Galaxy S4 to Galaxy S6 Smart Switch did not transfer recordings that I use for ringtones

[AC Question]

I recorded several songs that my daughter sang with her yuke and I use them as ringtones and alarm tones. I backed up the s4 with Kies on my Mac. The files are there, but I don't know how to get them on to the new phone. I also did the smart switch, but the recordings did not transfer.
