where are the Ultra Voice Changer/Deluxe Ultra Voice Changer favorites stored ?

[Kimusoft]

When you save a favorite, it is saving to your sd card.  You should be able to find the saved favorites under one of the following directories:

/sdcard/Android/data/com.kimusoft.ultra_voice_changer/

/mnt/sdcard/Android/data/com.kimusoft.ultra_voice_changer/ 
/Android/data/com.kimusoft.ultra_voice_changer/  

Note: Even though it looks like 3 directories, it's the same directory. But, depending on how you access the directory, the path may appear in one of the 3 different forms.
