does anyone know of a good tutorial or book on sound and programming. one of the projects i would like to do is to create a tone generator, programmitacly. Maybe have basic controls to adjust the pitch and or frequency of a tone generated by my computer. I didn't know if i would want to use c ,objective-c, x-code, python etc. i tried googling like: tone generator, core audio tutorial etc. but couldn't find anything specific for the platform i would be using a macbook pro with the developer tools installed running 10.5.6, any help would be appreciated.
