Playing FLAC on apple products?

[FrankMiller]

Vox and Onkyo HF Player for iOS both handle FLAC audio playback.

One requirement to consider is that it must be possible to create a playlist that contains several instances of the same track. Many players either cannot do that or don’t do it well.
Vox didn’t work for me but I don’t remember exactly why. I didn’t know Onkyo HF, thanks for the recommendation, I am downloading it right now so I can test it. 

Either way, “foobar2000” still works well.

In Vox you can either use the 'Add to Queue' function the amount of times you want to play the track, or add the sound file to the library with different files names, such as 'Ocean Surf 1', Ocean Surf 2', etc. Not the best option, but works.
