Question

I’m about to start developing an iOS application for audio processing. At this moment it is not quite sure what the requirements for the application are since this is a research project. But basic requirements are at least to detect cords, on-sets from mic input. Therefore I value your opinion on available libraries which you think are good for this kind of work. I would like to stay away from third party libraries as much as possible.

Answer 1

I use audio units.
No third party stuff, just plain audio units which is the best audio interface on iOS anyway.
Slightly tricky to start with, but read the docs and you’ll be good to go.
