it here. Can you post the mp3 that’s having this problem? And just to double-check, what’s the version number of the simulator?
