Now I bought both caf apps for nothing, all I want is to put audionotes into iTunes and these do something else that is apparently not that what a waste! I got two apps and no use for them! Sometimes you just need a refund, you know?

Works great and awesome developer support!

This is a quick easy way to create the IMA 4 variant of .caf audio, which still sounds good but keeps the file size down.
Simple to use as you just select the source file and destination and bam it's done!
I had some other technical questions regarding .caf files and the developer was quick to respond and super helpful.
Great stuff all around!
Thanks so much!

Tried to convert .snd file, opened Adobe app instead, did nothing else.

This app should be taken off the store until it is fixed and tested.
