Perhaps this post would do better also in a more general forum, but I have a project coming up where I'd like to use Digispark Arduinos to analyze audio signals then send the FFT info wirelessly to Pure Data. I haven't gotten the equipment to futz with yet, but my question is this:

Is it in principle possible to taken a serial stream of data representing FFT bin amplitudes, and then get them into rifft~ for resynthesis? What's involved here? Some sort of status/frame bit, maybe? Some other object maybe an external other than rifft~? Maybe somebody's already done this?

Thanks so much!

Oh, I just came across the ArduinoFFT and ArduinoFHT libraries, and they have a Pd patch example for a spectrum display! But my question still remains... Maybe I should just create a bank of osc~ of the corresponding bin frequencies?
