Hi all, 

I wonder why you guys didn't implement a "real" or proper FFT and IFFT method for the Web Audio API. I wanted to implement some signal processing stuff with the API as I recognized the lack of  getting complex values buffers. From my understanding offering a real FFT and IFFT method should be quite simple as you definitively conduct a FFT somewhere in the background. 

From my point of view, it would be a great benefit for the API and future audio applications in browsers if there would be the (native) possibility to apply a FFT and IFFT as these are the main tools for signal processing stuff as you all know. I'm quite sure you agree with me in this point. Hence, I wonder if there is a chance to include these features in the API. Probably, you had a special reason for not including a real general-prupose FFT and IFFT method?

Best wishes, 
Michael
