Hi. I am looking for apps on iOS to batch convert .caf, .aif, .aiff, .m4a and .wav files to .mp3. The apps can be from the app store or Cydia, but I have looked on both and also on google and have not found what I am looking for. I have found some apps that use the internet for conversion and those are ok, but I would rather have an app that can convert locally without the internet and I have not found an app like that yet. I have tried audio share, but it can not convert to .mp3 and it can not batch convert. You have to convert every file one at a time. Thank you.
