I'm looking at getting started with simple mobile app development. Corona SDK looks like a pretty nice fit for some of the ideas I'd like to toy with. I'm wondering if it is possible to do real time audio analysis with it? Could I for instance build a simple guitar tuner with Corona?
Well, the answer is yes. It's right there on the very page that I actually scanned before posting my question. It's also supersimple. I don't even have to write my own FFT. At least for frequency analysis it's as easy as:
freq = recording:getTunerFrequency()
I don't know about getting access to raw samples and doing your own computations on them though.
