Suggestion for program to import audio files into iPhone

[Tricon7]

I need a way to import audio files (non-music) into my iPhone. iTunes is absolutely horrendous (stick a fork in me, I'm done with it), and iFunbox is good for moving music, but it can't find non-music audio on my computer. Other programs like iTools bring stuff from my iPhone to my computer, but not vice-versa.
