What codecs can be used by iOS ringtone files (.m4r). I know only about AAC and ALAC, is there anything else? I can't find any official information on this question.

As Global nomad said in the comments, this seems to be a custom chip, and their website doesn’t contain any information on the chip.
However, ABI Research has a teardown of the chip, although I don’t know how comprehensive or thorough it is. The (paid) report can be found at http://www.abiresearch.com/research/1009855. The list of the documents in the report reads “Specification”. This could be provided by Texas Instruments, or it could be compiled by ABI.
The search results on the website say, "This file is not available to the public, but it is available for purchase.” There isn’t an obvious buy button, so it’s possible that we can’t purchase it. But that might be worth chasing up — that’s the best that I can fine.
PhoneView can access pretty much any file on any iOS device, it doesn't matter what version of iOS you are running.
1...Launch PhoneView and go to preferences and make sure that (Show entire disk (Advanced Disk Mode), is checked).
2...In the window to your left select "Disk" Then go to Library -> Ringtones. This is where the ringtones are stored.
3...For the alert sounds go to System -> Library -> Audio -> UISounds. This is where all of the alert sounds are stored.
If you have custom made or downloaded any ringtones in iTunes or other programs, you can find them in the window to your left under Ringtones.

I dont know if this will help you at all but I use DBPower Amp Converter and batch converter for all my sounds. It has a lot of codecs to choose from not sure if this is what you need but give it a shot maybe it;ll work.
