Voice Changer / Recorder - Free!

[iphoneinlondon]

Before everyone huffs & puffs at a repeated threat (lol).. I've read all the threads on phonegangster, voice candy, spoofcard, spoof app etc etc etc..

They all need paying to buy minutes - that's ONLY because it gives you the function to hide your caller id and change to something anonymous.

But what if all you wanted was something to change the voice (same way you can with voice candy, spoofcard, spoof app etc) - that way you wouldn't have to buy minutes from the a tele company right?

Basically, none of those apps works for people in the UK wanting to install the app and call direct from the iPhone. I can hide my number via 141 or even not hide it I aint too bothered.. just would be really funny to use this app on a few friends.. something to change my voice to a boy/girl/baby etc etc.. high pitch/low pitch.

Gettin my drift guys?

P.S. What language you guys using to code? Is it like java/C/Perl? etc..
I myself only do html/php and started c++ but dropped it, have a mate who has a distinction in programming, she could be quite usefull here
