[Yes, I meant Lightning. But since it's a serial digital bus, it won't be able to issue the generated waveform signals directly, so the audio port would seem to be the way to go.] In iOS, what is the current way to generate precise audio tones? AVFoundation? CoreAudio? AudioUnits? -Carl _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
