This application is for iPhone OS version 1.x (jailbroken) and thus is essentially obsolete.
Version 0.22 is now up, and it will probably soon be up on the Installer repository as well.
I have put version 0.02 up...it isn't too much different, unless you play the banjo. There is a slightly improved GUI, but I'm still waiting for someone with artistic talent to take this job from me.
Funiculus is now a working application. It still needs a lot of work to improve certain aspects of the GUI and pitch detection, but it is nevertheless functional. A binary is currently available for those wishing to test it.
I've imported the code into the SVN repository...the audio works, but the rest of the program (GUI & pitch detection) need a lot of work. If anyone wants to help out/join the project, please send me a message.
