In openFrameworks iOS 0.9.8, the audioInput example doesn’t seem to run. I found this solution:
“The audioinput example in the 9.0 release compiles and runs, and can play sound, but doesn’t receive any audio input. I removed the ofSoundPlayer, and now the audio input does work. so I guess there’s a conflict between ofSoundStream and ofSoundPlayer”
Also, it might be needed to add a Privacy – Microfone item to the plist, and write a message there (can be a simple “Yes”), see image below.
